人类机器人相互作用(HRI)对于在日常生活中广泛使用机器人至关重要。机器人最终将能够通过有效的社会互动来履行人类文明的各种职责。创建直接且易于理解的界面,以与机器人开始在个人工作区中扩散时与机器人互动至关重要。通常,与模拟机器人的交互显示在屏幕上。虚拟现实(VR)是一个更具吸引力的替代方法,它为视觉提示提供了更像现实世界中看到的线索。在这项研究中,我们介绍了Jubileo,这是一种机器人的动画面孔,并使用人类机器人社会互动领域的各种研究和应用开发工具。Jubileo Project不仅提供功能齐全的开源物理机器人。它还提供了一个全面的框架,可以通过VR接口进行操作,从而为HRI应用程序测试带来沉浸式环境,并明显更好地部署速度。

先前的工作表明,深-RL可以应用于无地图导航,包括混合无人驾驶空中水下车辆(Huauvs)的中等过渡。本文介绍了基于最先进的演员批评算法的新方法,以解决Huauv的导航和中型过渡问题。我们表明,具有复发性神经网络的双重评论家Deep-RL可以使用仅范围数据和相对定位来改善Huauvs的导航性能。我们的深-RL方法通过通过不同的模拟场景对学习的扎实概括,实现了更好的导航和过渡能力,表现优于先前的方法。

深钢筋学习中的确定性和随机技术已成为改善运动控制和各种机器人的决策任务的有前途的解决方案。先前的工作表明,这些深-RL算法通常可以应用于一般的移动机器人的无MAP导航。但是,他们倾向于使用简单的传感策略,因为已经证明它们在高维状态空间(例如基于图像的传感的空间)方面的性能不佳。本文在执行移动机器人无地图导航的任务时,对两种深-RL技术 - 深确定性政策梯度(DDPG)和软参与者(SAC)进行了比较分析。我们的目标是通过展示神经网络体系结构如何影响学习本身的贡献,并根据每种方法的航空移动机器人导航的时间和距离提出定量结果。总体而言,我们对六个不同体系结构的分析强调了随机方法(SAC)更好地使用更深的体系结构,而恰恰相反发生在确定性方法(DDPG)中。

The field of robotics, and more especially humanoid robotics, has several established competitions with research oriented goals in mind. Challenging the robots in a handful of tasks, these competitions provide a way to gauge the state of the art in robotic design, as well as an indicator for how far we are from reaching human performance. The most notable competitions are RoboCup, which has the long-term goal of competing against a real human team in 2050, and the FIRA HuroCup league, in which humanoid robots have to perform tasks based on actual Olympic events. Having robots compete against humans under the same rules is a challenging goal, and, we believe that it is in the sport of archery that humanoid robots have the most potential to achieve it in the near future. In this work, we perform a first step in this direction. We present a humanoid robot that is capable of gripping, drawing and shooting a recurve bow at a target 10 meters away with considerable accuracy. Additionally, we show that it is also capable of shooting distances of over 50 meters.

Despite being responsible for state-of-the-art results in several computer vision and natural language processing tasks, neural networks have faced harsh criticism due to some of their current shortcomings. One of them is that neural networks are correlation machines prone to model biases within the data instead of focusing on actual useful causal relationships. This problem is particularly serious in application domains affected by aspects such as race, gender, and age. To prevent models from incurring on unfair decision-making, the AI community has concentrated efforts in correcting algorithmic biases, giving rise to the research area now widely known as fairness in AI. In this survey paper, we provide an in-depth overview of the main debiasing methods for fairness-aware neural networks in the context of vision and language research. We propose a novel taxonomy to better organize the literature on debiasing methods for fairness, and we discuss the current challenges, trends, and important future work directions for the interested researcher and practitioner.

