Discovery of Generalizable TBI Phenotypes Using Multivariate Time-Series Clustering

no code implementations15 Jan 2024 Hamid Ghaderi, Brandon Foreman, Chandan K. Reddy, Vignesh Subbian

Importantly, while certain features varied by age, the core characteristics of TBI manifestations tied to each phenotype remain consistent across diverse populations.

Identifying TBI Physiological States by Clustering Multivariate Clinical Time-Series Data

1 code implementation23 Mar 2023 Hamid Ghaderi, Brandon Foreman, Amin Nayebi, Sindhu Tipirneni, Chandan K. Reddy, Vignesh Subbian

Determining clinically relevant physiological states from multivariate time series data with missing values is essential for providing appropriate treatment for acute conditions such as Traumatic Brain Injury (TBI), respiratory failure, and heart failure.

Computable Phenotypes for Post-acute sequelae of SARS-CoV-2: A National COVID Cohort Collaborative Analysis

no code implementations22 Mar 2023 Sarah Pungitore, Toluwanimi Olorunnisola, Jarrod Mosier, Vignesh Subbian

In this study, we defined computable phenotypes (or heuristics) and meta-heuristics for PASC phenotypes based on COVID-19 severity and symptom duration.

WindowSHAP: An Efficient Framework for Explaining Time-series Classifiers based on Shapley Values

1 code implementation11 Nov 2022 Amin Nayebi, Sindhu Tipirneni, Chandan K Reddy, Brandon Foreman, Vignesh Subbian

We also show that our Dynamic WindowSHAP algorithm focuses more on the most important time steps and provides more understandable explanations.
