摘要:
针对文本分类问题及投影寻踪降维的特点,对投影寻踪模型中投影指标进行改进,给出了新的投影指标.对不同的投影指标进行相应的对比实验,实验结果表明:改进的指标不仅充分利用投影寻踪降到超低维的特点,而且对文本分类的性能有了较大地提高.
Abstract:
Based on the text classification problem and PP features,the projection index of PP model has been improved.The projection index has been comparative experiment,the experimental results show that the projection index not only has made full use of projection pursuit to ultra low dimensional characteristics,but also has been improved greatly on the performance of text classification.
