-    "If you are just starting with Oracle Database, consider exploring the [free Oracle 23 AI](https://www.oracle.com/database/free/#resources) which provides a great introduction to setting up your database environment. While working with the database, it is often advisable to avoid using the system user by default; instead, you can create your own user for enhanced security and customization. For detailed steps on user creation, refer to our [end-to-end guide](https://github.com/langchain-ai/langchain/blob/master/cookbook/oracleai_demo.ipynb) which also shows how to set up a user in Oracle. Additionally, understanding user privileges is crucial for managing database security effectively. You can learn more about this topic in the official [Oracle guide](https://docs.oracle.com/en/database/oracle/oracle-database/19/admqs/administering-user-accounts-and-security.html#GUID-36B21D72-1BBB-46C9-A0C9-F0D2A8591B8D) on administering user accounts and security."

-   - **Cookbook:** [self-discover](https://github.com/langchain-ai/langchain/blob/master/cookbook/self-discover.ipynb)
-
-**Abstract:** We introduce SELF-DISCOVER, a general framework for LLMs to self-discover the
-task-intrinsic reasoning structures to tackle complex reasoning problems that
-are challenging for typical prompting methods. Core to the framework is a
-self-discovery process where LLMs select multiple atomic reasoning modules such
-as critical thinking and step-by-step thinking, and compose them into an
-explicit reasoning structure for LLMs to follow during decoding. SELF-DISCOVER
-substantially improves GPT-4 and PaLM 2's performance on challenging reasoning
-benchmarks such as BigBench-Hard, grounded agent reasoning, and MATH, by as
-much as 32% compared to Chain of Thought (CoT). Furthermore, SELF-DISCOVER
-outperforms inference-intensive methods such as CoT-Self-Consistency by more
-than 20%, while requiring 10-40x fewer inference compute. Finally, we show that
-the self-discovered reasoning structures are universally applicable across
-model families: from PaLM 2-L to GPT-4, and from GPT-4 to Llama2, and share
-commonalities with human reasoning patterns.

-   - **Cookbook:** [RAPTOR](https://github.com/langchain-ai/langchain/blob/master/cookbook/RAPTOR.ipynb)
-
-**Abstract:** Retrieval-augmented language models can better adapt to changes in world
-state and incorporate long-tail knowledge. However, most existing methods
-retrieve only short contiguous chunks from a retrieval corpus, limiting
-holistic understanding of the overall document context. We introduce the novel
-approach of recursively embedding, clustering, and summarizing chunks of text,
-constructing a tree with differing levels of summarization from the bottom up.
-At inference time, our RAPTOR model retrieves from this tree, integrating
-information across lengthy documents at different levels of abstraction.
-Controlled experiments show that retrieval with recursive summaries offers
-significant improvements over traditional retrieval-augmented LMs on several
-tasks. On question-answering tasks that involve complex, multi-step reasoning,
-we show state-of-the-art results; for example, by coupling RAPTOR retrieval
-with the use of GPT-4, we can improve the best performance on the QuALITY
-benchmark by 20% in absolute accuracy.

-
-**Abstract:** Large language models (LLMs) inevitably exhibit hallucinations since the
-accuracy of generated texts cannot be secured solely by the parametric
-knowledge they encapsulate. Although retrieval-augmented generation (RAG) is a
-practicable complement to LLMs, it relies heavily on the relevance of retrieved
-documents, raising concerns about how the model behaves if retrieval goes
-wrong. To this end, we propose the Corrective Retrieval Augmented Generation
-(CRAG) to improve the robustness of generation. Specifically, a lightweight
-retrieval evaluator is designed to assess the overall quality of retrieved
-documents for a query, returning a confidence degree based on which different
-knowledge retrieval actions can be triggered. Since retrieval from static and
-limited corpora can only return sub-optimal documents, large-scale web searches
-are utilized as an extension for augmenting the retrieval results. Besides, a
-decompose-then-recompose algorithm is designed for retrieved documents to
-selectively focus on key information and filter out irrelevant information in
-them. CRAG is plug-and-play and can be seamlessly coupled with various
-RAG-based approaches. Experiments on four datasets covering short- and
-long-form generation tasks show that CRAG can significantly improve the
-performance of RAG-based approaches.

