从预训练的语言模型中进行的引导已被证明是用于建立基础视觉模型（VLM）的有效方法，例如图像字幕或视觉问题的答案。但是，很难用它来使模型符合用户的理由来获得特定答案。为了引起和加强常识性原因，我们提出了一个迭代采样和调整范式，称为Illume，执行以下循环：给定图像问题提示提示，VLM采样了多个候选人，并通过人类评论家通过偏好提供最小的反馈。选择，用于微调。该循环增加了训练数据，并逐渐雕刻出VLM的合理化功能。我们的详尽实验表明，Illume在使用较少的培训数据的同时，仅需要最少的反馈，与标准监督的微调竞争。

基础模型由于在广泛的下游应用中的有效性而受到了很多关注。尽管在体系结构方面存在很大的融合，但大多数审慎的模型通常仍用于特定任务或模式。在这项工作中，我们建议将语言模型用作各种基础模型的通用接口。一系列预处理的编码者感知到了多种方式（例如视觉和语言），并与扮演通用任务层角色的语言模型对接。我们提出了一个半伴侣的语言建模目标，以共同确定界面和模块化编码器。我们从因果关系和非因果建模中涵盖了优势和能力，从而结合了两个世界的最佳状态。具体而言，所提出的方法不仅从因果语言建模中继承了内在学习和开放式生成的能力，而且由于双向编码器而有利于填补。更重要的是，我们的方法无缝地解锁了上述功能的组合，例如，通过填充编码器启用了文本学习或指导。各种仅语言和视觉语言基准的实验结果表明，我们的模型表现优于或与鉴定，零弹性概括和几乎没有的学习的专业模型竞争。

Natural language explanations promise to offer intuitively understandable explanations of a neural network's decision process in complex vision-language tasks, as pursued in recent VL-NLE models. While current models offer impressive performance on task accuracy and explanation plausibility, they suffer from a range of issues: Some models feature a modular design where the explanation generation module is poorly integrated with a separate module for task-answer prediction, employ backbone models trained on limited sets of tasks, or incorporate ad hoc solutions to increase performance on single datasets. We propose to evade these limitations by applying recent advances in large-scale multi-task pretraining of generative Transformer models to the problem of VL-NLE tasks. Our approach outperforms recent models by a large margin, with human annotators preferring the generated explanations over the ground truth in two out of three evaluated datasets. As a novel challenge in VL-NLE research, we propose the problem of multi-task VL-NLE and show that jointly training on multiple tasks can increase the explanation quality. We discuss the ethical implications of high-quality NLE generation and other issues in recent VL-NLE research.

Reasoning, as an essential ability for complex problem-solving, can provide back-end support for various real-world applications, such as medical diagnosis, negotiation, etc. This paper provides a comprehensive survey of cutting-edge research on reasoning with language model prompting. We introduce research works with comparisons and summaries and provide systematic resources to help beginners. We also discuss the potential reasons for emerging such reasoning abilities and highlight future research directions.

大规模预制速度迅速成为视觉语言（VL）建模中的规范。然而，普遍的VL方法受标记数据的要求和复杂的多步预介质目标的要求受限。我们呈现Magma - 使用基于适配器的FineTuning使用额外的方式增强生成语言模型的简单方法。在冻结的情况下，我们培训一系列VL模型，从视觉和文本输入的任意组合自动生成文本。使用单一语言建模目的，预先预测完全结束于结束，与先前的方法相比，简化优化。重要的是，在培训期间，语言模型权重保持不变，允许从语言预磨练转移百科全书知识和内心的学习能力。 Magma在开放式生成任务上冻结的岩浆，实现了最先进的状态，结果在Okvqa基准和竞争结果上的一系列其他流行的VL基准测试中，同时预先训练用于培训SIMVLM的样本数量的0.2％。

Language models (LMs) have demonstrated remarkable performance on downstream tasks, using in-context exemplars or human instructions. Recent works have shown that chain-of-thought (CoT) prompting can elicit models to solve complex reasoning tasks, step-by-step. However, the efficacy of prompt-based CoT methods is restricted to very large LMs such as GPT-3 (175B), thus limiting deployability. In this paper, we revisit the fine-tuning approach to enable complex reasoning in smaller LMs, optimized to efficiently perform a specific task. We propose Fine-tune-CoT, a method that leverages the capabilities of very large LMs to generate reasoning samples and teach smaller models via fine-tuning. We evaluate our method on publicly available LMs across a wide range of complex tasks and model sizes. We find that Fine-tune-CoT enables substantial reasoning capability in small models, whereas previous prompt-based baselines exhibit near-random performance. Student models can even outperform the teacher in some tasks while reducing model size requirements by several orders of magnitude. We conduct extensive ablations and sample studies to understand the reasoning capabilities of student models. We also identify several important nuances that have been overlooked in concurrent fine-tuning works on CoT and address them in our analysis.

