Memory AMP: Overflow Avoidance, Complexity Reduction, and Comparative Analysis
A general gradient-based formulation for designing MAMP algorithms is developed and it is shown that the computation of the orthogonalization parameters in this formulation can suffer from catastrophic cancellation, which explains the finite-precision instability of WS-CG-VAMP.