-
-**Abstract:** We introduce Mixtral 8x7B, a Sparse Mixture of Experts (SMoE) language model.
-Mixtral has the same architecture as Mistral 7B, with the difference that each
-layer is composed of 8 feedforward blocks (i.e. experts). For every token, at
-each layer, a router network selects two experts to process the current state
-and combine their outputs. Even though each token only sees two experts, the
-selected experts can be different at each timestep. As a result, each token has
-access to 47B parameters, but only uses 13B active parameters during inference.
-Mixtral was trained with a context size of 32k tokens and it outperforms or
-matches Llama 2 70B and GPT-3.5 across all evaluated benchmarks. In particular,
-Mixtral vastly outperforms Llama 2 70B on mathematics, code generation, and
-multilingual benchmarks. We also provide a model fine-tuned to follow
-instructions, Mixtral 8x7B - Instruct, that surpasses GPT-3.5 Turbo,
-Claude-2.1, Gemini Pro, and Llama 2 70B - chat model on human benchmarks. Both
-the base and instruct models are released under the Apache 2.0 license.

-
-**Abstract:** Dense retrieval has become a prominent method to obtain relevant context or
-world knowledge in open-domain NLP tasks. When we use a learned dense retriever
-on a retrieval corpus at inference time, an often-overlooked design choice is
-the retrieval unit in which the corpus is indexed, e.g. document, passage, or
-sentence. We discover that the retrieval unit choice significantly impacts the
-performance of both retrieval and downstream tasks. Distinct from the typical
-approach of using passages or sentences, we introduce a novel retrieval unit,
-proposition, for dense retrieval. Propositions are defined as atomic
-expressions within text, each encapsulating a distinct factoid and presented in
-a concise, self-contained natural language format. We conduct an empirical
-comparison of different retrieval granularity. Our results reveal that
-proposition-based retrieval significantly outperforms traditional passage or
-sentence-based methods in dense retrieval. Moreover, retrieval by proposition
-also enhances the performance of downstream QA tasks, since the retrieved texts
-are more condensed with question-relevant information, reducing the need for
-lengthy input tokens and minimizing the inclusion of extraneous, irrelevant
-information.

-
-**Abstract:** Retrieval-augmented language models (RALMs) represent a substantial
-advancement in the capabilities of large language models, notably in reducing
-factual hallucination by leveraging external knowledge sources. However, the
-reliability of the retrieved information is not always guaranteed. The
-retrieval of irrelevant data can lead to misguided responses, and potentially
-causing the model to overlook its inherent knowledge, even when it possesses
-adequate information to address the query. Moreover, standard RALMs often
-struggle to assess whether they possess adequate knowledge, both intrinsic and
-retrieved, to provide an accurate answer. In situations where knowledge is
-lacking, these systems should ideally respond with "unknown" when the answer is
-unattainable. In response to these challenges, we introduces Chain-of-Noting
-(CoN), a novel approach aimed at improving the robustness of RALMs in facing
-noisy, irrelevant documents and in handling unknown scenarios. The core idea of
-CoN is to generate sequential reading notes for retrieved documents, enabling a
-thorough evaluation of their relevance to the given question and integrating
-this information to formulate the final answer. We employed ChatGPT to create
-training data for CoN, which was subsequently trained on an LLaMa-2 7B model.
-Our experiments across four open-domain QA benchmarks show that RALMs equipped
-with CoN significantly outperform standard RALMs. Notably, CoN achieves an
-average improvement of +7.9 in EM score given entirely noisy retrieved
-documents and +10.5 in rejection rates for real-time questions that fall
-outside the pre-training knowledge scope.

-
-**Abstract:** Despite their remarkable capabilities, large language models (LLMs) often
-produce responses containing factual inaccuracies due to their sole reliance on
-the parametric knowledge they encapsulate. Retrieval-Augmented Generation
-(RAG), an ad hoc approach that augments LMs with retrieval of relevant
-knowledge, decreases such issues. However, indiscriminately retrieving and
-incorporating a fixed number of retrieved passages, regardless of whether
-retrieval is necessary, or passages are relevant, diminishes LM versatility or
-can lead to unhelpful response generation. We introduce a new framework called
-Self-Reflective Retrieval-Augmented Generation (Self-RAG) that enhances an LM's
-quality and factuality through retrieval and self-reflection. Our framework
-trains a single arbitrary LM that adaptively retrieves passages on-demand, and
-generates and reflects on retrieved passages and its own generations using
-special tokens, called reflection tokens. Generating reflection tokens makes
-the LM controllable during the inference phase, enabling it to tailor its
-behavior to diverse task requirements. Experiments show that Self-RAG (7B and
-13B parameters) significantly outperforms state-of-the-art LLMs and
-retrieval-augmented models on a diverse set of tasks. Specifically, Self-RAG
-outperforms ChatGPT and retrieval-augmented Llama2-chat on Open-domain QA,
-reasoning and fact verification tasks, and it shows significant gains in
-improving factuality and citation accuracy for long-form generations relative
-to these models.

