在过去的十年中,水下事物的互联网(IOUT)在环境监测和勘探,国防应用等应用程序中取得了迅速的动力。传统的IOUT系统使用机器学习(ML)方法,这些方法满足了可靠性,效率和及时性的需求。但是,对进行的各种研究的广泛审查突出了IOUT框架中数据隐私和安全性的重要性,这是实现任务关键应用程序中预期结果的主要因素。联邦学习(FL)是一个有安全的,分散的框架,是机器学习的最新发展,它将有助于满足IOUT中常规ML方法所面临的挑战。本文概述了FL在IOUT中的各种应用,其挑战,开放问题并指示未来研究前景的方向。

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.

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。
