Deep Reinforcement Learning in Robotics Figure 1: SURREAL is an open-source framework that facilitates reproducible deep reinforcement learning (RL) research for robot manipulation. We implement scalable reinforcement learning methods that can learn from parallel copies of physical simulation. We also develop Robotics Suiteof reinforcement learning was the novel concept of a deep Q-network, which combines Q-learning in with neural net-works and experience replay to decorrelate states and up-date the action-value function. After being trained with a deep Q-network, the DeepMind agent was able to outper-form humans on nearly 85% Breakout games [4].

Recently there has been growing interest in extending RL to the multi-agent domain. From the technical point of view,this has taken the community from the realm of Markov Decision Problems (MDPs) to the realm of gameReinforcement Learning (RL) RL: algorithms for solving MDPs with incomplete information of M (e.g., p, r accessible by interacting with the environment) as input. Today:fully online(no simulator),episodic(allow restart in the trajectory) andmodel-free(no storage of transition & reward models). ZKOB20 (Stanford University) 5 / 30A Survey on Reinforcement Learning Methods in Character Animation.

While learning, they repeatedly take actions based on their observation of the environment, …ENGINEERING INTERACTIVE LEARNING IN ARTIFICIAL SYSTEMS. We look to develop machines that learn through autonomous exploration of and interaction with their environments -- as humans learn. To do this, we use deep reinforcement learning and employ and develop techniques in curiosity, active learning, and self-supervised learning.Beyond the anthropomorphic motivation presented above, improving autonomy for robots addresses the long-standing challenge of lack of large robotic interaction datasets. While learning from data collected by experts (“demonstrations”) can be effective for learning complex skills, human-supervised robot data is very expensive …This course is complementary to CS234: Reinforcement Learning with neither being a pre-requisite for the other. In comparison to CS234, this course will have a more applied and deep learning focus and an emphasis on use-cases in robotics and motor control. Topics Include. Methods for learning from demonstrations.
