Some methods for heterogeneous treatment effect estimation in high-dimensions
Scott Powers, Junyang Qian, Kenneth Jung +4
When devising a course of treatment for a patient, doctors often have little quantitative evidence on which to base their decisions, beyond their medical education and published cl…
On the diffusion approximation of nonconvex stochastic gradient descent
Wenqing Hu, Chris Junchi Li, Lei Li +1
We study the Stochastic Gradient Descent (SGD) method in nonconvex optimization problems from the point of view of approximating diffusion processes. We prove rigorously that the d…
Communication-Efficient False Discovery Rate Control via Knockoff Aggregation
Weijie Su, Junyang Qian, Linxi Liu
The false discovery rate (FDR)---the expected fraction of spurious discoveries among all the discoveries---provides a popular statistical assessment of the reproducibility of scien…
On pattern recovery of the fused Lasso
Junyang Qian, Jinzhu Jia
We study the property of the Fused Lasso Signal Approximator (FLSA) for estimating a blocky signal sequence with additive noise. We transform the FLSA to an ordinary Lasso problem.…
