Linear and Non-Linear Dimensional Reduction via Class Representatives for Text Classification
2006
IEEE International Conference on Data Mining. Proceedings
We address the problem of building fast and effective text classification tools. We describe a "representatives methodology" related to feature extraction and illustrate its performance using as vehicles a centroid based method and a method based on clustered LSI that were recently proposed as useful tools for low rank matrix approximation and cost effective alternatives to LSI. The methodology is very flexible, providing the means for accelerating existing algorithms. It is also combined with
