Xiang Gao,

Abstract: Non-negative Tucker decomposition (NTD) is one of the renowned technique in feature extraction and representation for non-negative high-dimensional tensor data. The main focus behind NTD is how to factorize the data to get hold of a high quality data representation from multidimensional directions. However, NTD does not conserve the geometrical structure of the data space and does not consider relationship and property among columns of the factor matrices. In this paper, by using approximately orthogonal const… Show more
