在对比的表示学习中，训练数据表示，使得即使在通过增强的图像改变时，它也可以对图像实例进行分类。然而，根据数据集，一些增强可以损坏超出识别的图像的信息，并且这种增强可以导致折叠表示。我们通过将随机编码过程正式化，其中通过增强的数据损坏与由编码器保留的信息之间存在脱疣，对该问题提出了部分解决方案。我们展示了基于此框架的InfoMax目标，我们可以学习增强的数据依赖分布，以避免表示的崩溃。

The task we consider is portfolio construction in a speculative market, a fundamental problem in modern finance. While various empirical works now exist to explore deep learning in finance, the theory side is almost non-existent. In this work, we focus on developing a theoretical framework for understanding the use of data augmentation for deep-learning-based approaches to quantitative finance. The proposed theory clarifies the role and necessity of data augmentation for finance; moreover, our theory implies that a simple algorithm of injecting a random noise of strength $\sqrt{|r_{t-1}|}$ to the observed return $r_{t}$ is better than not injecting any noise and a few other financially irrelevant data augmentation techniques.

Utilizing the latest advances in Artificial Intelligence (AI), the computer vision community is now witnessing an unprecedented evolution in all kinds of perception tasks, particularly in object detection. Based on multiple spatially separated perception nodes, Cooperative Perception (CP) has emerged to significantly advance the perception of automated driving. However, current cooperative object detection methods mainly focus on ego-vehicle efficiency without considering the practical issues of system-wide costs. In this paper, we introduce VINet, a unified deep learning-based CP network for scalable, lightweight, and heterogeneous cooperative 3D object detection. VINet is the first CP method designed from the standpoint of large-scale system-level implementation and can be divided into three main phases: 1) Global Pre-Processing and Lightweight Feature Extraction which prepare the data into global style and extract features for cooperation in a lightweight manner; 2) Two-Stream Fusion which fuses the features from scalable and heterogeneous perception nodes; and 3) Central Feature Backbone and 3D Detection Head which further process the fused features and generate cooperative detection results. A cooperative perception platform is designed and developed for CP dataset acquisition and several baselines are compared during the experiments. The experimental analysis shows that VINet can achieve remarkable improvements for pedestrians and cars with 2x less system-wide computational costs and 12x less system-wide communicational costs.

Telework "avatar work," in which people with disabilities can engage in physical work such as customer service, is being implemented in society. In order to enable avatar work in a variety of occupations, we propose a mobile sales system using a mobile frozen drink machine and an avatar robot "OriHime", focusing on mobile customer service like peddling. The effect of the peddling by the system on the customers are examined based on the results of video annotation.

Our team, Hibikino-Musashi@Home (the shortened name is HMA), was founded in 2010. It is based in the Kitakyushu Science and Research Park, Japan. We have participated in the RoboCup@Home Japan open competition open platform league every year since 2010. Moreover, we participated in the RoboCup 2017 Nagoya as open platform league and domestic standard platform league teams. Currently, the Hibikino-Musashi@Home team has 20 members from seven different laboratories based in the Kyushu Institute of Technology. In this paper, we introduce the activities of our team and the technologies.

针对目标的对话任务的先前研究缺乏关键观念，该观念在以目标为导向的人工智能代理的背景下进行了深入研究。在这项研究中，我们提出了目标引导的开放域对话计划（TGCP）任务的任务，以评估神经对话代理是否具有目标对话计划的能力。使用TGCP任务，我们研究了现有检索模型和最新强生成模型的对话计划能力。实验结果揭示了当前技术面临的挑战。

感知环境是实现合作驾驶自动化（CDA）的最基本关键之一，该关键被认为是解决当代运输系统的安全性，流动性和可持续性问题的革命性解决方案。尽管目前在计算机视觉的物体感知领域正在发生前所未有的进化，但由于不可避免的物理遮挡和单辆车的接受程度有限，最先进的感知方法仍在与复杂的现实世界流量环境中挣扎系统。基于多个空间分离的感知节点，合作感知（CP）诞生是为了解锁驱动自动化的感知瓶颈。在本文中，我们全面审查和分析了CP的研究进度，据我们所知，这是第一次提出统一的CP框架。审查了基于不同类型的传感器的CP系统的体系结构和分类学，以显示对CP系统的工作流程和不同结构的高级描述。对节点结构，传感器模式和融合方案进行了审查和分析，并使用全面的文献进行了详细的解释。提出了分层CP框架，然后对现有数据集和模拟器进行审查，以勾勒出CP的整体景观。讨论重点介绍了当前的机会，开放挑战和预期的未来趋势。

游戏中的学习理论在AI社区中很突出，这是由多个不断上升的应用程序（例如多代理增强学习和生成对抗性网络）的动机。我们提出了突变驱动的乘法更新（M2WU），以在两人零和零正常形式游戏中学习平衡，并证明它在全面和嘈杂的信息反馈设置中都表现出了最后的题融合属性。在全信息反馈设置中，玩家观察了实用程序功能的确切梯度向量。另一方面，在嘈杂的信息反馈设置中，他们只能观察到嘈杂的梯度向量。现有的算法，包括众所周知的乘法权重更新（MWU）和乐观的MWU（OMWU）算法，未能收敛到具有嘈杂的信息反馈的NASH平衡。相反，在两个反馈设置中，M2WU表现出最后的近期收敛到NASH平衡附近的固定点。然后，我们证明它通过迭代地适应突变项来收敛到精确的NASH平衡。我们从经验上确认，M2WU在可剥削性和收敛速率方面胜过MWU和OMWU。

避免产生与先前环境相矛盾的响应是对话响应产生的重大挑战。一种可行的方法是后处理，例如从最终的n-最佳响应列表中滤除矛盾的响应。在这种情况下，n-最佳列表的质量极大地影响了矛盾的发生，因为最终响应是从该最佳列表中选择的。这项研究定量地分析了使用N最佳列表的一致性对神经反应产生模型的上下文矛盾意识。特别是，我们将极性问题用作简洁和定量分析的刺激输入。我们的测试说明了最近的神经反应产生模型和方法的矛盾意识，然后讨论了它们的性质和局限性。

我们介绍了Realtime QA，这是一个动态的问答（QA）平台，该平台宣布问题并定期评估系统（此版本每周）。实时质量检查询问当前世界，质量检查系统需要回答有关新事件或信息的问题。因此，它挑战了QA数据集中的静态，常规假设，并追求瞬时应用。我们在包括GPT-3和T5在内的大型语言模型上建立了强大的基线模型。我们的基准是一项持续的努力，该初步报告在过去一个月中提出了实时评估结果。我们的实验结果表明，GPT-3通常可以根据新的退休文档正确更新其生成结果，从而突出了最新信息检索的重要性。尽管如此，我们发现GPT-3倾向于在检索文件时返回过时的答案，这些文件没有提供足够的信息来找到答案。这表明了未来研究的重要途径：开放式域质量检查系统是否可以确定无法回答的案例，并与用户甚至检索模块进行通信以修改检索结果？我们希望实时质量检查能够刺激问题答案及其他问题的瞬时应用。
