Group-Sparse Matrix Factorization for Transfer Learning of Word Embeddings
Kan Xu, Xuanyi Zhao, Hamsa Bastani +1
Unstructured text provides decision-makers with a rich data source in many domains, ranging from product reviews in retail to nursing notes in healthcare. To leverage this informat…
A Test for Differential Ascertainment in Case-Control Studies with Application to Child Maltreatment
Matteo Sordello, Dylan S. Small
We propose a method to test for the presence of differential ascertainment in case-control studies, when data are collected by multiple sources. We show that, when differential asc…
Distributed linear regression by averaging
Edgar Dobriban, Yue Sheng
Distributed statistical learning problems arise commonly when dealing with large datasets. In this setup, datasets are partitioned over machines, which compute locally, and communi…
Capacity lower bound for the Ising perceptron
Jian Ding, Nike Sun
We consider the Ising perceptron with gaussian disorder, which is equivalent to the discrete cube intersected by random half-spaces. The perceptron's capacity is…
Multiply Robust Causal Inference with Double Negative Control Adjustment for Categorical Unmeasured Confounding
Xu Shi, Wang Miao, Jennifer C. Nelson +1
Unmeasured confounding is a threat to causal inference in observational studies. In recent years, use of negative controls to mitigate unmeasured confounding has gained increasing…
A Data-Driven Statistical Model for Predicting the Critical Temperature of a Superconductor
Kam Hamidieh
We estimate a statistical model to predict the superconducting critical temperature based on the features extracted from the superconductor's chemical formula. The statistical mode…
