| Universality of Approximate Message Passing on Semi-random Matrices | Deep Learning Theory Workshop and Summer School 2022 | 2022-08-01 |
Claim: AMP iterates on semi‑random matrices M = S Ψ S (diagonal ±1 signing with deterministic Ψ that is delocalized and ΨΨᵀ ≈ σ²I entrywise) produce the same… | ||
| The Overlap Gap Property in Principal Submatrix Recovery | Computational Phase Transitions (Simons Institute, 2020) | 2020-09-21 |
Model: n×n Gaussian matrix with an nρ×nρ planted submatrix of mean λ/n. Information-theoretic boundary shows approximate recovery threshold at λ about 2√(1/ρ ·… | ||
