Sparse Representations of Multiple Signals
(1997-09-01)We discuss the problem of finding sparse representations of a class of signals. We formalize the problem and prove it is NP-complete both in the case of a single signal and that of multiple ones. Next we develop a simple ... -
Belief Propagation and Revision in Networks with Loops
(1997-11-01)Local belief propagation rules of the sort proposed by Pearl(1988) are guaranteed to converge to the optimal beliefs for singly connected networks. Recently, a number of researchers have empirically demonstrated good ... -
Visual Recognition and Categorization on the Basis of Similarities to Multiple Class Prototypes
(1997-09-01)To recognize a previously seen object, the visual system must overcome the variability in the object's appearance caused by factors such as illumination and pose. Developments in computer vision suggest that it may be ...
