In the paradigm of Reinforcement Learning (RL), an agent learns from the reward feedback when interacting with the environment. However, it remains a challenge to design proper reward functions for complex tasks in real life. To that end, Imitation Learning (IL), also known as Learning from Demonstration (LfD), acts as an alternative method to learn policies without any reward signal and make better use of existed exert demonstrations. Besides, it is observed both theoretically and empirically that IL can help agent learn a sub-optimal policy in a more data-efficient way than RL. Not only for single-agent tasks, IL also helps agents learn in multi-agent settings, where the expert demonstrations are interactions among agents. Our workshop is a half-day workshop on Imitation Learning at DAI 2020, with the aim to provide a venue, which can bring together academia researchers and industry practitioners (i) to discuss the principles, limitations and applications of IL for both single-agent and multi-agent scenarios, and (ii) to foster research on innovative algorithms, novel techniques, and new applications of IL.
