Witryna17 maj 2024 · In such scenarios, online exploration is simply too risky, but offline RL methods can learn effective policies from logged data collected by humans or heuristically designed controllers. Prior learning-based control methods have also approached learning from existing data as imitation learning: if the data is generally … WitrynaAbstract. Learning an informative representation with behavioral metrics is able to accelerate the deep reinforcement learning process. There are two key research issues on behavioral metric-based representation learning: 1) how to relax the computation of a specific behavioral metric, which is difficult or even intractable to compute, and 2 ...

WitrynaConsider learning a policy from example expert behavior, without interaction with the expert or access to a 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. This approach is indirect and can be slow. Witryna16 wrz 2024 · To achieve this target, we extend the problem of imitation learning and transform it into a reinforcement learning (RL) framework with an MDP, with 5-tuple {State S, Action A, Reward R, Transition Probability P, Discount Rate γ}.
