Constrained Weighted Bayesian Bootstrap
Sam Rosen, Jason Xu
We prove the weighted Bayesian bootstrap, a method for approximate sampling of a posterior distribution, can be extended to sample from general constrained posterior distributions…
Affinity Graph Connectivity in Convex Clustering
Sam Rosen, Jason Xu
We generalize finite-sample bounds for convex clustering to the setting where affinity weights appearing in the objective correspond to a general connected graph. These bounds and…
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…
OKRidge: Scalable Optimal k-Sparse Ridge Regression
Jiachang Liu, Sam Rosen, Chudi Zhong +1
We consider an important problem in scientific discovery, namely identifying sparse governing equations for nonlinear dynamical systems. This involves solving sparse ridge regressi…
