Title: Planning in Uncertain Worlds: Exploration and Information
Gather

ing

Talk Abstract:
Decision making in uncertain and incomplete mo

dels is an
essential capability of robots operating in natural dynamic

domains. Separating model learning and planning into two
distinct
processes simplifies both problems but prevents
the planner from deli

berately learning more to improve its
own performance. In my group we h

ave developed two
approaches for planning in the information space of m

odels;
these algorithms allow a robot to generate plans that are
r

obust to model errors while planning to learn more about the
world. I w

ill present results of our work in the domains of robot
navigation and

human-robot dialogue management.
