Hidden Markov models (hmms) and partially observable Markov decision
processes (pomdps) provide useful tools for modeling dynamical systems.
They are particularly useful for representing the topology of environments
such as road networks and office buildings, which are typical for
robot navigation and planning. The work presented here describes
a formal framework for incorporating readily available odometric
information and geometrical constraints into both the models and
the algorithm that learns them. By taking advantage of such information,
learning hmms/pomdps can be made to generate better solutions and
require fewer iterations, while being robust in the face of data
reduction. Experimental results, obtained from both simulated and
real robot data, demonstrate the effectiveness of the approach.
