aoc.m 是用matlab实现蚁群算法ants_information.m蚁群算法中信息素的构建 mcl是马尔科夫聚类算法 nmf是矩阵的非负分解 Generative Topographic Mapping工具包-aoc.m is matlab implementation of ant colony algorithm ants_information.m pheromone ant colony algorithm is a Markov clustering algorit

svd和nmf的对比，在时间和效果对比，各个算法的特点-svd VS nmf

主要实现非负矩阵的有效分解，其中有详细的解释，以及什么样的矩阵才能适合该算法(realize the matrix factorization with non-negative matrix)

DNMF实现了NMF延展的功能，是基于NMF的一种创新算法(Discriminant Non-Negative Matrix Factorization aims to extend the Non-negative Matrix Factorization algorithm in order to extract features that enforce not only the spatial locality, but also the separability between cla
