Teleoperating a robot for complex and intricate tasks demands a high mental workload from a human operator. Deploying multiple operators can mitigate this problem, but it can be also a costly solution. Learning from Demonstrations can reduce the human operator’s burden by learning repetitive teleoperation tasks. Yet, the demonstrations via teleoperation tend to be inconsistent compared to other modalities...
Task-parameterized skill learning aims at adaptive motion encoding to new situations. While existing approaches for task-parameterized skill learning have demonstrated good adaptation within the demonstrated region, the extrapolation problem of task-parameterized skills has not been investigated enough. In this work, with the aim of good adaptation not only within the demonstrated region but also...
While teleoperation provides a possibility for a robot to operate at extreme conditions instead of a human, teleoperating a robot still demands a heavy mental workload from a human operator. Learning from demonstrations can reduce the human operator's burden by learning repetitive teleoperation tasks. However, one of challenging issues is that demonstrations via teleoperation are less consistent compared...
In learning by exploration problems such as reinforcement learning (RL), direct policy search, stochastic optimization or evolutionary computation, the goal of an agent is to maximize some form of reward function (or minimize a cost function). Often, these algorithms are designed to find a single policy solution. We address the problem of representing the space of control policy solutions by considering...
