Model Imitation for Model-Based Reinforcement Learning

WitrynaThe insight of using imitation learning as a way to bootstrap RL has been previously leveraged by a number of deep RL algorithms (Rajeswaran et al., Zhu et al., Nair et al.), where a flat imitation learning initialization is improved using reinforcement learning with additional auxiliary objectives. In this work, we show that we can learn ... Witryna3 lip 2024 · The integration of reinforcement learning (RL) and imitation learning (IL) is an important problem that has long been studied in the field of intelligent robotics. RL optimizes policies to maximize the cumulative reward, whereas IL attempts to extract general knowledge about the trajectories demonstrated by experts, i.e, demonstrators.
