Sketch‐and‐project methods for tensor linear systems

For tensor linear systems with respect to the popular t‐product, we first present the sketch‐and‐project method and its adaptive variants. Their Fourier domain versions are also investigated. Then, considering that the existing sketching tensor or way for sampling has some limitations, we propose tw...
