In their native …This process of learning from demonstrations, and the study of algorithms to do so, is called imitation learning. This work provides an introduction to imitation … Imitative learning is a type of social learning whereby new behaviors are acquired via imitation. [1] Imitation aids in communication, social interaction, and the ability to modulate one's emotions to account for the emotions of others, and is "essential for healthy sensorimotor development and social functioning". [1] The establishment of social imitation and patterns is vital to the survival of a species and to the development of a child, and plays an important role in our understanding of the social nature of human learning as a whole. Williamson, R. A.; Jaswal, V. K.; Meltzoff, A. N. Learning the rules: Observation and imitation of a sorting strategy by ... 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 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.
