Abstract

Abstract: The NMF method is applied to Chinese character and some base structures are discovered successfully.By introducing punishment factor into target function，a expended NMF method is proposed which is more suitable to factorize Chinese characters.

Key words: Nonnegative Matrix Factorization（NMF）, Chinese characters, base component

摘要： 将NMF方法应用到汉字字形的处理中，成功地从一些汉字样本中抽取出构成这些汉字的基本部件。通过引入合适的惩罚因子，提出了一种扩展的NMF方法，对同样的汉字样本进行处理可以获得更好的结果，抽取出的基本部件就是构成这些汉字的偏旁部首。
