Joint Latent Class Trees: A Tree-Based Approach to Modeling Time-to-event and Longitudinal Data
Ningshan Zhang, Jeffrey S. Simonoff
In this paper, we propose a semiparametric, tree based joint latent class modeling approach (JLCT) to model the joint behavior of longitudinal and time-to-event data. Existing join…

Ningshan Zhang, Kyle Schmaus, Patrick O. Perry
We consider a particular instance of a common problem in recommender systems: using a database of book reviews to inform user-targeted recommendations. In our dataset, books are ca…
Algorithms and Theory for Multiple-Source Adaptation
Judy Hoffman, Mehryar Mohri, Ningshan Zhang
This work includes a number of novel contributions for the multiple-source adaptation problem. We present new normalized solutions with strong theoretical guarantees for the cross-…
