In a typical car-following scenario, target vehicle speed fluctuations act as an external disturbance to the host vehicle and in turn affect its energy consumption. To control a host vehicle in an energy-efficient manner using model predictive control (MPC), and moreover, enhance the performance of an ecological adaptive cruise control (EACC) strategy, forecasting the future velocities of a target vehicle is essential. For this purpose, a deep recurrent neural network-based vehicle speed prediction using long-short term memory (LSTM) and gated recurrent units (GRU) is studied in this work. Besides these, the physics-based constant velocity (CV) and constant acceleration (CA) models are discussed. The sequential time series data for training (e.g. speed trajectories of the target and its preceding vehicles obtained through vehicle-to-vehicle (V2V) communication, road speed limits, traffic light current and future phases collected using vehicle-to-infrastructure (V2I) communication) is gathered from both urban and highway networks created in the microscopic traffic simulator SUMO. The proposed speed prediction models are evaluated for long-term predictions (up to 10 s) of target vehicle future velocities. Moreover, the results revealed that the LSTM-based speed predictor outperformed other models in terms of achieving better prediction accuracy on unseen test datasets, and thereby showcasing better generalization ability. Furthermore, the performance of EACC-equipped host car on the predicted velocities is evaluated, and its energy-saving benefits for different prediction horizons are presented.

Knowledge about space and time is necessary to solve problems in the physical world: An AI agent situated in the physical world and interacting with objects often needs to reason about positions of and relations between objects; and as soon as the agent plans its actions to solve a task, it needs to consider the temporal aspect (e.g., what actions to perform over time). Spatio-temporal knowledge, however, is required beyond interacting with the physical world, and is also often transferred to the abstract world of concepts through analogies and metaphors (e.g., "a threat that is hanging over our heads"). As spatial and temporal reasoning is ubiquitous, different attempts have been made to integrate this into AI systems. In the area of knowledge representation, spatial and temporal reasoning has been largely limited to modeling objects and relations and developing reasoning methods to verify statements about objects and relations. On the other hand, neural network researchers have tried to teach models to learn spatial relations from data with limited reasoning capabilities. Bridging the gap between these two approaches in a mutually beneficial way could allow us to tackle many complex real-world problems, such as natural language processing, visual question answering, and semantic image segmentation. In this chapter, we view this integration problem from the perspective of Neuro-Symbolic AI. Specifically, we propose a synergy between logical reasoning and machine learning that will be grounded on spatial and temporal knowledge. Describing some successful applications, remaining challenges, and evaluation datasets pertaining to this direction is the main topic of this contribution.

This paper presents an accurate, highly efficient, and learning-free method for large-scale odometry estimation using spinning radar, empirically found to generalize well across very diverse environments -- outdoors, from urban to woodland, and indoors in warehouses and mines - without changing parameters. Our method integrates motion compensation within a sweep with one-to-many scan registration that minimizes distances between nearby oriented surface points and mitigates outliers with a robust loss function. Extending our previous approach CFEAR, we present an in-depth investigation on a wider range of data sets, quantifying the importance of filtering, resolution, registration cost and loss functions, keyframe history, and motion compensation. We present a new solving strategy and configuration that overcomes previous issues with sparsity and bias, and improves our state-of-the-art by 38%, thus, surprisingly, outperforming radar SLAM and approaching lidar SLAM. The most accurate configuration achieves 1.09% error at 5Hz on the Oxford benchmark, and the fastest achieves 1.79% error at 160Hz.

