WebDAgger. 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 . WebOct 5, 2024 · HG-DAgger is proposed, a variant of DAgger that is more suitable for interactive imitation learning from human experts in real-world systems and learns a safety threshold for a model-uncertainty-based risk metric that can be used to predict the performance of the fully trained novice in different regions of the state space. Imitation …
WebUsing only the expert trajectories would result in a model unable to recover from non-optimal positions; Instead, we use a technique called DAgger: a dataset aggregation technique with mixed policies between expert and model. Quick start. Use the jupyter notebook notebook.ipynb to quickly start training and testing the imitation learning Dagger. WebImitation learning algorithms aim at learning controllers from demonstrations by human experts (Schaal,1999;Abbeel,2008;Syed,2010). Unlike standard reinforcement learning ...
