IRL may be useful for apprenticeship learning to acquire skilled behavior, and for ascertaining the reward function being optimized by a natural system.To meet the demands of such applications that require quickly learning or adapting to new tasks, this thesis focuses on meta-reinforcement learning (meta-RL). Specifically we consider a setting where the agent is repeatedly presented with new tasks, all drawn from some related task family. The agent must learn each new task in only a few shots ...

3.1. Deep Reinforcement Learning In reinforcement learning, an agent interacting with its environment is attempting to learn an optimal control pol-icy. At each time step, the agent observes a state s, chooses an action a, receives a reward r, and transitions to a new state s0. Q-Learning is an approach to incrementally esti- of 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]. However, Emma Brunskill.

Control policies for soft robot arms typically assume quasi-static motion or require a hand-designed motion plan. To achieve real-time planning and control for tasks requiring highly dynamic maneuvers, we apply deep reinforcement learning to train a policy entirely in simulation, and we identify strategies and insights that bridge the gap between simulation … We introduce RoboNet, an open database for sharing robotic experience, and study how this data can be used to learn generalizable models for vision-based robotic manipulation. We find that pre-training on RoboNet enables faster learning in new environments compared to learning from scratch. The Stanford AI Lab (SAIL) Blog is a place for SAIL ...
