T-Phenotype: Discovering Phenotypes of Predictive Temporal Patterns in Disease Progression

2 code implementations24 Feb 2023 Yuchao Qin, Mihaela van der Schaar, Changhee Lee

Clustering time-series data in healthcare is crucial for clinical phenotyping to understand patients' disease progression patterns and to design treatment guidelines tailored to homogeneous patient subgroups.

A Variational Information Bottleneck Approach to Multi-Omics Data Integration

1 code implementation5 Feb 2021 Changhee Lee, Mihaela van der Schaar

Due to non-uniformity and technical limitations in omics platforms, such integrative analyses on multiple omics, which we refer to as views, involve learning from incomplete observations with various view-missing patterns.

Non-slice 3-stranded pretzel knots

no code implementations4 Jan 2021 Min Hoon Kim, Changhee Lee, Minkyoung Song

Greene-Jabuka and Lecuona confirmed the slice-ribbon conjecture for 3-stranded pretzel knots except for an infinite family $P(a,-a-2,-\frac{(a+1)^2}{2})$ where $a$ is an odd integer greater than $1$.

Temporal Phenotyping using Deep Predictive Clustering of Disease Progression

1 code implementation ICML 2020 Changhee Lee, Mihaela van der Schaar

In this paper, we develop a deep learning approach for clustering time-series data, where each cluster comprises patients who share similar future outcomes of interest (e. g., adverse events, the onset of comorbidities).

Actor-Critic Approach for Temporal Predictive Clustering

no code implementations25 Sep 2019 Changhee Lee, Mihaela van der Schaar

In this paper, we develop a deep learning approach for clustering time-series data, where each cluster comprises patients who share similar future outcomes of interest (e. g., adverse events, the onset of comorbidities, etc.).

A Deep Learning Approach for Dynamic Survival Analysis with Competing Risks

no code implementations ICLR 2019 Changhee Lee, Mihaela van der Schaar

Currently available survival analysis methods are limited in their ability to deal with complex, heterogeneous, and longitudinal data such as that available in primary care records, or in their ability to deal with multiple competing risks.

Estimation of Individual Treatment Effect in Latent Confounder Models via Adversarial Learning

no code implementations21 Nov 2018 Changhee Lee, Nicholas Mastronarde, Mihaela van der Schaar

Estimating the individual treatment effect (ITE) from observational data is essential in medicine.
