摘要 提出一种基于流形学习的文本分类方法以解决高维文本数据分类问题。利用近邻保持嵌入流形学习算法获得高维Web文本空间中的低维流形结构,采用K近邻分类器对低维流形进行分类。实验结果表明,基于流形学习的方法能获得较好的分类效果,具有稳定的性能。 To efficiently resolve the high dimensional Web text classification problem,a novel classification algorithm is proposed in this paper on the basis of manifold learning.The algorithm can explore and preserve the inherent structure on high dimensional Web text space,and the classification and predication in the lower dimension feature space are implemented with K-Nearest Neighbor（KNN）.Experimental results show that the algorithm achieves higher classification accuracy and stability.
