Sparsification of Linear Models for Large-Scale Text Classification

Abstract : In this paper we propose a simple yet effective method for sparsifying a posteriori linear models for large-scale text classification. The objective is to maintain high performance while reducing the prediction time by producing very sparse models. This is especially important in real-case scenarios where one deploys predictive models in several machines across the network and constraints apply on the prediction time. We empirically evaluate the proposed approach in a large collection of documents from the Large-Scale Hierarchical Text Classification Challenge. The comparison with a feature selection method and LASSO regularization shows that we achieve to obtain a sparse representation improving in the same time the classification performance.
