驾驶员注意力预测的任务引起了研究人员对机器人技术和自动驾驶汽车行业的极大兴趣。驾驶员注意力预测可以在缓解和预防高风险事件（如碰撞和伤亡）中发挥工具作用。但是，现有的驾驶员注意力预测模型忽略了驾驶员的分心状态和意图，这可能会极大地影响他们观察周围环境的方式。为了解决这些问题，我们提出了一个新的驾驶员注意数据集Cocatt（认知条件的注意力）。与以前的驾驶员注意数据集不同，Cocatt包括描述驾驶员的分心状态和意图的人均注释。此外，我们的数据集中的注意力数据使用不同分辨率的眼睛跟踪设备在手动和自动驾驶模式中捕获。我们的结果表明，将上述两个驱动程序状态纳入注意力建模可以提高驾驶员注意力预测的性能。据我们所知，这项工作是第一个提供自动驾驶注意数据的工作。此外，就自主性水平，眼动分辨率和驾驶场景而言，Cocatt目前是最大，最多样化的驾驶员注意数据集。 Cocatt可在https://cocatt-dataset.github.io上下载。

This paper presents a state-of-the-art optimal controller for quadruped locomotion. The robot dynamics is represented using a single rigid body (SRB) model. A linear time-varying model predictive controller (LTV MPC) is proposed by using linearization schemes. Simulation results show that the LTV MPC can execute various gaits, such as trot and crawl, and is capable of tracking desired reference trajectories even under unknown external disturbances. The LTV MPC is implemented as a quadratic program using qpOASES through the CasADi interface at 50 Hz. The proposed MPC can reach up to 1 m/s top speed with an acceleration of 0.5 m/s2 executing a trot gait. The implementation is available at https:// github.com/AndrewZheng-1011/Quad_ConvexMPC

Graph neural networks (GNNs) have recently emerged as a promising learning paradigm in learning graph-structured data and have demonstrated wide success across various domains such as recommendation systems, social networks, and electronic design automation (EDA). Like other deep learning (DL) methods, GNNs are being deployed in sophisticated modern hardware systems, as well as dedicated accelerators. However, despite the popularity of GNNs and the recent efforts of bringing GNNs to hardware, the fault tolerance and resilience of GNNs has generally been overlooked. Inspired by the inherent algorithmic resilience of DL methods, this paper conducts, for the first time, a large-scale and empirical study of GNN resilience, aiming to understand the relationship between hardware faults and GNN accuracy. By developing a customized fault injection tool on top of PyTorch, we perform extensive fault injection experiments to various GNN models and application datasets. We observe that the error resilience of GNN models varies by orders of magnitude with respect to different models and application datasets. Further, we explore a low-cost error mitigation mechanism for GNN to enhance its resilience. This GNN resilience study aims to open up new directions and opportunities for future GNN accelerator design and architectural optimization.

Chest X-ray (CXR) datasets hosted on Kaggle, though useful from a data science competition standpoint, have limited utility in clinical use because of their narrow focus on diagnosing one specific disease. In real-world clinical use, multiple diseases need to be considered since they can co-exist in the same patient. In this work, we demonstrate how federated learning (FL) can be used to make these toy CXR datasets from Kaggle clinically useful. Specifically, we train a single FL classification model (`global`) using two separate CXR datasets -- one annotated for presence of pneumonia and the other for presence of pneumothorax (two common and life-threatening conditions) -- capable of diagnosing both. We compare the performance of the global FL model with models trained separately on both datasets (`baseline`) for two different model architectures. On a standard, naive 3-layer CNN architecture, the global FL model achieved AUROC of 0.84 and 0.81 for pneumonia and pneumothorax, respectively, compared to 0.85 and 0.82, respectively, for both baseline models (p>0.05). Similarly, on a pretrained DenseNet121 architecture, the global FL model achieved AUROC of 0.88 and 0.91 for pneumonia and pneumothorax, respectively, compared to 0.89 and 0.91, respectively, for both baseline models (p>0.05). Our results suggest that FL can be used to create global `meta` models to make toy datasets from Kaggle clinically useful, a step forward towards bridging the gap from bench to bedside.

We present pyRDDLGym, a Python framework for auto-generation of OpenAI Gym environments from RDDL declerative description. The discrete time step evolution of variables in RDDL is described by conditional probability functions, which fits naturally into the Gym step scheme. Furthermore, since RDDL is a lifted description, the modification and scaling up of environments to support multiple entities and different configurations becomes trivial rather than a tedious process prone to errors. We hope that pyRDDLGym will serve as a new wind in the reinforcement learning community by enabling easy and rapid development of benchmarks due to the unique expressive power of RDDL. By providing explicit access to the model in the RDDL description, pyRDDLGym can also facilitate research on hybrid approaches for learning from interaction while leveraging model knowledge. We present the design and built-in examples of pyRDDLGym, and the additions made to the RDDL language that were incorporated into the framework.

We discuss a platform that has both software and hardware components, and whose purpose is to support research into characterizing and mitigating the sim-to-real gap in robotics and vehicle autonomy engineering. The software is operating-system independent and has three main components: a simulation engine called Chrono, which supports high-fidelity vehicle and sensor simulation; an autonomy stack for algorithm design and testing; and a development environment that supports visualization and hardware-in-the-loop experimentation. The accompanying hardware platform is a 1/6th scale vehicle augmented with reconfigurable mountings for computing, sensing, and tracking. Since this vehicle platform has a digital twin within the simulation environment, one can test the same autonomy perception, state estimation, or controls algorithms, as well as the processors they run on, in both simulation and reality. A demonstration is provided to show the utilization of this platform for autonomy research. Future work will concentrate on augmenting ART/ATK with support for a full-sized Chevy Bolt EUV, which will be made available to this group in the immediate future.

在具有可再生生成的大量份额的网格中，由于负载和发电的波动性增加，运营商将需要其他工具来评估运营风险。正向不确定性传播问题的计算要求必须解决众多安全受限的经济调度（SCED）优化，是这种实时风险评估的主要障碍。本文提出了一个即时风险评估学习框架（Jitralf）作为替代方案。 Jitralf训练风险代理，每天每小时一个，使用机器学习（ML）来预测估计风险所需的数量，而无需明确解决SCED问题。这大大减轻了正向不确定性传播的计算负担，并允许快速，实时的风险估计。本文还提出了一种新颖的，不对称的损失函数，并表明使用不对称损失训练的模型的性能优于使用对称损耗函数的模型。在法国传输系统上评估了Jitralf，以评估运营储量不足的风险，减轻负载的风险和预期的运营成本。

与标准动态范围（SDR）视频相比，高动态范围（HDR）视频可以代表更大的亮度和色彩范围，并且正迅速成为行业标准。与传统SDR视频相比，HDR视频具有更具挑战性的捕获，传输和显示要求。凭借其更大的深度，高级的电流传输功能以及更广泛的颜色范围，因此需要专门设计用于预测HDR视频质量的视频质量算法。为此，我们介绍了HDR视频的首次公开发布的大规模主观研究。我们研究扭曲的影响，例如压缩和混叠对HDR视频质量的影响。我们还通过在黑暗实验室环境和更明亮的客厅环境中进行研究来研究环境照明对HDR视频感知质量的影响。总共有66名受试者参加了这项研究，并收集了20,000多个意见分数，这使得这成为有史以来最大的HDR视频质量研究。我们预计，该数据集将成为研究人员为HDR视频开发更好的感知质量模型的宝贵资源。