-correct reasoning path towards the solution. We conduct experiments of
-Step-Back Prompting with PaLM-2L, GPT-4 and Llama2-70B models, and observe
-substantial performance gains on various challenging reasoning-intensive tasks
-including STEM, Knowledge QA, and Multi-Hop Reasoning. For instance, Step-Back
-Prompting improves PaLM-2L performance on MMLU (Physics and Chemistry) by 7%
-and 11% respectively, TimeQA by 27%, and MuSiQue by 7%.

-**Abstract:** Large Language Models (LLMs) play powerful, black-box readers in the
-retrieve-then-read pipeline, making remarkable progress in knowledge-intensive
-tasks. This work introduces a new framework, Rewrite-Retrieve-Read instead of
-the previous retrieve-then-read for the retrieval-augmented LLMs from the
-perspective of the query rewriting. Unlike prior studies focusing on adapting
-either the retriever or the reader, our approach pays attention to the
-adaptation of the search query itself, for there is inevitably a gap between
-the input text and the needed knowledge in retrieval. We first prompt an LLM to
-generate the query, then use a web search engine to retrieve contexts.
-Furthermore, to better align the query to the frozen modules, we propose a
-trainable scheme for our pipeline. A small language model is adopted as a
-trainable rewriter to cater to the black-box LLM reader. The rewriter is
-trained using the feedback of the LLM reader by reinforcement learning.
-Evaluation is conducted on downstream tasks, open-domain QA and multiple-choice
-QA. Experiments results show consistent performance improvement, indicating
-that our framework is proven effective and scalable, and brings a new framework
-for retrieval-augmented LLM.

-
-**Abstract:** In this paper, we introduce the Tree-of-Thought (ToT) framework, a novel
-approach aimed at improving the problem-solving capabilities of auto-regressive
-large language models (LLMs). The ToT technique is inspired by the human mind's
-approach for solving complex reasoning tasks through trial and error. In this
-process, the human mind explores the solution space through a tree-like thought
-process, allowing for backtracking when necessary. To implement ToT as a
-software system, we augment an LLM with additional modules including a prompter
-agent, a checker module, a memory module, and a ToT controller. In order to
-solve a given problem, these modules engage in a multi-round conversation with
-the LLM. The memory module records the conversation and state history of the
-problem solving process, which allows the system to backtrack to the previous
-steps of the thought-process and explore other directions from there. To verify
-the effectiveness of the proposed technique, we implemented a ToT-based solver
-for the Sudoku Puzzle. Experimental results show that the ToT framework can
-significantly increase the success rate of Sudoku puzzle solving. Our
-implementation of the ToT-based Sudoku solver is available on GitHub:

-
-**Abstract:** Large language models (LLMs) have recently been shown to deliver impressive
-performance in various NLP tasks. To tackle multi-step reasoning tasks,
-few-shot chain-of-thought (CoT) prompting includes a few manually crafted
-step-by-step reasoning demonstrations which enable LLMs to explicitly generate
-reasoning steps and improve their reasoning task accuracy. To eliminate the
-manual effort, Zero-shot-CoT concatenates the target problem statement with
-"Let's think step by step" as an input prompt to LLMs. Despite the success of
-Zero-shot-CoT, it still suffers from three pitfalls: calculation errors,
-missing-step errors, and semantic misunderstanding errors. To address the
-missing-step errors, we propose Plan-and-Solve (PS) Prompting. It consists of
-two components: first, devising a plan to divide the entire task into smaller
-subtasks, and then carrying out the subtasks according to the plan. To address
-the calculation errors and improve the quality of generated reasoning steps, we
-extend PS prompting with more detailed instructions and derive PS+ prompting.
-We evaluate our proposed prompting strategy on ten datasets across three
-reasoning problems. The experimental results over GPT-3 show that our proposed
-zero-shot prompting consistently outperforms Zero-shot-CoT across all datasets
-by a large margin, is comparable to or exceeds Zero-shot-Program-of-Thought
-Prompting, and has comparable performance with 8-shot CoT prompting on the math
-reasoning problem. The code can be found at

