Shaping and policy search for nearest-neighbour control policies with applications to vehicle steering [article]

Ken Alton
Direct policy search is applied to a nearest-neighbour control policy, which uses a Voronoi cell discretization of the observable state space, as induced by a set of control nodes located in this space  ...  We examine these motion control results critically and discuss the limitations of the nearest-neighbour policy representation and our policy search method.  ...  She has shown that a similar policy search method can be used to learn policies for planar biped walking, which I find very exciting. Much of this work has been supported by a NSERC PGS-A scholarship.  ...
