Causal chain reasoning (CCR) is an essential ability for many decision-making AI systems, which requires the model to build reliable causal chains by connecting causal pairs. However, CCR suffers from two main transitive problems: threshold effect and scene drift. In other words, the causal pairs to be spliced may have a conflicting threshold boundary or scenario. To address these issues, we propose a novel Reliable Causal chain reasoning framework~(ReCo), which introduces exogenous variables to represent the threshold and scene factors of each causal pair within the causal chain, and estimates the threshold and scene contradictions across exogenous variables via structural causal recurrent neural networks~(SRNN). Experiments show that ReCo outperforms a series of strong baselines on both Chinese and English CCR datasets. Moreover, by injecting reliable causal chain knowledge distilled by ReCo, BERT can achieve better performances on four downstream causal-related tasks than BERT models enhanced by other kinds of knowledge.

We propose a sparse end-to-end multi-person pose regression framework, termed QueryPose, which can directly predict multi-person keypoint sequences from the input image. The existing end-to-end methods rely on dense representations to preserve the spatial detail and structure for precise keypoint localization. However, the dense paradigm introduces complex and redundant post-processes during inference. In our framework, each human instance is encoded by several learnable spatial-aware part-level queries associated with an instance-level query. First, we propose the Spatial Part Embedding Generation Module (SPEGM) that considers the local spatial attention mechanism to generate several spatial-sensitive part embeddings, which contain spatial details and structural information for enhancing the part-level queries. Second, we introduce the Selective Iteration Module (SIM) to adaptively update the sparse part-level queries via the generated spatial-sensitive part embeddings stage-by-stage. Based on the two proposed modules, the part-level queries are able to fully encode the spatial details and structural information for precise keypoint regression. With the bipartite matching, QueryPose avoids the hand-designed post-processes and surpasses the existing dense end-to-end methods with 73.6 AP on MS COCO mini-val set and 72.7 AP on CrowdPose test set. Code is available at https://github.com/buptxyb666/QueryPose.

Social media has been one of the main information consumption sources for the public, allowing people to seek and spread information more quickly and easily. However, the rise of various social media platforms also enables the proliferation of online misinformation. In particular, misinformation in the health domain has significant impacts on our society such as the COVID-19 infodemic. Therefore, health misinformation in social media has become an emerging research direction that attracts increasing attention from researchers of different disciplines. Compared to misinformation in other domains, the key differences of health misinformation include the potential of causing actual harm to humans' bodies and even lives, the hardness to identify for normal people, and the deep connection with medical science. In addition, health misinformation on social media has distinct characteristics from conventional channels such as television on multiple dimensions including the generation, dissemination, and consumption paradigms. Because of the uniqueness and importance of combating health misinformation in social media, we conduct this survey to further facilitate interdisciplinary research on this problem. In this survey, we present a comprehensive review of existing research about online health misinformation in different disciplines. Furthermore, we also systematically organize the related literature from three perspectives: characterization, detection, and intervention. Lastly, we conduct a deep discussion on the pressing open issues of combating health misinformation in social media and provide future directions for multidisciplinary researchers.

知识图（kg）嵌入是一种主流方法，用于推理不完整的kg。但是，受其固有浅层和静态体系结构的限制，它们几乎无法处理对复杂逻辑查询的不断上升，这些查询包括逻辑运算符，估算的边缘，多个源实体和未知的中间实体。在这项工作中，我们通过掩盖的预训练和微调策略介绍了知识图变压器（kgtransformer）。我们设计了一种kg三重变换方法，以使变压器能够处理kg，这是通过稀疏（MOE）稀疏激活的混合物进一步增强的。然后，我们将复杂的逻辑查询作为掩盖预测提出，并引入了两阶段掩盖的预训练策略，以提高可转移性和概括性。在两个基准上进行的广泛实验表明，KGTRANSFORMER可以始终超过基于KG的基准和九个内域和室外推理任务的高级编码。此外，KGTRANSFORMER可以通过提供解释给定答案的完整推理路径来解释性。

