Spherical Regression under Mismatch Corruption with Application to Automated Knowledge Translation
Xu Shi, Xiaoou Li, Tianxi Cai
Motivated by a series of applications in data integration, language translation, bioinformatics, and computer vision, we consider spherical regression with two sets of unit-length…
A Fast Divide-and-Conquer Sparse Cox Regression
Yan Wang, Nathan Palmer, Qian Di +3
We propose a computationally and statistically efficient divide-and-conquer (DAC) algorithm to fit sparse Cox regression to massive datasets where the sample size is exceedin…
Multi-view Banded Spectral Clustering with Application to ICD9 Clustering
Luwan Zhang, Katherine Liao, Issac Kohane +1
Despite recent development in methodology, community detection remains a challenging problem. Existing literature largely focuses on the standard setting where a network is learned…
Clinical Concept Embeddings Learned from Massive Sources of Multimodal Medical Data
Andrew L. Beam, Benjamin Kompa, Allen Schmaltz +6
Word embeddings are a popular approach to unsupervised learning of word relationships that are widely used in natural language processing. In this article, we present a new set of…
Robust and Efficient Semi-Supervised Estimation of Average Treatment Effects with Application to Electronic Health Records Data
David Cheng, Ashwin Ananthakrishnan, Tianxi Cai
We consider the problem of estimating the average treatment effect (ATE) in a semi-supervised learning setting, where a very small proportion of the entire set of observations are…
Variance Components Genetic Association Test for Zero-inflated Count Outcomes
Matthew Goodman, Lori Chibnik, Tianxi Cai
Commonly in biomedical research, studies collect data in which an outcome measure contains informative excess zeros; for example when observing the burden of neuritic plaques in br…
