Title: The Dimension of NMF Initialization Matrix Based on SVD
Abstract: Based on the properties of singular value decomposition and singular value, the method of determining the initial matrixdimension of non negative matrix factorization is proposed. The contribution rate of the matrix singular value is calculated. To avoidthe defect of the dimension of human attempt. The rationality of the method is given. A comparison is made on the different methods of determining the initial matrix dimension using the singular values, and it is proved that the size of the initial matrix dimension is required for the same contribution rate.
