Spectral Phase Transitions in Non-Linear Wigner Spiked Models
Alice Guionnet, Justin Ko, Florent Krzakala +2
We study the asymptotic behavior of the spectrum of a random matrix where a non-linearity is applied entry-wise to a Wigner matrix perturbed by a rank-one spike with independent an…
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…
Skin Cancer Detection and Tracking using Data Synthesis and Deep Learning
Yunzhu Li, Andre Esteva, Brett Kuprel +3
Dense object detection and temporal tracking are needed across applications domains ranging from people-tracking to analysis of satellite imagery over time. The detection and track…
