Amazon debuts a scale model autonomous car to teach developers machine learning

Amazon today announced AWS DeepRacer, a fully autonomous 1/18th-scale race car that aims to help developers learn machine learning. Priced at $399 but currently offered for $249, the race car lets developers get hands-on — literally — with a machine learning technique called reinforcement learning (RL).
RL takes a different approach to training models than other machine learning techniques, Amazon explained.
