Exploring Imitation Learning for Autonomous Driving with Feedback Synthesizer and Differentiable Rasterization

IROS 2021poster

We present a learning-based planner that aims to robustly drive a vehicle by mimicking human drivers’ driving behavior. We leverage a mid-to-mid approach that allows us to manipulate the input to our imitation learning network freely. With that in mind, we propose a novel feedback synthesizer for da…
