Estimating rank-one matrices with mismatched prior and noise: universality and large deviations
Alice Guionnet, Justin Ko, Florent Krzakala +1
We prove a universality result that reduces the free energy of rank-one matrix estimation problems in the setting of mismatched prior and noise to the computation of the free energ…
TAP variational principle for the constrained overlap multiple spherical Sherrington-Kirkpatrick model
David Belius, Leon Fröber, Justin Ko
Spin glass models involving multiple replicas with constrained overlaps have been studied in [FPV92; PT07; Pan18a]. For the spherical versions of these models [Ko19; Ko20] showed t…
Optimal Algorithms for the Inhomogeneous Spiked Wigner Model
Aleksandr Pak, Justin Ko, Florent Krzakala
In this paper, we study a spiked Wigner problem with an inhomogeneous noise profile. Our aim in this problem is to recover the signal passed through an inhomogeneous low-rank matri…
