Low-rank nonnegative tensor approximation via alternating projections and sketching

Azamat Sultonov, Sergey Matveev, Stanislav Budzinskiy

We show how to construct nonnegative low-rank approximations of nonnegative tensors in Tucker and tensor train formats. We use alternating projections between the nonnegative ortha…

Sketching for low-rank nonnegative matrix approximation: Numerical study

Sergey A. Matveev, Stanislav Budzinskiy

We propose new approximate alternating projection methods, based on randomized sketching, for the low-rank nonnegative matrix approximation problem: find a low-rank approximation o…
