Nonnegative Tensor Completion via Integer Optimization
Caleb Bugg, Chen Chen, Anil Aswani
Unlike matrix completion, tensor completion does not have an algorithm that is known to achieve the information-theoretic sample complexity rate. This paper develops a new algorith…
Stochastic Adaptive Line Search for Differentially Private Optimization
Chen Chen, Jaewoo Lee
The performance of private gradient-based optimization algorithms is highly dependent on the choice of step size (or learning rate) which often requires non-trivial amount of tunin…
Renyi Differentially Private ADMM for Non-Smooth Regularized Optimization
Chen Chen, Jaewoo Lee
In this paper we consider the problem of minimizing composite objective functions consisting of a convex differentiable loss function plus a non-smooth regularization term, such as…
Outer-Product-Free Sets for Polynomial Optimization and Oracle-Based Cuts
Daniel Bienstock, Chen Chen, Gonzalo Muñoz
This paper introduces cutting planes that involve minimal structural assumptions, enabling the generation of strong polyhedral relaxations for a broad class of problems. We conside…
