Plasticity without phenomenology: a first step
Sabyasachi Chatterjee, Giacomo Po, Xiaohan Zhang +2
A novel, concurrent multiscale approach to meso/macroscale plasticity is demonstrated. It utilizes a carefully designed coupling of a partial differential equation (pde) based theo…
Isotonic regression in general dimensions
Qiyang Han, Tengyao Wang, Sabyasachi Chatterjee +1
We study the least squares regression function estimator over the class of real-valued functions on that are increasing in each coordinate. For uniformly bounded signals…
Local Minimax Complexity of Stochastic Convex Optimization
Yuancheng Zhu, Sabyasachi Chatterjee, John Duchi +1
We extend the traditional worst-case, minimax analysis of stochastic convex optimization by introducing a localized form of minimax complexity for individual functions. Our main re…
