主张神经符号人工智能（NESY）断言，将深度学习与象征性推理相结合将导致AI更强大，而不是本身。像深度学习一样成功，人们普遍认为，即使我们最好的深度学习系统也不是很擅长抽象推理。而且，由于推理与语言密不可分，因此具有直觉的意义，即自然语言处理（NLP）将成为NESY特别适合的候选人。我们对实施NLP实施NESY的研究进行了结构化审查，目的是回答Nesy是否确实符合其承诺的问题：推理，分布概括，解释性，学习和从小数据的可转让性以及新的推理到新的域。我们研究了知识表示的影响，例如规则和语义网络，语言结构和关系结构，以及隐式或明确的推理是否有助于更高的承诺分数。我们发现，将逻辑编译到神经网络中的系统会导致满足最NESY的目标，而其他因素（例如知识表示或神经体系结构的类型）与实现目标没有明显的相关性。我们发现在推理的定义方式上，特别是与人类级别的推理有关的许多差异，这会影响有关模型架构的决策并推动结论，这些结论在整个研究中并不总是一致的。因此，我们倡导采取更加有条不紊的方法来应用人类推理的理论以及适当的基准的发展，我们希望这可以更好地理解该领域的进步。我们在GitHub上提供数据和代码以进行进一步分析。

The management of cattle over a huge area is still a challenging problem in the farming sector. With evolution in technology, Unmanned aerial vehicles (UAVs) with consumer level digital cameras are becoming a popular alternative to manual animal censuses for livestock estimation since they are less risky and expensive.This paper evaluated and compared the cutting-edge object detection algorithms, YOLOv7,RetinaNet with ResNet50 backbone, RetinaNet with EfficientNet and mask RCNN. It aims to improve the occlusion problem that is to detect hidden cattle from a huge dataset captured by drones using deep learning algorithms for accurate cattle detection. Experimental results showed YOLOv7 was superior with precision of 0.612 when compared to the other two algorithms. The proposed method proved superior to the usual competing algorithms for cow face detection, especially in very difficult cases.

Legal contracts, such as employment or lease agreements, are important documents as they govern the obligations and entitlements of the various contracting parties. However, these documents are typically long and written in legalese resulting in lots of manual hours spent in understanding them. In this paper, we address the task of summarizing legal contracts for each of the contracting parties, to enable faster reviewing and improved understanding of them. Specifically, we collect a dataset consisting of pairwise importance comparison annotations by legal experts for ~293K sentence pairs from lease agreements. We propose a novel extractive summarization system to automatically produce a summary consisting of the most important obligations, entitlements, and prohibitions in a contract. It consists of two modules: (1) a content categorize to identify sentences containing each of the categories (i.e., obligation, entitlement, and prohibition) for a party, and (2) an importance ranker to compare the importance among sentences of each category for a party to obtain a ranked list. The final summary is produced by selecting the most important sentences of a category for each of the parties. We demonstrate the effectiveness of our proposed system by comparing it against several text ranking baselines via automatic and human evaluation.

We present POTATO, the Portable text annotation tool, a free, fully open-sourced annotation system that 1) supports labeling many types of text and multimodal data; 2) offers easy-to-configure features to maximize the productivity of both deployers and annotators (convenient templates for common ML/NLP tasks, active learning, keypress shortcuts, keyword highlights, tooltips); and 3) supports a high degree of customization (editable UI, inserting pre-screening questions, attention and qualification tests). Experiments over two annotation tasks suggest that POTATO improves labeling speed through its specially-designed productivity features, especially for long documents and complex tasks. POTATO is available at https://github.com/davidjurgens/potato and will continue to be updated.

Athletes routinely undergo fitness evaluations to evaluate their training progress. Typically, these evaluations require a trained professional who utilizes specialized equipment like force plates. For the assessment, athletes perform drop and squat jumps, and key variables are measured, e.g. velocity, flight time, and time to stabilization, to name a few. However, amateur athletes may not have access to professionals or equipment that can provide these assessments. Here, we investigate the feasibility of estimating key variables using video recordings. We focus on jump velocity as a starting point because it is highly correlated with other key variables and is important for determining posture and lower-limb capacity. We find that velocity can be estimated with a high degree of precision across a range of athletes, with an average R-value of 0.71 (SD = 0.06).

