Policy Improvement for POMDPs Using Normalized Importance Sampling
(2001-03-20)We present a new method for estimating the expected return of a POMDP from experience. The estimator does not assume any knowle ge of the POMDP and allows the experience to be gathered with an arbitrary set of policies. ... -
Observations on Cortical Mechanisms for Object Recognition andsLearning
(1993-12-01)This paper sketches a hypothetical cortical architecture for visual 3D object recognition based on a recent computational model. The view-centered scheme relies on modules for learning from examples, such as Hyperbf-like ... -
Geometric and Algebraic Aspects of 3D Affine and Projective Structures from Perspective 2D Views
(1993-07-01)We investigate the differences --- conceptually and algorithmically --- between affine and projective frameworks for the tasks of visual recognition and reconstruction from perspective views. It is shown that an affine ...
