-**Abstract:** While recent language models have the ability to take long contexts as input,
-relatively little is known about how well they use longer context. We analyze
-the performance of language models on two tasks that require identifying
-relevant information in their input contexts: multi-document question answering
-and key-value retrieval. We find that performance can degrade significantly
-when changing the position of relevant information, indicating that current
-language models do not robustly make use of information in long input contexts.
-In particular, we observe that performance is often highest when relevant
-information occurs at the beginning or end of the input context, and
-significantly degrades when models must access relevant information in the
-middle of long contexts, even for explicitly long-context models. Our analysis
-provides a better understanding of how language models use their input context
-and provides new evaluation protocols for future long-context language models.

+
+**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.

+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:** Despite the remarkable ability of large language models (LMs) to comprehend
-and generate language, they have a tendency to hallucinate and create factually
-inaccurate output. Augmenting LMs by retrieving information from external
-knowledge resources is one promising solution. Most existing retrieval
-augmented LMs employ a retrieve-and-generate setup that only retrieves
-information once based on the input. This is limiting, however, in more general
-scenarios involving generation of long texts, where continually gathering
-information throughout generation is essential. In this work, we provide a
-generalized view of active retrieval augmented generation, methods that
-actively decide when and what to retrieve across the course of the generation.
-We propose Forward-Looking Active REtrieval augmented generation (FLARE), a
-generic method which iteratively uses a prediction of the upcoming sentence to
-anticipate future content, which is then utilized as a query to retrieve
-relevant documents to regenerate the sentence if it contains low-confidence
-tokens. We test FLARE along with baselines comprehensively over 4 long-form
-knowledge-intensive generation tasks/datasets. FLARE achieves superior or
-competitive performance on all tasks, demonstrating the effectiveness of our
-method. Code and datasets are available at https://github.com/jzbjyb/FLARE.

-**Abstract:** As AI systems become more capable, we would like to enlist their help to
-supervise other AIs. We experiment with methods for training a harmless AI
-assistant through self-improvement, without any human labels identifying
-harmful outputs. The only human oversight is provided through a list of rules
-or principles, and so we refer to the method as 'Constitutional AI'. The
-process involves both a supervised learning and a reinforcement learning phase.
-In the supervised phase we sample from an initial model, then generate
-self-critiques and revisions, and then finetune the original model on revised
-responses. In the RL phase, we sample from the finetuned model, use a model to
-evaluate which of the two samples is better, and then train a preference model
-from this dataset of AI preferences. We then train with RL using the preference
-model as the reward signal, i.e. we use 'RL from AI Feedback' (RLAIF). As a
-result we are able to train a harmless but non-evasive AI assistant that
-engages with harmful queries by explaining its objections to them. Both the SL
-and RL methods can leverage chain-of-thought style reasoning to improve the
-human-judged performance and transparency of AI decision making. These methods
-make it possible to control AI behavior more precisely and with far fewer human
-labels.
