MSE-based Sampling of Bandlimited Product Graph Signals via Joint Low-pass Impulse Responses

Matrix graph signals, which are associated with two factor graphs, are ubiquitous in daily life, such as time-varying physical signals in sensor networks and rating matrices in recommendation systems. In practice, due to the row-wise and column-wise smoothness, they are modeled as bandlimited (BL) g…
