Generative Adversarial Imitation Learning. Consider learning a policy from example expert behavior, without interaction with the expert or access to reinforcement signal. One approach is to recover the expert's cost function with inverse reinforcement learning, then extract a policy from that cost function with reinforcement learning.

Imitation learning is an AI process of learning by observing an expert, and has been recognized as a powerful approach for sequential decision-making, with diverse applications like healthcare, autonomous driving and complex game playing. However, conventional imitation learning methodologies often utilize behavioral cloning, which has ...Jul 2, 2020 · 5.1 Imitation Learning. Imitation learning is the second main class of models for learning from demonstrations. Unlike inverse reinforcement learning, imitation learning does not attempt to recover a reward function of an agent, but rather attempts to directly model the action policy given an observed behavior.

Definition. Imitation can be defined as the act of copying, mimicking, or replicating behavior observed or modeled by other individuals. Current theory and research emphasize that imitation is not mechanical “parroting,” but complex, goal-oriented behavior which is central to learning. Repetition is closely linked to imitation.

Imitation learning from demonstrations (ILD) aims to alleviate numerous short-comings of reinforcement learning through the use of demonstrations. However, in most real-world applications, expert action guidance is absent, making the use of ILD impossible. Instead, we consider imitation learning from observations (ILO),Imitation Learning is a form of Supervised Machine Learning in which the aim is to train the agent by demonstrating the desired behavior. Let’s break down that definition a bit. …Deep imitation learning: using a deep neural network to extract such knowledge One concern: The sensory system of a human demonstrator is different from a machine’s –Humans have foveal vision with high acuity for only 1-2 visual degrees Figure 1: Foveal vision.
