Biconvex Biclustering
Sam Rosen, Eric C. Chi, Jason Xu
This article proposes a biconvex modification to convex biclustering in order to improve its performance in high-dimensional settings. In contrast to heuristics that discard a subs…

Anderson Accelerated Operator Splitting Methods for Convex-nonconvex Regularized Problems
Qiang Heng, Xiaoqian Liu, Eric C. Chi
Convex-nonconvex (CNC) regularization is a novel paradigm that employs a nonconvex penalty function while maintaining the convexity of the entire objective function. It has been su…

Making Tensor Factorizations Robust to Non-Gaussian Noise
Eric C. Chi, Tamara G. Kolda
Tensors are multi-way arrays, and the Candecomp/Parafac (CP) tensor factorization has found application in many different domains. The CP model is typically fit using a least squar…
