Reconfigurable FPGA-Based Solvers For Sparse Satellite Control
Anis Hamadouche, Yun Wu, Mathini Sellathurai +2
This paper introduces a novel reconfigurable and power-efficient FPGA (Field-Programmable Gate Array) implementation of an operator splitting algorithm for Non-Terrestial Network's…
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…
Probabilistic Verification of Approximate Algorithms with Unstructured Errors: Application to Fully Inexact Generalized ADMM
Anis Hamadouche, Yun Wu, Andrew M. Wallace +1
We analyse the convergence of an approximate, fully inexact, ADMM algorithm under additive, deterministic and probabilistic error models. We consider the generalized ADMM scheme th…
Sharper Bounds for Proximal Gradient Algorithms with Errors
Anis Hamadouche, Yun Wu, Andrew M. Wallace +1
We analyse the convergence of the proximal gradient algorithm for convex composite problems in the presence of gradient and proximal computational inaccuracies. We derive new tight…
