免疫进化的投影寻踪模型在文本分类中的应用
Projection Pursuit Model of Immune Evolution and Its Application to Text Classification
摘要
Abstract
Projection pursuit is used to find the projection direction which reflect the intrinsic structure and features of the original data. So the high dimensional data can be studied and analyzed through lower dimensional space. For the curse of dimensionality in text classification, the multi-dimensional data is turned into low-dimensional space by using projection pursuit model. The nature of the problem is that it is difficult to determine the direction of projection pursuit and the calculation is not easy,especially when the projection direction has more indicators. This paper proposed the projection pursuit model using immune evolution algorithm, which can effectively solve the optimization problem of the projection direction. In the experiment,it's applied to text classification including the Reuters-21578 document sets and FuDan document sets. The experimental results show that this method can not only solve the curse of dimensionality in text classification,but also obtain a satisfactory classification results.关键词
