Time Series Treatment Effects Analysis with Always-Missing Controls
Juan Shu, Qiyu Han, George Chen +8
Estimating treatment effects in time series data presents a significant challenge, especially when the control group is always unobservable. For example, in analyzing the effects o…
Generalized Prompt Tuning: Adapting Frozen Univariate Time Series Foundation Models for Multivariate Healthcare Time Series
Mingzhu Liu, Angela H. Chen, George H. Chen
Time series foundation models are pre-trained on large datasets and are able to achieve state-of-the-art performance in diverse tasks. However, to date, there has been limited work…
An Introduction to Deep Survival Analysis Models for Predicting Time-to-Event Outcomes
George H. Chen
Many applications involve reasoning about time durations before a critical event happens--also called time-to-event outcomes. When will a customer cancel a subscription, a coma pat…
Fairness in Survival Analysis with Distributionally Robust Optimization
Shu Hu, George H. Chen
We propose a general approach for encouraging fairness in survival analysis models based on minimizing a worst-case error across all subpopulations that occur with at least a user-…