Large language models (LLMs) have been shown to be able to perform new tasks based on a few demonstrations or natural language instructions. While these capabilities have led to widespread adoption, most LLMs are developed by resource-rich organizations and are frequently kept from the public. As a step towards democratizing this powerful technology, we present BLOOM, a 176B-parameter open-access language model designed and built thanks to a collaboration of hundreds of researchers. BLOOM is a decoder-only Transformer language model that was trained on the ROOTS corpus, a dataset comprising hundreds of sources in 46 natural and 13 programming languages (59 in total). We find that BLOOM achieves competitive performance on a wide variety of benchmarks, with stronger results after undergoing multitask prompted finetuning. To facilitate future research and applications using LLMs, we publicly release our models and code under the Responsible AI License.

变压器与卷积编码器结合使用,最近已使用微型多普勒特征用于手势识别(HGR)。我们为HGR提出了一个基于视觉转换器的架构,该体系结构具有多腹腔连续波多普勒雷达接收器。所提出的架构由三个模块组成:一个卷积编码器,带有三个变压器层的注意模块和一个多层感知器。新型的卷积解码器有助于将具有较大尺寸的斑块喂入注意力模块,以改善特征提取。用与两种抗连续波多普勒雷达接收器相对应的数据集获得的实验结果(Skaria等人出版)证实,所提出的体系结构的准确性达到了98.3%,从而实质上超过了现状的阶段。 - 在使用的数据集上进行艺术。

强化学习(RL)通过原始像素成像和连续的控制任务在视频游戏中表现出了令人印象深刻的表现。但是,RL的性能较差,例如原始像素图像,例如原始像素图像。人们普遍认为,基于物理状态的RL策略(例如激光传感器测量值)比像素学习相比会产生更有效的样品结果。这项工作提出了一种新方法,该方法从深度地图估算中提取信息,以教授RL代理以执行无人机导航(UAV)的无地图导航。我们提出了深度模仿的对比度无监督的优先表示(DEPTH-CUPRL),该表示具有优先重播记忆的估算图像的深度。我们使用RL和对比度学习的组合,根据图像的RL问题引发。从无人驾驶汽车(UAV)对结果的分析中,可以得出结论,我们的深度cuprl方法在无MAP导航能力中对决策和优于最先进的像素的方法有效。

使用胶囊网络的原始点云处理在分类,重建和分割中被广泛采用,因为它能够保留输入数据的空间协议。然而,基于现有的大多数基于胶囊的网络方法是计算繁重的,并且在将整个点云作为单个胶囊代表整个点云。我们通过提出具有参数共享的小说卷积胶囊架构,通过提出Pointcaps来解决现有的胶囊网络基础方法的这些限制。除了点击措施之外,我们提出了一种新颖的欧几里德距离路由算法和独立于独立的潜在潜在表示。潜在的表示捕获了点云的物理解释的几何参数,具有动态欧几里德路由,Pointcaps阱 - 代表点的空间(点对部分)关系。 Pointcaps的参数具有显着较低的参数,并且需要显着较低的拖鞋,同时实现与最先进的胶囊网络相比,对原始点云的可比分类和分割精度实现更好的重建。

AI正在经历范式转变,随着模型的兴起(例如Bert,Dall-E,GPT-3),这些模型经过大规模的数据训练,并且可以适应广泛的下游任务。我们称这些模型基础模型来强调其至关重要但不完整的特征。该报告提供了基础模型的机会和风险的详尽说明,包括其功能(例如语言,愿景,机器人技术,推理,人类互动)和技术原则(例如,模型架构,培训程序,数据,系统,安全,安全性,评估,理论)对其应用(例如法律,医疗保健,教育)和社会影响(例如不平等,滥用,经济和环境影响,法律和道德考虑)。尽管基础模型基于标准的深度学习和转移学习,但它们的规模导致了新的新兴能力,以及它们在许多任务中的有效性都激发了同质化。同质化提供了强大的杠杆作用,但要求谨慎,因为基础模型的缺陷均由下游的所有适应模型继承。尽管即将广泛地部署基础模型,但我们目前对它们的工作方式,失败以及由于其新兴属性的影响而缺乏清晰的了解。为了解决这些问题,我们认为基础模型的许多批判性研究都需要与他们的基本社会技术性质相称。
