Dagger imitation learning
WebMar 1, 2024 · In this paper, we propose MEGA-DAgger, a new DAgger variant that is suitable for interactive learning with multiple imperfect experts. First, unsafe demonstrations are filtered while aggregating the training data, so the imperfect demonstrations have little influence when training the novice policy. Next, experts are evaluated and compared on ... WebMar 1, 2024 · However, existing interactive imitation learning methods assume access to one perfect expert. Whereas in reality, it is more likely to have multiple imperfect experts …

DAgger is one of the most-used imitation learning algorithms. Let's understand how DAgger works with an example. Let's revisit our example of training an agent to drive a car. First, we initialize an empty dataset . In the first iteration, we start off with some policy to drive the car. Thus, we generate a trajectory using the policy .