在回答问题时，人类会利用跨不同模式可用的信息来综合一致，完整的思想链（COT）。在深度学习模型（例如大规模语言模型）的情况下，这个过程通常是黑匣子。最近，科学问题基准已用于诊断AI系统的多跳推理能力和解释性。但是，现有数据集无法为答案提供注释，或仅限于仅文本模式，小尺度和有限的域多样性。为此，我们介绍了科学问题答案（SQA），这是一个新的基准，由〜21k的多模式多种选择问题组成，其中包含各种科学主题和答案的注释，并提供相应的讲座和解释。我们进一步设计语言模型，以学习将讲座和解释作为思想链（COT），以模仿回答SQA问题时的多跳上推理过程。 SQA在语言模型中展示了COT的实用性，因为COT将问题的答案绩效提高了1.20％的GPT-3和3.99％的unifiedqa。我们还探索了模型的上限，以通过喂食输入中的那些来利用解释；我们观察到它将GPT-3的少量性能提高了18.96％。我们的分析进一步表明，与人类类似的语言模型受益于解释，从较少的数据中学习并仅使用40％的数据实现相同的性能。

视频问题回答（VideoQA）是一项复杂的任务，需要多种模式数据进行培训。但是，对视频的问题和答案的手动注释是乏味的，禁止可扩展性。为了解决这个问题，最近的方法考虑了零拍设置，而无需手动注释视觉问题。特别是，一种有前途的方法调整了在网络级文本数据中预测的冻结自回归语言模型，以适应多模式输入。相比之下，我们在这里建立在冷冻双向语言模型（BILM）的基础上，并表明这种方法为零拍出的VideoQA提供了更强大，更便宜的替代方案。特别是（i）我们使用轻型训练模块将视觉输入与冷冻的BILM结合在一起，（ii）我们使用Web-Scrafe Multi-Mododal数据训练此类模块，最后（iii）我们通过掩盖语言执行零声录像带推断建模，其中蒙版文本是给定问题的答案。我们提出的方法Frozenbilm在零摄影的视频中的表现优于最高的，包括LSMDC-FIB，包括LSMDC-FIB，IVQA，MSRVTT-QA，MSVD-QA，ActivityNet-QA，TGIF-FRAMEQA，TGIF-FRAMEQA，，TGIF-FRAMEQA，，TGIF-FRAMEQA，，，MSRVTT-QA，MSRVTT-QA，MSRVTT-QA，MSRVTT-QA，MSRVTT-QA，，均优于最新技术。 How2QA和TVQA。它还在几次且完全监督的环境中展示了竞争性能。我们的代码和模型将在https://antoyang.github.io/frozenbilm.html上公开提供。

基于知识的视觉问题答案（VQA）涉及回答图像中不存在外部知识的问题。现有方法首先从外部资源中检索知识，然后通过所选知识，输入图像和答案预测的问题进行理性。但是，这种两步方法可能导致不匹配，可能会限制VQA性能。例如，检索到的知识可能与该问题无关紧要，并且在推理过程中重新安装的知识特征可能会偏离其在知识库中的最初含义（KB）。为了应对这一挑战，我们提出了PICA，这是一种简单而有效的方法，该方法通过使用图像字幕提示GPT3用于基于知识的VQA。受GPT-3在知识检索和问题答案中的力量的启发，而不是像以前的工作那样使用结构化的KB，而是将GPT-3视为一种隐式和非结构化的KB，可以共同获取和处理相关的知识。具体来说，我们首先将图像转换为GPT-3可以理解的标题（或标签），然后通过提供一些文字中的VQA示例来调整GPT-3以几个弹射方式解决VQA任务。我们通过仔细研究进一步提高绩效：（i）哪种文本格式最能描述图像内容，以及（ii）如何更好地选择和使用中文示例。 PICA解锁了GPT-3用于多模式任务的首次使用。通过仅使用16个示例，PICA超过了OK-VQA数据集上的绝对+8.6点。我们还在VQAV2上基准了PICA，PICA还显示出不错的表现。

