There are many artificial intelligence algorithms for autonomous driving, but directly installing these algorithms on vehicles is unrealistic and expensive. At the same time, many of these algorithms need an environment to train and optimize. Simulation is a valuable and meaningful solution with training and testing functions, and it can say that simulation is a critical link in the autonomous driving world. There are also many different applications or systems of simulation from companies or academies such as SVL and Carla. These simulators flaunt that they have the closest real-world simulation, but their environment objects, such as pedestrians and other vehicles around the agent-vehicle, are already fixed programmed. They can only move along the pre-setting trajectory, or random numbers determine their movements. What is the situation when all environmental objects are also installed by Artificial Intelligence, or their behaviors are like real people or natural reactions of other drivers? This problem is a blind spot for most of the simulation applications, or these applications cannot be easy to solve this problem. The Neurorobotics Platform from the TUM team of Prof. Alois Knoll has the idea about "Engines" and "Transceiver Functions" to solve the multi-agents problem. This report will start with a little research on the Neurorobotics Platform and analyze the potential and possibility of developing a new simulator to achieve the true real-world simulation goal. Then based on the NRP-Core Platform, this initial development aims to construct an initial demo experiment. The consist of this report starts with the basic knowledge of NRP-Core and its installation, then focus on the explanation of the necessary components for a simulation experiment, at last, about the details of constructions for the autonomous driving system, which is integrated object detection and autonomous control.

A computational graph in a deep neural network (DNN) denotes a specific data flow diagram (DFD) composed of many tensors and operators. Existing toolkits for visualizing computational graphs are not applicable when the structure is highly complicated and large-scale (e.g., BERT [1]). To address this problem, we propose leveraging a suite of visual simplification techniques, including a cycle-removing method, a module-based edge-pruning algorithm, and an isomorphic subgraph stacking strategy. We design and implement an interactive visualization system that is suitable for computational graphs with up to 10 thousand elements. Experimental results and usage scenarios demonstrate that our tool reduces 60% elements on average and hence enhances the performance for recognizing and diagnosing DNN models. Our contributions are integrated into an open-source DNN visualization toolkit, namely, MindInsight [2].

Most research on task oriented dialog modeling is based on written text input. However, users interact with practical dialog systems often using speech as input. Typically, systems convert speech into text using an Automatic Speech Recognition (ASR) system, introducing errors. Furthermore, these systems do not address the differences in written and spoken language. The research on this topic is stymied by the lack of a public corpus. Motivated by these considerations, our goal in hosting the speech-aware dialog state tracking challenge was to create a public corpus or task which can be used to investigate the performance gap between the written and spoken forms of input, develop models that could alleviate this gap, and establish whether Text-to-Speech-based (TTS) systems is a reasonable surrogate to the more-labor intensive human data collection. We created three spoken versions of the popular written-domain MultiWoz task -- (a) TTS-Verbatim: written user inputs were converted into speech waveforms using a TTS system, (b) Human-Verbatim: humans spoke the user inputs verbatim, and (c) Human-paraphrased: humans paraphrased the user inputs. Additionally, we provided different forms of ASR output to encourage wider participation from teams that may not have access to state-of-the-art ASR systems. These included ASR transcripts, word time stamps, and latent representations of the audio (audio encoder outputs). In this paper, we describe the corpus, report results from participating teams, provide preliminary analyses of their results, and summarize the current state-of-the-art in this domain.

Whole-slide images (WSI) in computational pathology have high resolution with gigapixel size, but are generally with sparse regions of interest, which leads to weak diagnostic relevance and data inefficiency for each area in the slide. Most of the existing methods rely on a multiple instance learning framework that requires densely sampling local patches at high magnification. The limitation is evident in the application stage as the heavy computation for extracting patch-level features is inevitable. In this paper, we develop RLogist, a benchmarking deep reinforcement learning (DRL) method for fast observation strategy on WSIs. Imitating the diagnostic logic of human pathologists, our RL agent learns how to find regions of observation value and obtain representative features across multiple resolution levels, without having to analyze each part of the WSI at the high magnification. We benchmark our method on two whole-slide level classification tasks, including detection of metastases in WSIs of lymph node sections, and subtyping of lung cancer. Experimental results demonstrate that RLogist achieves competitive classification performance compared to typical multiple instance learning algorithms, while having a significantly short observation path. In addition, the observation path given by RLogist provides good decision-making interpretability, and its ability of reading path navigation can potentially be used by pathologists for educational/assistive purposes.

Face Restoration (FR) aims to restore High-Quality (HQ) faces from Low-Quality (LQ) input images, which is a domain-specific image restoration problem in the low-level computer vision area. The early face restoration methods mainly use statistic priors and degradation models, which are difficult to meet the requirements of real-world applications in practice. In recent years, face restoration has witnessed great progress after stepping into the deep learning era. However, there are few works to study deep learning-based face restoration methods systematically. Thus, this paper comprehensively surveys recent advances in deep learning techniques for face restoration. Specifically, we first summarize different problem formulations and analyze the characteristic of the face image. Second, we discuss the challenges of face restoration. Concerning these challenges, we present a comprehensive review of existing FR methods, including prior based methods and deep learning-based methods. Then, we explore developed techniques in the task of FR covering network architectures, loss functions, and benchmark datasets. We also conduct a systematic benchmark evaluation on representative methods. Finally, we discuss future directions, including network designs, metrics, benchmark datasets, applications,etc. We also provide an open-source repository for all the discussed methods, which is available at https://github.com/TaoWangzj/Awesome-Face-Restoration.

