On solving symmetric multi-type orthogonal non-negative matrix tri-factorization problem
Rok Hribar, Gregor Papa, Janez Povh +1
We study the symmetric multi-type orthogonal non-negative matrix tri-factorization problem, where several symmetric non-negative matrices are simultaneously approximated by factors…

Four algorithms to solve symmetric multi-type non-negative matrix tri-factorization problem
Rok Hribar, Timotej Hrga, Gregor Papa +4
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 simul…