-**Abstract:** Instruction tuning large language models (LLMs) using machine-generated

-generated data, we introduce LLaVA: Large Language and Vision Assistant, an
-end-to-end trained large multimodal model that connects a vision encoder and
-LLM for general-purpose visual and language understanding.Our early experiments
-show that LLaVA demonstrates impressive multimodel chat abilities, sometimes
-exhibiting the behaviors of multimodal GPT-4 on unseen images/instructions, and
-yields a 85.1% relative score compared with GPT-4 on a synthetic multimodal
-instruction-following dataset. When fine-tuned on Science QA, the synergy of
-LLaVA and GPT-4 achieves a new state-of-the-art accuracy of 92.53%. We make
-GPT-4 generated visual instruction tuning data, our model and code base
-publicly available.

-
-**Abstract:** Believable proxies of human behavior can empower interactive applications
-ranging from immersive environments to rehearsal spaces for interpersonal
-communication to prototyping tools. In this paper, we introduce generative
-agents--computational software agents that simulate believable human behavior.
-Generative agents wake up, cook breakfast, and head to work; artists paint,
-while authors write; they form opinions, notice each other, and initiate
-conversations; they remember and reflect on days past as they plan the next
-day. To enable generative agents, we describe an architecture that extends a
-large language model to store a complete record of the agent's experiences
-using natural language, synthesize those memories over time into higher-level
-reflections, and retrieve them dynamically to plan behavior. We instantiate
-generative agents to populate an interactive sandbox environment inspired by
-The Sims, where end users can interact with a small town of twenty five agents
-using natural language. In an evaluation, these generative agents produce
-believable individual and emergent social behaviors: for example, starting with
-only a single user-specified notion that one agent wants to throw a Valentine's
-Day party, the agents autonomously spread invitations to the party over the
-next two days, make new acquaintances, ask each other out on dates to the
-party, and coordinate to show up for the party together at the right time. We
-demonstrate through ablation that the components of our agent
-architecture--observation, planning, and reflection--each contribute critically
-to the believability of agent behavior. By fusing large language models with
-computational, interactive agents, this work introduces architectural and
-interaction patterns for enabling believable simulations of human behavior.

-**Abstract:** Solving complicated AI tasks with different domains and modalities is a key
-step toward artificial general intelligence. While there are numerous AI models
-available for various domains and modalities, they cannot handle complicated AI
-tasks autonomously. Considering large language models (LLMs) have exhibited
-exceptional abilities in language understanding, generation, interaction, and
-reasoning, we advocate that LLMs could act as a controller to manage existing
-AI models to solve complicated AI tasks, with language serving as a generic
-interface to empower this. Based on this philosophy, we present HuggingGPT, an
-LLM-powered agent that leverages LLMs (e.g., ChatGPT) to connect various AI
-models in machine learning communities (e.g., Hugging Face) to solve AI tasks.
-Specifically, we use ChatGPT to conduct task planning when receiving a user
-request, select models according to their function descriptions available in
-Hugging Face, execute each subtask with the selected AI model, and summarize
-the response according to the execution results. By leveraging the strong
-language capability of ChatGPT and abundant AI models in Hugging Face,
-HuggingGPT can tackle a wide range of sophisticated AI tasks spanning different
-modalities and domains and achieve impressive results in language, vision,
-speech, and other challenging tasks, which paves a new way towards the
-realization of artificial general intelligence.

-**Abstract:** Potential harms of large language models can be mitigated by watermarking
-model output, i.e., embedding signals into generated text that are invisible to
-humans but algorithmically detectable from a short span of tokens. We propose a
-watermarking framework for proprietary language models. The watermark can be
-embedded with negligible impact on text quality, and can be detected using an
-efficient open-source algorithm without access to the language model API or
-parameters. The watermark works by selecting a randomized set of "green" tokens
-before a word is generated, and then softly promoting use of green tokens
-during sampling. We propose a statistical test for detecting the watermark with
-interpretable p-values, and derive an information-theoretic framework for
-analyzing the sensitivity of the watermark. We test the watermark using a
-multi-billion parameter model from the Open Pretrained Transformer (OPT)
-family, and discuss robustness and security.

