在狭窄的空间中，基于传统层次自治系统的运动计划可能会导致映射，定位和控制噪声引起碰撞。此外，当无映射时，它将被禁用。为了解决这些问题，我们利用深厚的加强学习，可以证明可以有效地进行自我决策，从而在狭窄的空间中自探索而无需地图，同时避免碰撞。具体而言，基于我们的Ackermann-Steering矩形Zebrat机器人及其凉亭模拟器，我们建议矩形安全区域来表示状态并检测矩形形状的机器人的碰撞，以及无需精心制作的奖励功能，不需要增强功能。目的地信息。然后，我们在模拟的狭窄轨道中基准了五种增强学习算法，包括DDPG，DQN，SAC，PPO和PPO-DISCRETE。经过训练，良好的DDPG和DQN型号可以转移到三个全新的模拟轨道上，然后转移到三个现实世界中。

多亏了机器人技术的快速发展，机器人割草正在兴起，使人类摆脱了繁琐且耗时的景观工作。传统上，机器人割草被认为是“覆盖道路计划”问题，简化了将非凸障碍转换为凸障碍的障碍。此外，机器人的包围通常会扩张转换后的障碍物以避免碰撞。但是，当适用于机器人割草时，草坪上的障碍通常是非凸的，请想象一下草坪上的一个花园，这样上面提到的障碍物处理方法将填补某些凹面区域，以使机器人再也无法访问了它们，因此沿着草坪边缘产生不可避免的未切割区域，从而使景观的优雅降低并激发了返工。为了缩小草坪边缘周围的未切割区域，我们在此将问题重新构架为一个全新的问题，称其为“边缘覆盖路径计划”问题，该问题专门用于路径计划，以覆盖边缘。相应地，我们提出了两种计划方法，即“大小磁盘”和“滑动筷子”计划方法，以通过利用图像形态处理和计算几何技巧来解决问题。通过验证，我们提出的方法可以胜过传统的“逐一扩张”方法。

深度神经网络（DNN）由于其高度的感知，决策和控制而被广泛用于自主驾驶中。在诸如自动驾驶之类的安全至关重要系统中，实时执行感测和感知等任务对于车辆的安全至关重要，这需要应用程序的执行时间才能预测。但是，在DNN推断中观察到不可忽略的时间变化。当前的DNN推理研究要么忽略时间变化问题，要么依靠调度程序来处理它。当前的工作都没有解释DNN推理时间变化的根本原因。了解DNN推理的时间变化成为自动驾驶实时计划的基本挑战。在这项工作中，我们从六个角度分析了DNN推断的时间变化：数据，I/O，模型，运行时，硬件和端到端感知系统。在理解DNN推断的时间变化方面得出了六个见解。

老年人的跌倒检测是一些经过深入研究的问题，其中包括多种拟议的解决方案，包括可穿戴和不可磨损的技术。尽管现有技术的检测率很高，但由于需要佩戴设备和用户隐私问题，因此缺乏目标人群的采用。我们的论文提供了一种新颖的，不可磨损的，不受欢迎的和可扩展的解决方案，用于秋季检测，该解决方案部署在配备麦克风的自主移动机器人上。所提出的方法使用人们在房屋中记录的环境声音输入。我们专门针对浴室环境，因为它很容易跌落，并且在不危害用户隐私的情况下无法部署现有技术。目前的工作开发了一种基于变压器体系结构的解决方案，该解决方案从浴室中获取嘈杂的声音输入，并将其分为秋季/禁止类别，准确性为0.8673。此外，提出的方法可扩展到其他室内环境，除了浴室外，还适合在老年家庭，医院和康复设施中部署，而无需用户佩戴任何设备或不断受到传感器的“观察”。

由于深度学习模型通常包含数百万可培训的权重，因此对更有效的网络结构具有越来越高的存储空间和提高的运行时效率。修剪是最受欢迎的网络压缩技术之一。在本文中，我们提出了一种新颖的非结构化修剪管线，基于关注的同时稀疏结构和体重学习（ASWL）。与传统的频道和体重注意机制不同，ASWL提出了一种有效的算法来计算每层的层次引起的修剪比率，并且跟踪密度网络和稀疏网络的两种权重，以便修剪结构是同时从随机初始化的权重学习。我们在Mnist，CiFar10和Imagenet上的实验表明，与最先进的网络修剪方法相比，ASWL在准确性，修剪比率和操作效率方面取得了卓越的修剪。

