Kullback-Leibler Principal Component for Tensors is not NP-hard
Kejun Huang, Nicholas D. Sidiropoulos
We study the problem of nonnegative rank-one approximation of a nonnegative tensor, and show that the globally optimal solution that minimizes the generalized Kullback-Leibler dive…
On Convergence of Epanechnikov Mean Shift
Kejun Huang, Xiao Fu, Nicholas D. Sidiropoulos
Epanechnikov Mean Shift is a simple yet empirically very effective algorithm for clustering. It localizes the centroids of data clusters via estimating modes of the probability dis…
Completing a joint PMF from projections: a low-rank coupled tensor factorization approach
Nikos Kargas, Nicholas D. Sidiropoulos
There has recently been considerable interest in completing a low-rank matrix or tensor given only a small fraction (or few linear combinations) of its entries. Related approaches…
