Detecting abrupt changes in data distribution is one of the most significant tasks in streaming data analysis. Although many unsupervised Change-Point Detection (CPD) methods have been proposed recently to identify those changes, they still suffer from missing subtle changes, poor scalability, or/and sensitive to noise points. To meet these challenges, we are the first to generalise the CPD problem as a special case of the Change-Interval Detection (CID) problem. Then we propose a CID method, named iCID, based on a recent Isolation Distributional Kernel (IDK). iCID identifies the change interval if there is a high dissimilarity score between two non-homogeneous temporal adjacent intervals. The data-dependent property and finite feature map of IDK enabled iCID to efficiently identify various types of change points in data streams with the tolerance of noise points. Moreover, the proposed online and offline versions of iCID have the ability to optimise key parameter settings. The effectiveness and efficiency of iCID have been systematically verified on both synthetic and real-world datasets.

This paper investigates a phenomenon where query-based object detectors mispredict at the last decoding stage while predicting correctly at an intermediate stage. We review the training process and attribute the overlooked phenomenon to two limitations: lack of training emphasis and cascading errors from decoding sequence. We design and present Selective Query Recollection (SQR), a simple and effective training strategy for query-based object detectors. It cumulatively collects intermediate queries as decoding stages go deeper and selectively forwards the queries to the downstream stages aside from the sequential structure. Such-wise, SQR places training emphasis on later stages and allows later stages to work with intermediate queries from earlier stages directly. SQR can be easily plugged into various query-based object detectors and significantly enhances their performance while leaving the inference pipeline unchanged. As a result, we apply SQR on Adamixer, DAB-DETR, and Deformable-DETR across various settings (backbone, number of queries, schedule) and consistently brings 1.4-2.8 AP improvement.

Monocular depth estimation is a challenging problem on which deep neural networks have demonstrated great potential. However, depth maps predicted by existing deep models usually lack fine-grained details due to the convolution operations and the down-samplings in networks. We find that increasing input resolution is helpful to preserve more local details while the estimation at low resolution is more accurate globally. Therefore, we propose a novel depth map fusion module to combine the advantages of estimations with multi-resolution inputs. Instead of merging the low- and high-resolution estimations equally, we adopt the core idea of Poisson fusion, trying to implant the gradient domain of high-resolution depth into the low-resolution depth. While classic Poisson fusion requires a fusion mask as supervision, we propose a self-supervised framework based on guided image filtering. We demonstrate that this gradient-based composition performs much better at noisy immunity, compared with the state-of-the-art depth map fusion method. Our lightweight depth fusion is one-shot and runs in real-time, making our method 80X faster than a state-of-the-art depth fusion method. Quantitative evaluations demonstrate that the proposed method can be integrated into many fully convolutional monocular depth estimation backbones with a significant performance boost, leading to state-of-the-art results of detail enhancement on depth maps.

High-quality traffic flow generation is the core module in building simulators for autonomous driving. However, the majority of available simulators are incapable of replicating traffic patterns that accurately reflect the various features of real-world data while also simulating human-like reactive responses to the tested autopilot driving strategies. Taking one step forward to addressing such a problem, we propose Realistic Interactive TrAffic flow (RITA) as an integrated component of existing driving simulators to provide high-quality traffic flow for the evaluation and optimization of the tested driving strategies. RITA is developed with fidelity, diversity, and controllability in consideration, and consists of two core modules called RITABackend and RITAKit. RITABackend is built to support vehicle-wise control and provide traffic generation models from real-world datasets, while RITAKit is developed with easy-to-use interfaces for controllable traffic generation via RITABackend. We demonstrate RITA's capacity to create diversified and high-fidelity traffic simulations in several highly interactive highway scenarios. The experimental findings demonstrate that our produced RITA traffic flows meet all three design goals, hence enhancing the completeness of driving strategy evaluation. Moreover, we showcase the possibility for further improvement of baseline strategies through online fine-tuning with RITA traffic flows.