-**Abstract:** While dense retrieval has been shown effective and efficient across tasks and
-languages, it remains difficult to create effective fully zero-shot dense
-retrieval systems when no relevance label is available. In this paper, we
-recognize the difficulty of zero-shot learning and encoding relevance. Instead,
-we propose to pivot through Hypothetical Document Embeddings~(HyDE). Given a
-query, HyDE first zero-shot instructs an instruction-following language model
-(e.g. InstructGPT) to generate a hypothetical document. The document captures
-relevance patterns but is unreal and may contain false details. Then, an
-unsupervised contrastively learned encoder~(e.g. Contriever) encodes the
-document into an embedding vector. This vector identifies a neighborhood in the
-corpus embedding space, where similar real documents are retrieved based on
-vector similarity. This second step ground the generated document to the actual
-corpus, with the encoder's dense bottleneck filtering out the incorrect
-details. Our experiments show that HyDE significantly outperforms the
-state-of-the-art unsupervised dense retriever Contriever and shows strong
-performance comparable to fine-tuned retrievers, across various tasks (e.g. web
-search, QA, fact verification) and languages~(e.g. sw, ko, ja).

-**Abstract:** Large language models (LLMs) have exhibited remarkable capabilities in
-learning from explanations in prompts, but there has been limited understanding
-of exactly how these explanations function or why they are effective. This work
-aims to better understand the mechanisms by which explanations are used for
-in-context learning. We first study the impact of two different factors on the
-performance of prompts with explanations: the computation trace (the way the
-solution is decomposed) and the natural language used to express the prompt. By
-perturbing explanations on three controlled tasks, we show that both factors
-contribute to the effectiveness of explanations. We further study how to form
-maximally effective sets of explanations for solving a given test query. We
-find that LLMs can benefit from the complementarity of the explanation set:
-diverse reasoning skills shown by different exemplars can lead to better
-performance. Therefore, we propose a maximal marginal relevance-based exemplar
-selection approach for constructing exemplar sets that are both relevant as
-well as complementary, which successfully improves the in-context learning
-performance across three real-world tasks on multiple LLMs.

-**Abstract:** Large language models (LLMs) have recently demonstrated an impressive ability
-to perform arithmetic and symbolic reasoning tasks, when provided with a few
-examples at test time ("few-shot prompting"). Much of this success can be
-attributed to prompting methods such as "chain-of-thought'', which employ LLMs
-for both understanding the problem description by decomposing it into steps, as
-well as solving each step of the problem. While LLMs seem to be adept at this
-sort of step-by-step decomposition, LLMs often make logical and arithmetic
-mistakes in the solution part, even when the problem is decomposed correctly.
-In this paper, we present Program-Aided Language models (PAL): a novel approach
-that uses the LLM to read natural language problems and generate programs as
-the intermediate reasoning steps, but offloads the solution step to a runtime
-such as a Python interpreter. With PAL, decomposing the natural language
-problem into runnable steps remains the only learning task for the LLM, while
-solving is delegated to the interpreter. We demonstrate this synergy between a
-neural LLM and a symbolic interpreter across 13 mathematical, symbolic, and
-algorithmic reasoning tasks from BIG-Bench Hard and other benchmarks. In all
-these natural language reasoning tasks, generating code using an LLM and
-reasoning using a Python interpreter leads to more accurate results than much
-larger models. For example, PAL using Codex achieves state-of-the-art few-shot
-accuracy on the GSM8K benchmark of math word problems, surpassing PaLM-540B
-which uses chain-of-thought by absolute 15% top-1. Our code and data are
-publicly available at http://reasonwithpal.com/ .

-**Abstract:** While large language models (LLMs) have demonstrated impressive capabilities
-across tasks in language understanding and interactive decision making, their
-abilities for reasoning (e.g. chain-of-thought prompting) and acting (e.g.
-action plan generation) have primarily been studied as separate topics. In this
-paper, we explore the use of LLMs to generate both reasoning traces and
-task-specific actions in an interleaved manner, allowing for greater synergy
-between the two: reasoning traces help the model induce, track, and update
-action plans as well as handle exceptions, while actions allow it to interface
-with external sources, such as knowledge bases or environments, to gather
-additional information. We apply our approach, named ReAct, to a diverse set of
-language and decision making tasks and demonstrate its effectiveness over
-state-of-the-art baselines, as well as improved human interpretability and
-trustworthiness over methods without reasoning or acting components.
-Concretely, on question answering (HotpotQA) and fact verification (Fever),
-ReAct overcomes issues of hallucination and error propagation prevalent in
-chain-of-thought reasoning by interacting with a simple Wikipedia API, and
-generates human-like task-solving trajectories that are more interpretable than
-baselines without reasoning traces. On two interactive decision making
-benchmarks (ALFWorld and WebShop), ReAct outperforms imitation and
-reinforcement learning methods by an absolute success rate of 34% and 10%
-respectively, while being prompted with only one or two in-context examples.

