Jordan structures of nilpotent matrices in the centralizer of a nilpotent matrix with two Jordan blocks of the same size
Duško Bogdanić, Alen Đurić, Sara Koljančić +2
In this paper we characterize all nilpotent orbits under the action by conjugation that intersect the nilpotent centralizer of a nilpotent matrix consisting of two Jordan block…
SMIXS: Novel efficient algorithm for non-parametric mixture regression-based clustering
Peter Mlakar, Tapio Nummi, Polona Oblak +1
We investigate a novel non-parametric regression-based clustering algorithm for longitudinal data analysis. Combining natural cubic splines with Gaussian mixture models (GMM), the…
FastSTMF: Efficient tropical matrix factorization algorithm for sparse data
Amra Omanović, Polona Oblak, Tomaž Curk
Matrix factorization, one of the most popular methods in machine learning, has recently benefited from introducing non-linearity in prediction tasks using tropical semiring. The no…
