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…
