Excerpt

In machine learning and pattern recognition, feature selection has been a very active topic in the literature. Unsupervised feature selection is challenging due to the lack of label which would supply the categorical information. How to define an appropriate metric is the key for feature selection. In this paper, we propose a “filter” method for unsupervised feature selection, which is based on the geometry properties of ℓ 1 graph. ℓ 1 graph is constructed through sparse coding. The graph establishes the relations of feature subspaces and the …
