Average-Case Integrality Gap for Non-Negative Principal Component Analysis
(2020)arXivMontanari and Richard (2015) asked whether a natural semidefinite programming (SDP) relaxation can effectively optimize x⊤Wx over ‖x‖=1 with xi≥0 for all coordinates i, where W∈ℝn×n is drawn from the Gaussian orthogonal ensemble (GOE) or a spiked matrix model. In small numerical experiments, this SDP appears to be tight for the GOE, producing a rank-one optimal matrix solution aligned with the optimal vector x. We prove, however, that as ...Working Paper -
Adaptive Extreme Edge Computing for Wearable Devices
(2020)arXivWearable devices are a fast-growing technology with impact on personal healthcare for both society and economy. Due to the widespread of sensors in pervasive and distributed networks, power consumption, processing speed, and system adaptation are vital in future smart wearable devices. The visioning and forecasting of how to bring computation to the edge in smart sensors have already begun, with an aspiration to provide adaptive extreme ...Working Paper -
