<p class="MsoNormal" style="line-height:normal;margin:0in 0in 10pt">For
autonomous robots to operate in the open, dynamically changing world, they
will need to be able to learn a robust set of interacting skills. This talk begins by introducing "Overlapping Layered Learning"
as a novel hierarchical machine learning paradigm for learning such
interacting skills in simulation. While learning in simulation is appealing because it avoids the prohibitive sample cost of
learning in the real world, unfortunately policies learned in simulation
often fail when applied on physical robots. This talk then introduces
"Grounded Simulation Learning" to address this problem by algorithmically
altering the simulator to better match the real world, and connects this new
algorithm to a theoretical analysis of off-policy evaluation in
reinforcement learning. Overlapping Layered Learning was the key
deciding factor in UT Austin Villa's RoboCup robot soccer 3D simulation
league championship, and Grounded Simulation Learning has led to the
fastest known stable walk on a widely used humanoid robot.<span></span></p>
