NMF with feature relationship preservation penalty term for clustering problems

作者:

Highlights:

• Add the relationship between the data scatter and that of the centroids to the cost function of the NMF model.

• The update of W becomes parameterizable.

• The convergence towards the cluster centers is improved.

• The proposed method outperforms the existing orthogonal NMF methods.
