Deep Copula-Based Survival Analysis for Dependent Censoring with Identifiability Guarantees

AAAI 2024technical

Censoring is the central problem in survival analysis where either the time-to-event (for instance, death), or the time-to censoring (such as loss of follow-up) is observed for each sample. The majority of existing machine learning-based survival analysis methods assume that survival is conditionall…

Multi-Instance Causal Representation Learning for Instance Label Prediction and Out-of-Distribution Generalization

NeurIPS 2022accept

Multi-instance learning (MIL) deals with objects represented as bags of instances and can predict instance labels from bag-level supervision. However, significant performance gaps exist between instance-level MIL algorithms and supervised learners since the instance labels are unavailable in MIL. Mo…