Large language models (LLMs) have been shown to be able to perform new tasks based on a few demonstrations or natural language instructions. While these capabilities have led to widespread adoption, most LLMs are developed by resource-rich organizations and are frequently kept from the public. As a step towards democratizing this powerful technology, we present BLOOM, a 176B-parameter open-access language model designed and built thanks to a collaboration of hundreds of researchers. BLOOM is a decoder-only Transformer language model that was trained on the ROOTS corpus, a dataset comprising hundreds of sources in 46 natural and 13 programming languages (59 in total). We find that BLOOM achieves competitive performance on a wide variety of benchmarks, with stronger results after undergoing multitask prompted finetuning. To facilitate future research and applications using LLMs, we publicly release our models and code under the Responsible AI License.

We consider the problem of multi-agent navigation and collision avoidance when observations are limited to the local neighborhood of each agent. We propose InforMARL, a novel architecture for multi-agent reinforcement learning (MARL) which uses local information intelligently to compute paths for all the agents in a decentralized manner. Specifically, InforMARL aggregates information about the local neighborhood of agents for both the actor and the critic using a graph neural network and can be used in conjunction with any standard MARL algorithm. We show that (1) in training, InforMARL has better sample efficiency and performance than baseline approaches, despite using less information, and (2) in testing, it scales well to environments with arbitrary numbers of agents and obstacles.

分散的学习算法可以通过在不同设备和位置生成的大型分布式数据集对深度学习模型进行培训，而无需中央服务器。在实际情况下，分布式数据集可以在整个代理之间具有显着不同的数据分布。当前的最新分散算法主要假设数据分布是独立且分布相同的（IID）。本文的重点是用最小的计算和内存开销来改善非IID数据分布的分散学习。我们提出了邻居梯度聚类（NGC），这是一种新型的分散学习算法，使用自我和交叉梯度信息修改每个代理的局部梯度。特别是，所提出的方法用自级的加权平均值，模型变化的跨梯度（接收到的邻居模型参数相对于本地数据集的衍生物）和数据变化，将模型的局部梯度取代了模型变化的均值平均值交叉梯度（相对于其邻居数据集的本地模型的衍生物）。此外，我们提出了compngc，这是NGC的压缩版本，通过压缩交叉梯度将通信开销降低了$ 32 \ times $。我们证明了所提出的技术在各种模型体系结构和图形拓扑上采样的非IID数据分布上提出的技术的经验收敛性和效率。我们的实验表明，NGC和COMPNGC的表现优于现有的最先进的（SOTA）去中心化学习算法，而不是非IID数据的$ 1-5 \％$，其计算和内存需求明显降低。此外，我们还表明，所提出的NGC方法的表现优于$ 5-40 \％$，而没有其他交流。

产品的属性值是任何电子商务平台中必不可少的组件。属性值提取（AVE）涉及从其标题或描述中提取产品的属性及其值。在本文中，我们建议使用生成框架解决AVE任务。我们通过将AVE任务作为生成问题制定，即基于单词序列和基于位置的生成范式，即基于单词序列和位置序列。我们在两个数据集上进行实验，在该数据集中生成方法获得了新的最新结果。这表明我们可以将建议的框架用于AVE任务，而无需其他标记或特定于任务的模型设计。

我们使用对单个的，相同的$ d $维状态的相同副本进行的测量来研究量子断层扫描和阴影断层扫描的问题。我们首先因Haah等人而重新审视已知的下限。 （2017年）在痕量距离上具有准确性$ \ epsilon $的量子断层扫描，当测量选择与先前观察到的结果无关（即它们是非适应性的）时。我们简要地证明了这一结果。当学习者使用具有恒定结果数量的测量值时，这会导致更强的下限。特别是，这严格确定了民间传说的最佳性``Pauli phymography''算法的样本复杂性。我们还得出了$ \ omega（r^2 d/\ epsilon^2）$和$ \ omega（r^2 d/\ epsilon^2）的新颖界限（ R^2 d^2/\ epsilon^2）$用于学习排名$ r $状态，分别使用任意和恒定的结果测量，在非适应性情况下。除了样本复杂性，对于学习量子的实际意义，是一种实际意义的资源状态是算法使用的不同测量值的数量。我们将下限扩展到学习者从固定的$ \ exp（o（d））$测量的情况下进行自适应测量的情况。这特别意味着适应性。没有使用可有效实现的单拷贝测量结果给我们任何优势。在目标是预测给定的可观察到给定序列的期望值的情况下，我们还获得了类似的界限，该任务被称为阴影层析成像。在适应性的情况下单拷贝测量可通过多项式大小的电路实现，我们证明了基于计算给定可观察物的样本平均值的直接策略是最佳的。
