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. http://cs231n.stanford.edu/reports/2024/pdfs/614.pdf