-**Abstract:** Traditional data lakes provide critical data infrastructure for analytical
-workloads by enabling time travel, running SQL queries, ingesting data with
-ACID transactions, and visualizing petabyte-scale datasets on cloud storage.
-They allow organizations to break down data silos, unlock data-driven
-decision-making, improve operational efficiency, and reduce costs. However, as
-deep learning usage increases, traditional data lakes are not well-designed for
-applications such as natural language processing (NLP), audio processing,
-computer vision, and applications involving non-tabular datasets. This paper
-presents Deep Lake, an open-source lakehouse for deep learning applications
-developed at Activeloop. Deep Lake maintains the benefits of a vanilla data
-lake with one key difference: it stores complex data, such as images, videos,
-annotations, as well as tabular data, in the form of tensors and rapidly
-streams the data over the network to (a) Tensor Query Language, (b) in-browser
-visualization engine, or (c) deep learning frameworks without sacrificing GPU
-utilization. Datasets stored in Deep Lake can be accessed from PyTorch,
-TensorFlow, JAX, and integrate with numerous MLOps tools.

-
-**Abstract:** Scaling multilingual representation learning beyond the hundred most frequent
-languages is challenging, in particular to cover the long tail of low-resource
-languages. A promising approach has been to train one-for-all multilingual
-models capable of cross-lingual transfer, but these models often suffer from
-insufficient capacity and interference between unrelated languages. Instead, we
-move away from this approach and focus on training multiple language (family)
-specific representations, but most prominently enable all languages to still be
-encoded in the same representational space. To achieve this, we focus on
-teacher-student training, allowing all encoders to be mutually compatible for
-bitext mining, and enabling fast learning of new languages. We introduce a new
-teacher-student training scheme which combines supervised and self-supervised
-training, allowing encoders to take advantage of monolingual training data,
-which is valuable in the low-resource setting.
-  Our approach significantly outperforms the original LASER encoder. We study
-very low-resource languages and handle 50 African languages, many of which are
-not covered by any other model. For these languages, we train sentence
-encoders, mine bitexts, and validate the bitexts by training NMT systems.

-
-**Abstract:** Today's probabilistic language generators fall short when it comes to
-producing coherent and fluent text despite the fact that the underlying models
-perform well under standard metrics, e.g., perplexity. This discrepancy has
-puzzled the language generation community for the last few years. In this work,
-we posit that the abstraction of natural language generation as a discrete
-stochastic process--which allows for an information-theoretic analysis--can
-provide new insights into the behavior of probabilistic language generators,
-e.g., why high-probability texts can be dull or repetitive. Humans use language
-as a means of communicating information, aiming to do so in a simultaneously
-efficient and error-minimizing manner; in fact, psycholinguistics research
-suggests humans choose each word in a string with this subconscious goal in
-mind. We formally define the set of strings that meet this criterion: those for
-which each word has an information content close to the expected information
-content, i.e., the conditional entropy of our model. We then propose a simple
-and efficient procedure for enforcing this criterion when generating from
-probabilistic models, which we call locally typical sampling. Automatic and
-human evaluations show that, in comparison to nucleus and top-k sampling,
-locally typical sampling offers competitive performance (in both abstractive
-summarization and story generation) in terms of quality while consistently
-reducing degenerate repetitions.

-
-**Abstract:** State-of-the-art computer vision systems are trained to predict a fixed set
-of predetermined object categories. This restricted form of supervision limits
-their generality and usability since additional labeled data is needed to
-specify any other visual concept. Learning directly from raw text about images
-is a promising alternative which leverages a much broader source of
-supervision. We demonstrate that the simple pre-training task of predicting
-which caption goes with which image is an efficient and scalable way to learn
-SOTA image representations from scratch on a dataset of 400 million (image,
-text) pairs collected from the internet. After pre-training, natural language
-is used to reference learned visual concepts (or describe new ones) enabling
-zero-shot transfer of the model to downstream tasks. We study the performance
-of this approach by benchmarking on over 30 different existing computer vision
-datasets, spanning tasks such as OCR, action recognition in videos,
-geo-localization, and many types of fine-grained object classification. The
-model transfers non-trivially to most tasks and is often competitive with a
-fully supervised baseline without the need for any dataset specific training.
-For instance, we match the accuracy of the original ResNet-50 on ImageNet
-zero-shot without needing to use any of the 1.28 million training examples it
-was trained on. We release our code and pre-trained model weights at
-https://github.com/OpenAI/CLIP.

