In Imitation learning (IL), robotic arms can learn manipu-lative tasks by mimicking the actions demonstrated by human experts. One mainstream approach within IL is Behavioral Cloning (BC), which involves learning a function that maps observations to actions from an expert’s demonstrations using supervised learning [1], [2]. Imitation learning and inverse RL. Imitation learning is a process of learning from demonstrations, also known as “apprenticeship learning”. It is motivated by the following question: If the agent has no idea about the reward, how can the agent learn about the environment to find the best policy? Imitation Bootstrapped Reinforcement Learning. Hengyuan Hu, Suvir Mirchandani, Dorsa Sadigh.

The most obvious limitation is the requirement of demonstration data or some way to obtain a supervised signal of desired behavior. Imitation learning is the study of algorithms that attempt to improve performance by mimicking a teacher’s decisions and behaviors. Such techniques promise to enable effective “programming by demonstra-tion” to automate tasks, such as driving, that people can demonstrate but find difficult to hand program. Imitation Learning from human demonstrations is a promising paradigm to teach robots manipulation skills in the real world, but learning complex long-horizon tasks often requires an unattainable amount of demonstrations. To reduce the high data requirement, we resort to human play data — video sequences of people freely interacting with the ...
