Dealing with zero-inflated data: achieving SOTA with a two-fold machine learning approach

Autor: Rožanec, Jože M., Petelin, Gašper, Costa, João, Bertalanič, Blaž, Cerar, Gregor, Guček, Marko, Papa, Gregor, Mladenić, Dunja

In many cases, a machine learning model must learn to correctly predict a few data points with particular values of interest in a broader range of data where many target values are zero. Zero-inflated data can be found in diverse scenarios, such as l

Four algorithms to solve symmetric multi-type non-negative matrix tri-factorization problem

Autor: Hribar, Rok, Hrga, Timotej, Papa, Gregor, Petelin, Gašper, Povh, Janez, Pržulj, Nataša, Vukašinović, Vida

In this paper, we consider the symmetric multi-type non-negative matrix tri-factorization problem (SNMTF), which attempts to factorize several symmetric non-negative matrices simultaneously. This can be considered as a generalization of the classical
