Improved Convergence Bounds For Operator Splitting Algorithms With Rare Extreme Errors
Anis Hamadouche, Andrew M. Wallace, Joao F. C. Mota
In this paper, we improve upon our previous work[24,22] and establish convergence bounds on the objective function values of approximate proximal-gradient descent (AxPGD), approxim…

A Low-Power Hardware-Friendly Optimisation Algorithm With Absolute Numerical Stability and Convergence Guarantees
Anis Hamadouche, Yun Wu, Andrew M. Wallace +1
We propose Dual-Feedback Generalized Proximal Gradient Descent (DFGPGD) as a new, hardware-friendly, operator splitting algorithm. We then establish convergence guarantees under ap…