Large language models (LLMs) have demonstrated excellent zero-shot generalization to new language tasks. However, effective utilization of LLMs for zero-shot visual question-answering (VQA) remains challenging, primarily due to the modality disconnection and task disconnection between LLM and VQA task. End-to-end training on vision and language data may bridge the disconnections, but is inflexible and computationally expensive. To address this issue, we propose \emph{Img2Prompt}, a plug-and-play module that provides the prompts that can bridge the aforementioned modality and task disconnections, so that LLMs can perform zero-shot VQA tasks without end-to-end training. In order to provide such prompts, we further employ LLM-agnostic models to provide prompts that can describe image content and self-constructed question-answer pairs, which can effectively guide LLM to perform zero-shot VQA tasks. Img2Prompt offers the following benefits: 1) It can flexibly work with various LLMs to perform VQA. 2)~Without the needing of end-to-end training, it significantly reduces the cost of deploying LLM for zero-shot VQA tasks. 3) It achieves comparable or better performance than methods relying on end-to-end training. For example, we outperform Flamingo~\cite{Deepmind:Flamingo2022} by 5.6\% on VQAv2. On the challenging A-OKVQA dataset, our method even outperforms few-shot methods by as much as 20\%.

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.

大型语言模型在零拍摄设置中的许多自然语言处理（NLP）任务中表现出令人印象深刻的性能。我们询问这些模型是否展示了致辞语言 - NLP应用的关键组成部分 - 通过评估四个偶数基准的模型。我们发现大型语言模型的令人印象深刻的零射击性能主要是由于我们的基准测试中的数据集偏差。我们还表明，零拍摄性能对基准的超参数和相似性敏感到预训练数据集。此外，当在几次拍摄设置中评估模型时，我们没有观察大量改进。最后，与以前的工作相比，我们发现利用明确的致辞知识并没有产生重大改善。

在过去的几年中，在文化遗产领域中使用深度学习和计算机视觉在文化遗产领域变得非常相关，其中包括有关音频智能指南，互动博物馆和增强现实的大量应用。所有这些技术都需要大量数据才能有效工作并对用户有用。在艺术品的背景下，专家在昂贵且耗时的过程中注释了此类数据。特别是，对于每件艺术品，必须收集艺术品和描述表的图像，以执行诸如视觉问题回答之类的常见任务。在本文中，我们提出了一种视觉问题回答的方法，该方法允许在运行时生成一个描述表，该表可用于回答有关艺术品的视觉和上下文问题，从而完全避免了图像和注释过程。为此，我们研究了使用GPT-3来生成描述用于艺术品，以分析通过字幕指标分析生成的描述的质量。最后，我们评估了视觉问答答案和字幕任务的性能。

在维持预审预定序列模型的灵活性的同时，是否有利于常识性推理，这仍然是一个悬而未决的问题。为了调查这个问题，我们开发了生成的知识提示，该提示包括从语言模型中生成知识，然后在回答问题时提供知识作为附加输入。我们的方法不需要特定于任务的监督知识集成或访问结构化的知识库，但它可以提高四个常识性推理任务上的大规模，最先进的模型的性能，从而实现最先进-ART结果取决于数值常识（NumerSense），通用常识性（Commonsenseqa 2.0）和科学常识（QASC）基准。产生的知识促使大型语言模型是灵活的外部知识来源，以改善常识性推理。我们的代码可从https://github.com/liujch1998/gkp获得

We present Answer-Me, a task-aware multi-task framework which unifies a variety of question answering tasks, such as, visual question answering, visual entailment, visual reasoning. In contrast to previous works using contrastive or generative captioning training, we propose a novel and simple recipe to pre-train a vision-language joint model, which is multi-task as well. The pre-training uses only noisy image captioning data, and is formulated to use the entire architecture end-to-end with both a strong language encoder and decoder. Our results show state-of-the-art performance, zero-shot generalization, robustness to forgetting, and competitive single-task results across a variety of question answering tasks. Our multi-task mixture training learns from tasks of various question intents and thus generalizes better, including on zero-shot vision-language tasks. We conduct experiments in the challenging multi-task and open-vocabulary settings and across a variety of datasets and tasks, such as VQA2.0, SNLI-VE, NLVR2, GQA. We observe that the proposed approach is able to generalize to unseen tasks and that more diverse mixtures lead to higher accuracy in both known and novel tasks.

