DMD Prediction of MIMO Channel Using Tucker Decomposition
Irina Kopnina, Dmitry Artemasov, Sergey Matveev
Accurate channel state information (CSI) prediction is crucial for next-generation multiple-input multiple-output (MIMO) communication systems. Classical prediction methods often b…
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…
