[0027] For deep semi-non-negative matrix factorization (Deep Semi-NMF), the original dataset matrix Y that does not limit the positive and negative internal elements is given ± Decompose into (m+1) factors, so that the product of these (m+1) factors is as close as possible to the original data set matrix Y ± approximately equal. Under the limitation of non-negative coefficient matrix, deep semi-non-negative matrix regularization keeps information unchanged as much as possible, an...

Abstract

The invention provides a local learning regularization-based depth matrix decomposition method and an image clustering method, wherein the depth matrix decomposition method comprises the steps of S10obtaining a data matrix Y according to a picture to be clustered; S20 constructing an objective function based on the data matrix Y S30 using an iterative weighting method according to the objective function C to output a basis matrix Ni and a coefficient matrix Mi to complete the decomposition of the data matrix Y. Compared with the traditional absolute non-negative matrix factorization, not onlythe deep semi-non-negative matrix factorization is used to classify the data accurately and efficiently, but also some attribute information is combined to minimize the prediction cost of each region.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a deep matrix decomposition method and an image clustering method based on local learning regularization. Background technique [0002] In many cases, in order to deal with data classification and clustering problems, we often face the problem of dealing with high-dimensional data. The conventional solution to this kind of problem is to reduce the high-dimensional data, that is, to establish a certain data representation method, and use the low-dimensional data to approximate the high-dimensional data. Commonly used data representation methods are mainly divided into two categories: one is a linear representation method, and the other is a nonlinear representation method. For the linear representation method, only the low-dimensional manifold where the sampling data is located is linear, which is easy to use, but when the original data is linearly decomposed, the potent...