The development of social media user stance detection and bot detection methods rely heavily on large-scale and high-quality benchmarks. However, in addition to low annotation quality, existing benchmarks generally have incomplete user relationships, suppressing graph-based account detection research. To address these issues, we propose a Multi-Relational Graph-Based Twitter Account Detection Benchmark (MGTAB), the first standardized graph-based benchmark for account detection. To our knowledge, MGTAB was built based on the largest original data in the field, with over 1.55 million users and 130 million tweets. MGTAB contains 10,199 expert-annotated users and 7 types of relationships, ensuring high-quality annotation and diversified relations. In MGTAB, we extracted the 20 user property features with the greatest information gain and user tweet features as the user features. In addition, we performed a thorough evaluation of MGTAB and other public datasets. Our experiments found that graph-based approaches are generally more effective than feature-based approaches and perform better when introducing multiple relations. By analyzing experiment results, we identify effective approaches for account detection and provide potential future research directions in this field. Our benchmark and standardized evaluation procedures are freely available at: https://github.com/GraphDetec/MGTAB.

Image Virtual try-on aims at replacing the cloth on a personal image with a garment image (in-shop clothes), which has attracted increasing attention from the multimedia and computer vision communities. Prior methods successfully preserve the character of clothing images, however, occlusion remains a pernicious effect for realistic virtual try-on. In this work, we first present a comprehensive analysis of the occlusions and categorize them into two aspects: i) Inherent-Occlusion: the ghost of the former cloth still exists in the try-on image; ii) Acquired-Occlusion: the target cloth warps to the unreasonable body part. Based on the in-depth analysis, we find that the occlusions can be simulated by a novel semantically-guided mixup module, which can generate semantic-specific occluded images that work together with the try-on images to facilitate training a de-occlusion try-on (DOC-VTON) framework. Specifically, DOC-VTON first conducts a sharpened semantic parsing on the try-on person. Aided by semantics guidance and pose prior, various complexities of texture are selectively blending with human parts in a copy-and-paste manner. Then, the Generative Module (GM) is utilized to take charge of synthesizing the final try-on image and learning to de-occlusion jointly. In comparison to the state-of-the-art methods, DOC-VTON achieves better perceptual quality by reducing occlusion effects.

Dynamic treatment regimes assign personalized treatments to patients sequentially over time based on their baseline information and time-varying covariates. In mobile health applications, these covariates are typically collected at different frequencies over a long time horizon. In this paper, we propose a deep spectral Q-learning algorithm, which integrates principal component analysis (PCA) with deep Q-learning to handle the mixed frequency data. In theory, we prove that the mean return under the estimated optimal policy converges to that under the optimal one and establish its rate of convergence. The usefulness of our proposal is further illustrated via simulations and an application to a diabetes dataset.

As natural language processing (NLP) for gender bias becomes a significant interdisciplinary topic, the prevalent data-driven techniques such as large-scale language models suffer from data inadequacy and biased corpus, especially for languages with insufficient resources such as Chinese. To this end, we propose a Chinese cOrpus foR Gender bIas Probing and Mitigation CORGI-PM, which contains 32.9k sentences with high-quality labels derived by following an annotation scheme specifically developed for gender bias in the Chinese context. Moreover, we address three challenges for automatic textual gender bias mitigation, which requires the models to detect, classify, and mitigate textual gender bias. We also conduct experiments with state-of-the-art language models to provide baselines. To our best knowledge, CORGI-PM is the first sentence-level Chinese corpus for gender bias probing and mitigation.

Off-policy evaluation (OPE) is a method for estimating the return of a target policy using some pre-collected observational data generated by a potentially different behavior policy. In some cases, there may be unmeasured variables that can confound the action-reward or action-next-state relationships, rendering many existing OPE approaches ineffective. This paper develops an instrumental variable (IV)-based method for consistent OPE in confounded Markov decision processes (MDPs). Similar to single-stage decision making, we show that IV enables us to correctly identify the target policy's value in infinite horizon settings as well. Furthermore, we propose an efficient and robust value estimator and illustrate its effectiveness through extensive simulations and analysis of real data from a world-leading short-video platform.
