Linear convergence of Gearhart-Koshy accelerated Kaczmarz methods for tensor linear systems
The Gearhart-Koshy acceleration yields linear convergence to the least-norm solution for tensor linear systems with improved rates over plain Kaczmarz across incremental, shuffle-once, and random-reshuffling schemes.