本文探讨了提高语言模型的零次学习能力的简单方法。我们表明，指令调整 - 通过对说明书中所述的任务集合微调语言模型 - 大幅提升零射门上看不见任务中的表现。我们采取预训练的语言模型和指令调整它通过自然语言指令模板语言表达了60NLP任务137B参数。我们评估这种指令调整模型，我们称之为FLAN，在看不见的任务类型。FLAN显着改善其未修饰的对应的性能和超过25的20个任务，我们评估零射门175BGPT-3。FLAN甚至GPT-3通过在安利，RTE，BoolQ，AI2-ARC，OpenbookQA和StoryCloze大比分胜过几拍。消融研究显示任务和模型的规模，这个数字是指令调整取得成功的关键组成部分。

Recent work has shown that fine-tuning large pre-trained language models on a collection of tasks described via instructions, a.k.a. instruction-tuning, improves their zero and few-shot generalization to unseen tasks. However, there is a limited understanding of the performance trade-offs of different decisions made during the instruction-tuning process. These decisions include the scale and diversity of the instruction-tuning benchmark, different task sampling strategies, fine-tuning with and without demonstrations, training using specialized datasets for reasoning and dialogue, and finally, the fine-tuning objectives themselves. In this paper, we characterize the effect of instruction-tuning decisions on downstream task performance when scaling both model and benchmark sizes. To this end, we create OPT-IML Bench: a large benchmark for Instruction Meta-Learning (IML) of 2000 NLP tasks consolidated into task categories from 8 existing benchmarks, and prepare an evaluation framework to measure three types of model generalizations: to tasks from fully held-out categories, to held-out tasks from seen categories, and to held-out instances from seen tasks. Through the lens of this framework, we first present insights about instruction-tuning decisions as applied to OPT-30B and further exploit these insights to train OPT-IML 30B and 175B, which are instruction-tuned versions of OPT. OPT-IML demonstrates all three generalization abilities at both scales on four different evaluation benchmarks with diverse tasks and input formats -- PromptSource, FLAN, Super-NaturalInstructions, and UnifiedSKG. Not only does it significantly outperform OPT on all benchmarks but is also highly competitive with existing models fine-tuned on each specific benchmark. We release OPT-IML at both scales, together with the OPT-IML Bench evaluation framework.

最近的文本到图像匹配模型对大型图像和句子的大公司进行了对比学习。虽然这些模型可以提供用于匹配和随后的零拍任务的强大分数，但它们不能给出给定图像的标题。在这项工作中，我们重新利用这些模型来生成在推理时间的图像时生成描述性文本，而无需进一步的训练或调整步骤。这是通过将具有大语言模型的视觉语义模型组合，从两种网络级模型中的知识中获益。由受监督标题方法获得的标题的限制性较小。此外，作为零射击学习方法，它非常灵活，我们展示了执行图像算法的能力，其中输入可以是图像或文本，输出是句子。这使得新颖的高级视觉能力，例如比较两个图像或解决视觉类比测试。

Instruction tuning, a new learning paradigm that fine-tunes pre-trained language models on tasks specified through instructions, has shown promising zero-shot performance on various natural language processing tasks. However, it's still not explored for vision and multimodal tasks. In this work, we introduce MultiInstruct, the first multimodal instruction tuning benchmark dataset that consists of 47 diverse multimodal tasks covering 11 broad categories. Each task is designed at least with 5,000 instances (input-out pairs) from existing open-source datasets and 5 expert-written instructions. We take OFA as the base pre-trained model for multimodal instruction tuning, and to improve its performance, we explore multiple transfer learning strategies to leverage the large-scale Natural Instructions dataset. Experimental results demonstrate its strong zero-shot performance on various unseen multimodal tasks and the benefit of transfer learning from text-only instructions. We also design a new evaluation metric: Sensitivity, to evaluate how sensitive the model is to the variety of instructions. Our results indicate that the model is less sensitive to the varying instructions after finetuning on a diverse set of tasks and instructions for each task.

大型语言模型在各种任务上显示出令人印象深刻的几次结果。但是，当知识是此类结果的关键时，就像问题回答和事实检查之类的任务一样，似乎需要存储知识的大量参数计数。众所周知，检索增强模型可以在不需要多个参数的情况下在知识密集的任务上表现出色，但是目前尚不清楚它们是否在几个弹药设置中工作。在这项工作中，我们介绍了地图集，这是一个经过精心设计和预先训练的增强语言模型，能够通过很少的培训示例学习知识密集型任务。我们对包括MMLU，苏格兰短裙和归类等各种任务进行评估，并研究文档索引内容的影响，表明它可以很容易地进行更新。值得注意的是，在自然问题上仅使用64个示例在自然问题上达到超过42 \％的准确性，尽管参数少了50倍，但比540B参数模型的表现优于540b参数模型。