点对特征（PPF）广泛用于6D姿势估计。在本文中，我们提出了一种基于PPF框架的有效的6D姿势估计方法。我们介绍了一个目标良好的下采样策略，该策略更多地集中在边缘区域，以有效地提取复杂的几何形状。提出了一种姿势假设验证方法来通过计算边缘匹配度来解决对称歧义。我们对两个具有挑战性的数据集和一个现实世界中收集的数据集进行评估，这证明了我们方法对姿势估计几何复杂，遮挡，对称对象的优越性。我们通过将其应用于模拟穿刺来进一步验证我们的方法。

本文介绍了端到端以任务为导向的对话（TOD）的本体学预验证的语言模型（OPAL）。与Chit-Chat对话模型不同，面向任务的对话模型至少满足两个特定于任务的模块：对话状态跟踪器（DST）和响应生成器（RG）。对话状态由域插槽值三元组成，它们被认为是用户搜索与域相关数据库的约束。带有带注释的对话状态的大规模面向任务的对话数据通常是无法访问的。它可以防止针对任务对话的审慎语言模型的开发。我们提出了一种简单而有效的预处理方法来减轻此问题，该方法由两个预审进阶段组成。第一阶段是在大规模上下文文本数据上预处理，其中文本的结构化信息是由信息提取工具提取的。为了弥合训练方法和下游任务之间的差距，我们设计了两个预训练的任务：类似于本体的三重恢复和下一文本生成，分别模拟了DST和RG。第二阶段是在TOD数据上微调验证的模型。实验结果表明，即使没有CAMREST676和MULTIWOZ基准的任何TOD数据，我们提出的方法即使没有任何TOD数据，我们提出的方法也可以提高竞争性能。

近年来，在自学学习（SSL）方面取得了重大成功，这有助于各种下游任务。但是，攻击者可能会窃取此类SSL模型并将其商业化以获利，这对于保护其知识产权（IP）至关重要。大多数现有的IP保护解决方案都是为监督学习模型而设计的，不能直接使用，因为它们要求模型的下游任务和目标标签在水印嵌入过程中已知并获得，这在SSL的域中并非总是可以的。为了解决此类问题，尤其是在水印嵌入过程中下游任务多样化且未知时，我们提出了一种新型的黑盒水印解决方案，名为SSL-WM，以保护SSL模型的所有权。 SSL-WM将水印编码器的水印输入映射到不变的表示空间中，该空间会导致任何下游分类器产生预期的行为，从而允许检测到嵌入式水印。我们使用不同的SSL模型（包括基于对比度和基于生成的生成型）来评估许多任务，例如计算机视觉（CV）和自然语言处理（NLP）等许多任务。实验结果表明，SSL-WM可以有效地验证各种下游任务中被盗SSL模型的所有权。此外，SSL-WM对模型进行微调和修剪攻击非常强大。最后，SSL-WM还可以从评估的水印检测方法中逃避检测，从而证明了其在保护SSL模型IP时的有希望的应用。

社会机器人的快速发展刺激了人类运动建模，解释和预测，主动碰撞，人类机器人相互作用和共享空间中共同损害的积极研究。现代方法的目标需要高质量的数据集进行培训和评估。但是，大多数可用数据集都遭受了不准确的跟踪数据或跟踪人员的不自然的脚本行为。本文试图通过在语义丰富的环境中提供运动捕获，眼睛凝视跟踪器和板载机器人传感器的高质量跟踪信息来填补这一空白。为了诱导记录参与者的自然行为，我们利用了松散的脚本化任务分配，这使参与者以自然而有目的的方式导航到动态的实验室环境。本文介绍的运动数据集设置了高质量的标准，因为使用语义信息可以增强现实和准确的数据，从而使新算法的开发不仅依赖于跟踪信息，而且还依赖于移动代理的上下文提示，还依赖于跟踪信息。静态和动态环境。

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。

在生成对抗网络（GAN）中操纵潜在代码的面部图像合成主要集中于连续属性合成（例如，年龄，姿势和情感），而离散属性合成（例如面膜和眼镜）受到较少的注意。直接将现有作品应用于面部离散属性可能会导致结果不正确。在这项工作中，我们提出了一个创新的框架，以通过语义分解，称为SD-GAN来解决具有挑战性的面部离散属性合成。要具体，我们将离散属性表示形式明确分解为两个组件，即语义先验和偏移潜在表示。语义先验基础显示了在潜在空间中操纵面部表示的初始化方向。提出了通过3D感知语义融合网络获得的偏移潜在呈现，以调整先前的基础。此外，融合网络集成了3D嵌入，以更好地身份保存和离散属性合成。先前基础和抵消潜在表示的组合使我们的方法能够合成具有离散属性的照片真实面部图像。值得注意的是，我们构建了一个大型且有价值的数据集MEGN（从Google和Naver捕获的面膜和眼镜图像），以完成现有数据集中缺乏离散属性。广泛的定性和定量实验证明了我们方法的最新性能。我们的代码可在以下网址找到：https：//github.com/montaellis/sd-gan。