-
-**Abstract:** Large-scale language models show promising text generation capabilities, but
-users cannot easily control particular aspects of the generated text. We
-release CTRL, a 1.63 billion-parameter conditional transformer language model,
-trained to condition on control codes that govern style, content, and
-task-specific behavior. Control codes were derived from structure that
-naturally co-occurs with raw text, preserving the advantages of unsupervised
-learning while providing more explicit control over text generation. These
-codes also allow CTRL to predict which parts of the training data are most
-likely given a sequence. This provides a potential method for analyzing large
-amounts of data via model-based source attribution. We have released multiple
-full-sized, pretrained versions of CTRL at https://github.com/salesforce/ctrl.

-**Abstract:** BERT (Devlin et al., 2018) and RoBERTa (Liu et al., 2019) has set a new
-state-of-the-art performance on sentence-pair regression tasks like semantic
-textual similarity (STS). However, it requires that both sentences are fed into
-the network, which causes a massive computational overhead: Finding the most
-similar pair in a collection of 10,000 sentences requires about 50 million
-inference computations (~65 hours) with BERT. The construction of BERT makes it
-unsuitable for semantic similarity search as well as for unsupervised tasks
-like clustering.
-  In this publication, we present Sentence-BERT (SBERT), a modification of the
-pretrained BERT network that use siamese and triplet network structures to
-derive semantically meaningful sentence embeddings that can be compared using
-cosine-similarity. This reduces the effort for finding the most similar pair
-from 65 hours with BERT / RoBERTa to about 5 seconds with SBERT, while
-maintaining the accuracy from BERT.
-  We evaluate SBERT and SRoBERTa on common STS tasks and transfer learning
-tasks, where it outperforms other state-of-the-art sentence embeddings methods.

 # langchain
 
-## 0.2.0
-
-### Deleted
-
-As of release 0.2.0, `langchain` is required to be integration-agnostic. This means that code in `langchain`  should not by default instantiate any specific chat models, llms, embedding models, vectorstores etc; instead, the user will be required to specify those explicitly.
-
-The following functions and classes require an explicit LLM to be passed as an argument:
-
-- `langchain.agents.agent_toolkits.vectorstore.toolkit.VectorStoreToolkit`
-- `langchain.agents.agent_toolkits.vectorstore.toolkit.VectorStoreRouterToolkit`
-- `langchain.chains.openai_functions.get_openapi_chain`
-- `langchain.chains.router.MultiRetrievalQAChain.from_retrievers`
-- `langchain.indexes.VectorStoreIndexWrapper.query`
-- `langchain.indexes.VectorStoreIndexWrapper.query_with_sources`
-- `langchain.indexes.VectorStoreIndexWrapper.aquery_with_sources`
-- `langchain.chains.flare.FlareChain`
-
-The following classes now require passing an explicit Embedding model as an argument:
-
-- `langchain.indexes.VectostoreIndexCreator`
-
-The following code has been removed:
-
-- `langchain.natbot.NatBotChain.from_default` removed in favor of the `from_llm` class method.
-
-### Deprecated
-
-We have two main types of deprecations:
-
-1. Code that was moved from `langchain` into another package (e.g, `langchain-community`)
-
-If you try to import it from `langchain`, the import will keep on working, but will raise a deprecation warning. The warning will provide a replacement import statement.
-
-```python
-python -c "from langchain.document_loaders.markdown import UnstructuredMarkdownLoader"
-
-```
-
-```python
-LangChainDeprecationWarning: Importing UnstructuredMarkdownLoader from langchain.document_loaders is deprecated. Please replace deprecated imports:
-
->> from langchain.document_loaders import UnstructuredMarkdownLoader
-
-with new imports of:
-
->> from langchain_community.document_loaders import UnstructuredMarkdownLoader
-```
-
-We will continue supporting the imports in `langchain` until release 0.4 as long as the relevant package where the code lives is installed. (e.g., as long as `langchain_community` is installed.)
-
-However, we advise for users to not rely on these imports and instead migrate to the new imports. To help with this process, we’re releasing a migration script via the LangChain CLI. See further instructions in migration guide.
-
-1. Code that has better alternatives available and will eventually be removed, so there’s only a single way to do things. (e.g., `predict_messages` method in ChatModels has been deprecated in favor of `invoke`).
-
-Many of these were marked for removal in 0.2. We have bumped the removal to 0.3.

