My Research

Hi! I’m Anthony Francis, and I design intelligent machines and emotional robots, focusing on deep reinforcement learning for indoor robot navigation. My original research page http://www.dresan.com/research/ details my thesis work on contextual memory. More recently, I’ve focused on robotics, first emotional robotics and later robot navigation. More information can be found in the subpages below:

I currently work for Robotics at Google, focusing on robotics for reinforcement learning and reinforcement learning for robotics. Our work involves making robot navigation more reliable using approaches that combine deep reinforcement learning, evolutionary computation, and “traditional” probabilistic motion planning approaches which were the snazzy new thing when I started my PhD work, and which still do the job pretty well now.

My PhD research focused on contextual memory: how implicit context helps us retrieve and use information more appropriately. This can include not just memory for facts, but memory for emotion: annotating experiences with the emotions they cause can be used to learn emotional responses that are appropriate for different situations.

My other research interests include programming language design, interactive fiction, natural language understanding, animal cognition, cognitive science, intelligent agents, and physics, particularly general relativity. For more information, check out the subpages, or read recent posts below:
