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 ...

WebOct 16, 2024 · Autonomous driving is a complex task, which has been tackled since the first self-driving car ALVINN in 1989, with a supervised learning approach, or behavioral cloning (BC). In BC, a neural network is trained with state-action pairs that constitute the training set made by an expert, i.e., a human driver. However, this type of imitation learning does … 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.
