WebMay 1, 2024 · To address issues of safety both during and after learning, we developed the Human-Gate DAgger (HG-DAgger) algorithm (Kelly et al. 2024). HG-DAgger uses Bayesian deep imitation learning and gives ... WebAlthough imitation learning is often used in robotics, the approach frequently suffers from data mismatch and compounding errors. DAgger is an iterative algorithm that addresses these issues by aggregating training data from both the expert and novice policies, but does not consider the impact of safety.
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 …
