Evaluating the performance of deep supervised auto encoder in single sample face recognition problem using Kullback-Leibler Divergence sparsity regularizer

Recent development on supervised auto encoder research gives promising solutions toward single sample face recognition problems. In this research, Kullback-Leibler Divergence (KLD) approach is proposed to obtain penalty of sparsity constraint for deep auto encoder learning process. This approach is tested using two datasets, Extended Yale B (cropped version) and LFWcrop. For comparison, Log and εL₁also employed as sparsity regularizers. Experiment results confirm that KLD has better performance in image classification of both datasets compared to Log and εL₁.
