Alternating minimization and alternating descent over nonconvex sets
Wooseok Ha, Rina Foygel Barber
We analyze the performance of alternating minimization for loss functions optimized over two variables, where each variable may be restricted to lie in some potentially nonconvex c…

Gradient descent with nonconvex constraints: local concavity determines convergence
Rina Foygel Barber, Wooseok Ha
Many problems in high-dimensional statistics and optimization involve minimization over nonconvex constraints-for instance, a rank constraint for a matrix estimation problem-but li…