变压器的扎实结果使它们在各种自然语言和视觉任务中占上风。作为变压器中的默认组件，层归一化（LN）将每个令牌内的激活归一化，以增强稳健性。但是，LN需要在推理以及除法和平方根操作中进行直接统计计算，从而导致硬件效率低下。更重要的是，用其他硬件有效的标准化方案（例如，批发归一化）代替LN会导致性能较低，甚至在训练中崩溃。我们发现，这种困境是由激活统计的异常行为引起的，包括对迭代的大波动和跨层的极端异常值。为了解决这些问题，我们提出了统一的归一化（UN），可以通过与其他线性操作融合并在LN上实现可比性的性能来加快推断。联合国通过量身定制的波动平滑策略校准激活和梯度统计来努力提高性能。同时，采用自适应离群过滤策略来避免在本文中在理论上证明并在实验上验证的训练中崩溃。我们证明，通过对语言和视觉任务进行广泛的实验，联合国可以成为LN的有效替代品。此外，我们评估了我们方法在GPU上的效率。配备了联合国的变压器享受约31％的推理速度和近18％的记忆力减少。代码将在https://github.com/hikvision-research/unified-normalization上发布。

可靠的导航系统在机器人技术和自动驾驶中具有广泛的应用。当前方法采用开环过程，将传感器输入直接转换为动作。但是，这些开环方案由于概括不佳而在处理复杂而动态的现实情况方面具有挑战性。在模仿人类导航的情况下，我们添加了一个推理过程，将动作转换回内部潜在状态，形成了两阶段的感知，决策和推理的封闭环路。首先，VAE增强的演示学习赋予了模型对基本导航规则的理解。然后，在RL增强交互学习中的两个双重过程彼此产生奖励反馈，并共同增强了避免障碍能力。推理模型可以实质上促进概括和鲁棒性，并促进算法将算法的部署到现实世界的机器人，而无需精心转移。实验表明，与最先进的方法相比，我们的方法更适合新型方案。

我们介绍了深度学习时代的首次全面视频息肉细分（VPS）研究。多年来，由于缺乏大规模细粒度分割注释，VPS的发展并没有轻松前进。为了解决此问题，我们首先引入了名为Sun-Seg的高质量逐帧注释数据集，其中包含来自著名的Sun-Database的158,690帧。我们提供具有不同类型的其他注释，即属性，对象掩码，边界，涂鸦和多边形。其次，我们设计了一个简单但有效的基线，称为PNS+，由全局编码器，局部编码器和归一化的自我注意（NS）块组成。全球和本地编码器会收到一个锚固框架和多个连续的帧，以提取长期和短期时空表示，然后由两个NS块逐渐更新。广泛的实验表明，PNS+实现了最佳性能和实时推理速度（170FPS），这使其成为VPS任务的有前途解决方案。第三，我们在Sun-Seg数据集中广泛评估13个代表性息肉/对象分割模型，并提供基于属性的比较。最后，我们讨论了几个开放问题，并为VPS社区提出了可能的研究指示。

我们识别普遍对抗扰动（UAP）的性质，将它们与标准的对抗性扰动区分开来。具体而言，我们表明，由投影梯度下降产生的靶向UAPS表现出两种人对齐的特性：语义局部性和空间不变性，标准的靶向对抗扰动缺乏。我们还证明，除标准对抗扰动之外，UAPS含有明显较低的泛化信号 - 即，UAPS在比标准的对抗的扰动的较小程度上利用非鲁棒特征。

自动驾驶技术的加速开发对获得大量高质量数据的需求更大。标签，现实世界数据代表性是培训深度学习网络的燃料，对于改善自动驾驶感知算法至关重要。在本文中，我们介绍了PANDASET，由完整的高精度自动车辆传感器套件生产的第一个数据集，具有无需成本商业许可证。使用一个360 {\ DEG}机械纺丝利达，一个前置，远程LIDAR和6个摄像机收集数据集。DataSet包含100多个场景，每个场景为8秒，为目标分类提供28种类型的标签和37种类型的语义分割标签。我们提供仅限LIDAR 3D对象检测的基线，LIDAR-Camera Fusion 3D对象检测和LIDAR点云分割。有关Pandaset和开发套件的更多详细信息，请参阅https://scale.com/open-datasets/pandaset。

尽管数十年的努力，但在真正的情景中的机器人导航具有波动性，不确定性，复杂性和歧义（vuca短暂），仍然是一个具有挑战性的话题。受到中枢神经系统（CNS）的启发，我们提出了一个在Vuca环境中的自主导航的分层多专家学习框架。通过考虑目标位置，路径成本和安全水平的启发式探索机制，上层执行同时映射探索和路线规划，以避免陷入盲巷，类似于CNS中的大脑。使用本地自适应模型融合多种差异策略，下层追求碰撞 - 避免和直接策略之间的平衡，作为CNS中的小脑。我们在多个平台上进行仿真和实际实验，包括腿部和轮式机器人。实验结果表明我们的算法在任务成就，时间效率和安全性方面优于现有方法。
