Model-based imitation refers to a family of machine-learning methods, which can be used to quickly generate a rough solution to a given control task, usually in robotics, using demonstrated behavior. The premise is that a large class of tasks can be demonstrated, either by a human, e.g., household tasks for domestic robots, or by ... Nov 1, 2022 · In imitation learning (IL), an agent is given access to samples of expert behavior (e.g. videos of humans playing online games or cars driving on the road) and it tries to learn a policy that mimics this behavior.
