Interactive Deep RL Demo
A demo where agents trained by deep reinforcement learning — a bipedal walker, a chimpanzee, a fish — are dropped into different terrains so you can watch how they move. Besides the prepared environments, you can draw the ground and ceiling yourself and put the agents into situations they never saw during training. You come away seeing the generalization problem first-hand: learned behaviour works well in familiar surroundings and can fall apart when the environment changes.
How to try it
Under 'Getting Started', load one of the prepared environments — flat ground, a course with creepers for the chimpanzee, a hard parkour, or an underwater one — and press run to set the agent moving. In 'Terrain Generation' the Ground and Ceiling buttons let you draw terrain with the mouse; press 'Generate Terrain' to test the same agents in it, and adjust settings such as water level and creepers. The interface is English and French only, and a physics simulation runs continuously, so a desktop browser is recommended.
