Unsupervised graph-based feature selection via subspace and pagerank centrality

作者:

Highlights:

• Features that discriminate classes are linked to provide an undirected graph.

• Features relationships are defined based on unsupervised subspace learning.

• PageRank is investigated to rank features according to their importance in graph.

• High dimension low sample data are used to assess and compare the proposed method.

• The proposed unsupervised graph based method outperforms competitive methods.
