First-order methods for geodesically convex optimization

H Zhang, S Sra - Conference on learning theory, 2016 - proceedings.mlr.press
Geodesic convexity generalizes the notion of (vector space) convexity to nonlinear metric
spaces. But unlike convex optimization, geodesically convex (g-convex) optimization is …

Pedestrian detection via classification on riemannian manifolds

O Tuzel, F Porikli, P Meer - IEEE transactions on pattern …, 2008 - ieeexplore.ieee.org