ICECUBE是一种用于检测1 GEV和1 PEV之间大气和天体中微子的光学传感器的立方公斤阵列，该阵列已部署1.45 km至2.45 km的南极的冰盖表面以下1.45 km至2.45 km。来自ICE探测器的事件的分类和重建在ICeCube数据分析中起着核心作用。重建和分类事件是一个挑战，这是由于探测器的几何形状，不均匀的散射和冰中光的吸收，并且低于100 GEV的光，每个事件产生的信号光子数量相对较少。为了应对这一挑战，可以将ICECUBE事件表示为点云图形，并将图形神经网络（GNN）作为分类和重建方法。 GNN能够将中微子事件与宇宙射线背景区分开，对不同的中微子事件类型进行分类，并重建沉积的能量，方向和相互作用顶点。基于仿真，我们提供了1-100 GEV能量范围的比较与当前ICECUBE分析中使用的当前最新最大似然技术，包括已知系统不确定性的影响。对于中微子事件分类，与当前的IceCube方法相比，GNN以固定的假阳性速率（FPR）提高了信号效率的18％。另外，GNN在固定信号效率下将FPR的降低超过8（低于半百分比）。对于能源，方向和相互作用顶点的重建，与当前最大似然技术相比，分辨率平均提高了13％-20％。当在GPU上运行时，GNN能够以几乎是2.7 kHz的中位数ICECUBE触发速率的速率处理ICECUBE事件，这打开了在在线搜索瞬态事件中使用低能量中微子的可能性。

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。

在这项工作中，我们提出了一种神经方法，用于重建描述层次相互作用的生根树图，使用新颖的表示，我们将其称为最低的共同祖先世代（LCAG）矩阵。这种紧凑的配方等效于邻接矩阵，但是如果直接使用邻接矩阵，则可以单独从叶子中学习树的结构，而无需先前的假设。因此，采用LCAG启用了第一个端到端的可训练解决方案，该解决方案仅使用末端树叶直接学习不同树大小的层次结构。在高能量粒子物理学的情况下，粒子衰减形成了分层树结构，只能通过实验观察到最终产物，并且可能的树的大型组合空间使分析溶液变得很棘手。我们证明了LCAG用作使用变压器编码器和神经关系编码器编码器图神经网络的模拟粒子物理衰减结构的任务。采用这种方法，我们能够正确预测LCAG纯粹是从叶子特征中的LCAG，最大树深度为$ 8 $ in $ 92.5 \％\％的树木箱子，最高$ 6 $叶子（包括）和$ 59.7 \％\％\％\％的树木$在我们的模拟数据集中$ 10 $。

机器人越来越多地部署在与人类共享的空间中，包括家庭环境和工业环境。在这些环境中，人与机器人之间的相互作用（HRI）对于安全性，可读性和效率至关重要。 HRI的一个关键因素是信任，它调节了系统的接受。已显示拟人化可以调节机器人的信任发展，但工业环境中的机器人通常不是拟人化的。我们在工业环境中设计了一个简单的互动，在该环境中，拟人化模拟驱动器（ARMOD）机器人模拟了自动驾驶汽车（AGV）。该任务由与AGV的人类交叉路径组成，有或不带有狭窄的走廊上安装在顶部。人类和系统在越过路径时需要协商轨迹，这意味着人必须关注机器人的轨迹，以避免与它发生碰撞。在存在ARMOD的情况下，报告的信任评分有显着的增长，表明拟人化机器人的存在足以调节信任，即使在有限的相互作用中，就像我们在这里提出的相互作用一样。

手动检查粪便涂片样品以鉴定寄生卵的存在非常耗时，只能由专家进行。因此，需要自动化系统来解决此问题，因为它可以与严重的肠道寄生虫感染有关。本文回顾了微观图像中关于寄生卵检测和分类的ICIP 2022挑战。我们描述了此应用程序的新数据集，该数据集是同类数据集的最大数据集。参与者在挑战中使用的方法及其结果及其结果进行了汇总和讨论。

近年来，人类运动轨迹预测是许多领域自治系统的重要任务。通过不同社区提出的多种新方法，缺乏标准化的基准和客观比较越来越成为评估进度并指导进一步研究的主要局限性。现有基准的范围和灵活性有限，无法进行相关实验，并说明了代理和环境的上下文提示。在本文中，我们提出了地图集，这是一个系统地评估人类运动轨迹预测算法的基准。 Atlas提供数据预处理功能，超参数优化，具有流行的数据集，并具有灵活性，可以进行设置和进行不充分的相关实验，以分析方法的准确性和鲁棒性。在ATLAS的示例应用中，我们比较了五个流行的模型和基于学习的预测指标，并发现，如果适当应用，基于物理的早期方法仍然具有竞争力。这样的结果证实了像Atlas这样的基准的必要性。
