Imitation Learning for Vision-based Lane Keeping Assistance Christopher Innocenti , Henrik Linden´ , Ghazaleh Panahandeh, Lennart Svensson, Nasser Mohammadiha Abstract—This paper aims to investigate direct imitation learn-ing from human drivers for the task of lane keeping assistance in highway and country roads using grayscale images from a single front view camera. How can we make it work more often? Imitation learning is useful when it is easier for the expert to demonstrate the desired behavior rather than: a) coming up with a reward function that would generate such behavior, b) coding up with the desired policy directly. steering angle, speed, etc. cuML integrates with other RAPIDS projects to implement machine learning algorithms and mathematical primitives functions.In most cases, cuML’s Python API matches the API from sciKit-learn.The project still has some limitations (currently the instances of cuML RandomForestClassifier cannot be pickled for example) but they have a short 6 … Setup Training Environment for Imitation Learning. Imitation learning can improve the efficiency of the learning process, by mimicking how humans or even other AI algorithms tackle the task. Imitation learning •Nvidia Dave-2 neural network Bojarski, Mariusz, et al. The sample complexity is manageable. Does direct imitation work? Deep Reinforcement : Imitation Learning 4 minute read Deep Reinforcement : Imitation Learning. yatzmon@nvidia.com, gchechik@nvidia.com, Abstract People easily recognize new visual categories that are new combinations of known components. Learned policies not only transfer directly to the real world (B), but also outperform state-of-the-art end-to-end methods trained using imitation learning. Imitation Learning ! A feasible solution to this problem is imitation learning (IL). Bayesian reward learning from demonstrations enables rigorous safety and uncertainty analysis when performing imitation learning.However, Bayesian reward learning methods are typically computationally intractable for complex control problems.