激光镜头和相机是两个用于自动驾驶中3D感知的互补传感器。激光点云具有准确的空间和几何信息，而RGB图像为上下文推理提供了纹理和颜色数据。为了共同利用激光雷达和相机，现有的融合方法倾向于基于校准，即一对一的映射，将每个3D点与一个投影图像像素对齐。但是，这些方法的性能高度依赖于校准质量，这对传感器的时间和空间同步敏感。因此，我们提出了一个动态的交叉注意（DCA）模块，具有新型的一对一的交叉模式映射，该模块从初始投影对邻域的最初投影中学习了多个偏移，从而发展了对校准误差的耐受性。此外，提出了A \ textIt {动态查询增强}来感知与模型无关的校准，从而进一步增强了DCA对初始未对准的耐受性。名为“动态跨注意网络”（DCAN）的整个融合体系结构利用了多级图像特征，并适应了点云的多个表示，这使DCA可以用作插件融合模块。对Nuscenes和Kitti的广泛实验证明了DCA的有效性。拟议的DCAN在Nuscenes检测挑战上优于最先进的方法。

这项工作提出了下一代人类机器人界面，只能通过视觉来推断和实现用户的操纵意图。具体而言，我们开发了一个集成了近眼跟踪和机器人操作的系统，以实现用户指定的操作（例如，抓取，拾取和位置等），在其中将视觉信息与人类的注意合并在一起，以创建为所需的映射机器人动作。为了实现视力指导的操纵，开发了一个头部安装的近眼跟踪设备，以实时跟踪眼球运动，以便可以确定用户的视觉注意力。为了提高抓地力性能，然后开发出基于变压器的GRASP模型。堆叠的变压器块用于提取层次特征，其中在每个阶段扩展了通道的体积，同时挤压了特征地图的分辨率。实验验证表明，眼球跟踪系统产生低的凝视估计误差，抓地力系统在多个握把数据集上产生有希望的结果。这项工作是基于凝视互动的辅助机器人的概念证明，该机器人具有巨大的希望，可以帮助老年人或上肢残疾在日常生活中。可在\ url {https://www.youtube.com/watch?v=yuz1hukyurm}上获得演示视频。

热应力和变形的快速分析在热控制措施和卫星结构设计的优化中起着关键作用。为了实现卫星主板的实时热应力和热变形分析，本文提出了一种新型的多任务注意UNET（MTA-UNET）神经网络，将多任务学习（MTL）和U-NET的优势结合在一起注意机制。此外，在训练过程中使用了物理知识的策略，其中部分微分方程（PDE）被整合到损失函数中作为残留项。最后，将基于不确定性的损失平衡方法应用于重量的多个培训任务的不同损失功能。实验结果表明，与单任务学习（STL）模型相比，提出的MTA-UNET有效提高了多个物理任务的预测准确性。此外，物理信息的方法在每个任务的预测中的错误较小，尤其是在小型数据集上。代码可以在：\ url {https://github.com/komorebitso/mta-unet}下载。

在线行动检测旨在基于长期的历史观察结果对当前框架进行准确的行动预测。同时，它需要对在线流视频进行实时推断。在本文中，我们主张一个新颖有效的在线行动检测原则。它仅在一个窗口中更新最新，最古老的历史表示，但重复了已经计算的中间图表。基于这一原则，我们引入了一个基于窗口的级联变压器，带有圆形历史队列，在每个窗口上都进行了多阶段的注意力和级联精炼。我们还探讨了在线操作检测与其脱机行动分段作为辅助任务之间的关联。我们发现，这种额外的监督有助于判别历史的聚类，并充当功能增强，以更好地培训分类器和级联改善。我们提出的方法在三个具有挑战性的数据集Thumos'14，TVSeries和HDD上实现了最新的表演。接受后将可用。

AD相关建模在包括Microsoft Bing在内的在线广告系统中起着至关重要的作用。为了利用强大的变压器在这种低延迟设置中，许多现有方法脱机执行广告端计算。虽然有效，但这些方法无法提供冷启动广告，从而导致对此类广告的相关性预测不佳。这项工作旨在通过结构化修剪设计一种新的低延迟BERT，以在CPU平台上授权实时在线推断对Cold Start Ads相关性。我们的挑战是，以前的方法通常将变压器的所有层都缩减为高，均匀的稀疏性，从而产生无法以可接受的精度实现令人满意的推理速度的模型。在本文中，我们提出了SwiftPruner - 一个有效的框架，利用基于进化的搜索自动在所需的延迟约束下自动找到表现最佳的稀疏BERT模型。与进行随机突变的现有进化算法不同，我们提出了一个具有潜伏意见的多目标奖励的增强突变器，以进行更好的突变，以有效地搜索层稀疏模型的大空间。广泛的实验表明，与均匀的稀疏基线和最先进的搜索方法相比，我们的方法始终达到更高的ROC AUC和更低的潜伏度。值得注意的是，根据我们在1900年的延迟需求，SwiftPruner的AUC比Bert-Mini在大型现实世界数据集中的最先进的稀疏基线高0.86％。在线A/B测试表明，我们的模型还达到了有缺陷的冷启动广告的比例，并获得了令人满意的实时服务延迟。
