Websuch a system employing hierarchical Bayesian inference to combine sensory input at the lowest levels with feedback from priors higher up [7]. Models have been developed based on the idea of sparse coding that seem to mimic many of the observed features of area V1 … WebRecently, sparse representation (SR) methods (dictionary learning and coding) have been introduced for signature modeling and verification with promising results. In this paper, we propose an extension of the SR framework by introducing the idea of embedding the atoms of a dictionary in a directed tree.
