DICE: Deep Significance Clustering for Outcome-Aware Stratification

no code implementations7 Jan 2021 Yufang Huang, Kelly M. Axsom, John Lee, Lakshminarayanan Subramanian, Yiye Zhang

Following the representation learning and clustering steps, we embed the objective function in DICE with a constraint which requires a statistically significant association between the outcome and cluster membership of learned representations.

Hierarchical Optimal Transport for Multimodal Distribution Alignment

2 code implementations NeurIPS 2019 John Lee, Max Dabagia, Eva L. Dyer, Christopher J. Rozell

Our results demonstrate that when clustered structure exists in datasets, and is consistent across trials or time points, a hierarchical alignment strategy that leverages such structure can provide significant improvements in cross-domain alignment.
