Abstract

Pattern recognition applications and methods are important areas in modern data science. One of the conventional issues for the analysis is the selection of important signal eigenvalues from many eigenvalues dominated by randomness. However, appropriate theoretical reason for selection criteria is not indicated. In this paper, investigating eigenvalue distribution of large covariance matrix for data matrix, comprehensive discrimination method of signal eigenvalues from the bulk of eigenvalues due to randomness is investigated. Applying the discrimination method to weight matrix of three-layered neural network, the method is examined by handwritten character recognition example.
