由于在存在障碍物和高维视觉观测的情况下，由于在存在障碍和高维视觉观测的情况下，学习复杂的操纵任务是一个具有挑战性的问题。事先工作通过整合运动规划和强化学习来解决勘探问题。但是，运动计划程序增强策略需要访问状态信息，该信息通常在现实世界中不可用。为此，我们建议通过（1）视觉行为克隆以通过（1）视觉行为克隆来将基于国家的运动计划者增强策略，以删除运动计划员依赖以及其抖动运动，以及（2）基于视觉的增强学习来自行为克隆代理的平滑轨迹的指导。我们在阻塞环境中的三个操作任务中评估我们的方法，并将其与各种加固学习和模仿学习基线进行比较。结果表明，我们的框架是高度采样的和优于最先进的算法。此外，与域随机化相结合，我们的政策能够用零击转移到未经分散的人的未经环境环境。 https://clvrai.com/mopa-pd提供的代码和视频

We propose an ensemble approach to predict the labels in linear programming word problems. The entity identification and the meaning representation are two types of tasks to be solved in the NL4Opt competition. We propose the ensembleCRF method to identify the named entities for the first task. We found that single models didn't improve for the given task in our analysis. A set of prediction models predict the entities. The generated results are combined to form a consensus result in the ensembleCRF method. We present an ensemble text generator to produce the representation sentences for the second task. We thought of dividing the problem into multiple small tasks due to the overflow in the output. A single model generates different representations based on the prompt. All the generated text is combined to form an ensemble and produce a mathematical meaning of a linear programming problem.

Spatial perception is a key task in several robotics applications. In general, it involves the nonlinear estimation of hidden variables that represent the state of the robot/environment. However, in the presence of outliers the standard nonlinear least squared formulation results in poor estimates. Several methods have been considered in the literature to improve the reliability of the estimation process. Most methods are based on heuristics since guaranteed global robust estimation is not generally practical due to high computational costs. Recently general purpose robust estimation heuristics have been proposed that leverage existing non-minimal solvers available for the outlier-free formulations without the need for an initial guess. In this work, we propose two similar heuristics backed by Bayesian theory. We evaluate these heuristics in practical scenarios to demonstrate their merits in different applications including 3D point cloud registration, mesh registration and pose graph optimization.

Low-rank and sparse decomposition based methods find their use in many applications involving background modeling such as clutter suppression and object tracking. While Robust Principal Component Analysis (RPCA) has achieved great success in performing this task, it can take hundreds of iterations to converge and its performance decreases in the presence of different phenomena such as occlusion, jitter and fast motion. The recently proposed deep unfolded networks, on the other hand, have demonstrated better accuracy and improved convergence over both their iterative equivalents as well as over other neural network architectures. In this work, we propose a novel deep unfolded spatiotemporal RPCA (DUST-RPCA) network, which explicitly takes advantage of the spatial and temporal continuity in the low-rank component. Our experimental results on the moving MNIST dataset indicate that DUST-RPCA gives better accuracy when compared with the existing state of the art deep unfolded RPCA networks.

室内运动计划的重点是解决通过混乱环境导航代理的问题。迄今为止，在该领域已经完成了很多工作，但是这些方法通常无法找到计算廉价的在线路径计划和路径最佳之间的最佳平衡。除此之外，这些作品通常证明是单一启动单目标世界的最佳性。为了应对这些挑战，我们为在未知室内环境中进行导航的多个路径路径计划者和控制器堆栈，在该环境中，路点将目标与机器人必须在达到目标之前必须穿越的中介点一起。我们的方法利用全球规划师（在任何瞬间找到下一个最佳航路点），本地规划师（计划通往特定航路点的路径）以及自适应模型预测性控制策略（用于强大的系统控制和更快的操作） 。我们在一组随机生成的障碍图，中间航路点和起始目标对上评估了算法，结果表明计算成本显着降低，具有高度准确性和可靠的控制。

我们对深度学习的理论理解并没有与其经验成功保持同步。尽管已知网络体系结构至关重要，但我们尚不了解其对学习的表示和网络行为的影响，或者该体系结构如何反映任务结构。在这项工作中，我们开始通过引入门控的深层线性网络框架来解决此差距。这阐明了信息流的路径如何影响体系结构内的学习动态。至关重要的是，由于门控，这些网络可以计算其输入的非线性函数。我们得出了精确的减少，并且在某些情况下，我们可以确切解决学习动力学的方法。我们的分析表明，结构化网络中的学习动态可以概念化为具有隐性偏见的神经种族，然后控制模型的系统概括，多任务和转移的能力。我们通过自然主义数据集并使用轻松的假设来验证我们的关键见解。综上所述，我们的工作提出了将神经体系结构与学习有关的一般假设，并提供了一种数学方法，以理解更复杂的架构的设计以及模块化和组成性在解决现实世界中问题中的作用。代码和结果可在https://www.saxelab.org/gated-dln上找到。
