Elastic nonnegative matrix factorization
作者:
Highlights:
• ENMF introduces an elastic loss that takes advantage of both Frobenius norm and ℓ2, 1 norm when noise distribution is uncertain, therefore ENMF is far more insensitive to noise and outliers.
• ENMF takes the geometric information of the projected data points in the low dimensional manifold as feedback to construct the affinity graph, hence ENMF can handle the situation that a few exceptional data pairs are close in the original space but far away from each other in the manifold.
• ENMF utilizes the exclusive LASSO to enhance the intra-cluster competition and therefore the “winner” is more likely to stand out while the “loser” tends to be out in a sparse manner.
• ENMF provides consistently better clustering results on several well-known data sets as compared to standard NMF and several other variants of the NMF algorithm.