+       "'While Scrum has its potential cons and challenges, many organizations have successfully embraced and implemented this project management framework to great effect. The cons mentioned above can be mitigated or overcome with proper training, support, and a commitment to continuous improvement. It is also important to note that not all cons may be applicable to every organization or project.\\n\\nFor example, while Scrum may be complex initially, with proper training and guidance, teams can quickly grasp the concepts and practices. The lack of predictability can be mitigated by implementing techniques such as velocity tracking and release planning. The limited documentation can be addressed by maintaining a balance between lightweight documentation and clear communication among team members. The dependency on team collaboration can be improved through effective communication channels and regular team-building activities.\\n\\nScrum can be scaled and adapted to larger projects by using frameworks like Scrum of Scrums or LeSS (Large Scale Scrum). Concerns about speed versus quality can be addressed by incorporating quality assurance practices, such as continuous integration and automated testing, into the Scrum process. Scope creep can be managed by having a well-defined and prioritized product backlog, and a strong product owner can be developed through training and mentorship.\\n\\nResistance to change can be overcome by providing proper education and communication to stakeholders and involving them in the decision-making process. Ultimately, the cons of Scrum can be seen as opportunities for growth and improvement, and with the right mindset and support, they can be effectively managed.\\n\\nIn conclusion, while Scrum may have its challenges and potential cons, the benefits and advantages it offers in terms of collaboration, flexibility, adaptability, transparency, and customer satisfaction make it a widely adopted and successful project management framework. With proper implementation and continuous improvement, organizations can leverage Scrum to drive innovation, efficiency, and project success.'"

+# LangChain Expression Language (LCEL)
+
+LangChain Expression Language, or LCEL, is a declarative way to easily compose chains together.
+LCEL was designed from day 1 to **support putting prototypes in production, with no code changes**, from the simplest “prompt + LLM” chain to the most complex chains (we’ve seen folks successfully run LCEL chains with 100s of steps in production). To highlight a few of the reasons you might want to use LCEL:
+
+[**First-class streaming support**](/docs/expression_language/streaming)
+When you build your chains with LCEL you get the best possible time-to-first-token (time elapsed until the first chunk of output comes out). For some chains this means eg. we stream tokens straight from an LLM to a streaming output parser, and you get back parsed, incremental chunks of output at the same rate as the LLM provider outputs the raw tokens.
+
+[**Async support**](/docs/expression_language/interface)
+Any chain built with LCEL can be called both with the synchronous API (eg. in your Jupyter notebook while prototyping) as well as with the asynchronous API (eg. in a [LangServe](/docs/langsmith) server). This enables using the same code for prototypes and in production, with great performance, and the ability to handle many concurrent requests in the same server.
+
+[**Optimized parallel execution**](/docs/expression_language/primitives/parallel)
+Whenever your LCEL chains have steps that can be executed in parallel (eg if you fetch documents from multiple retrievers) we automatically do it, both in the sync and the async interfaces, for the smallest possible latency.
+
+[**Retries and fallbacks**](/docs/guides/productionization/fallbacks)
+Configure retries and fallbacks for any part of your LCEL chain. This is a great way to make your chains more reliable at scale. We’re currently working on adding streaming support for retries/fallbacks, so you can get the added reliability without any latency cost.
+
+[**Access intermediate results**](/docs/expression_language/interface#async-stream-events-beta)
+For more complex chains it’s often very useful to access the results of intermediate steps even before the final output is produced. This can be used to let end-users know something is happening, or even just to debug your chain. You can stream intermediate results, and it’s available on every [LangServe](/docs/langserve) server.
+
+[**Input and output schemas**](/docs/expression_language/interface#input-schema)
+Input and output schemas give every LCEL chain Pydantic and JSONSchema schemas inferred from the structure of your chain. This can be used for validation of inputs and outputs, and is an integral part of LangServe.
+
+[**Seamless LangSmith tracing**](/docs/langsmith)
+As your chains get more and more complex, it becomes increasingly important to understand what exactly is happening at every step.
+With LCEL, **all** steps are automatically logged to [LangSmith](/docs/langsmith/) for maximum observability and debuggability.
+
+[**Seamless LangServe deployment**](/docs/langserve)
+Any chain created with LCEL can be easily deployed using [LangServe](/docs/langserve).
