Heterogeneous Image-based Classification Using Distributional Data Analysis

no code implementations11 Mar 2024 Alec Reinhardt, Newsha Nikzad, Raven J. Hollis, Galia Jacobson, Millicent A. Roach, Mohamed Badawy, Peter Chul Park, Laura Beretta, Prasun K Jalal, David T. Fuentes, Eugene J. Koay, Suprateek Kundu

Our analysis reveals that when coupled with global structural radiomics features derived from the corresponding T1-MRI scans, the proposed smoothed quantile distributions derived from EPM images showed considerable improvements in sensitivity and comparable specificity in contrast to classification based on routinely used summary measures that do not account for image heterogeneity.

Bayesian longitudinal tensor response regression for modeling neuroplasticity

no code implementations12 Sep 2023 Suprateek Kundu, Alec Reinhardt, Serena Song, Joo Han, M. Lawson Meadows, Bruce Crosson, Venkatagiri Krishnamurthy

Subsequently, we apply the approach to a longitudinal Aphasia dataset consisting of task functional MRI images from a group of subjects who were administered either a control intervention or intention treatment at baseline and were followed up over subsequent visits.

Accounting for Temporal Variability in Functional Magnetic Resonance Imaging Improves Prediction of Intelligence

1 code implementation11 Nov 2022 Yang Li, Xin Ma, Raj Sunderraman, Shihao Ji, Suprateek Kundu

We compare the prediction performance for different intelligence measures based on static FC, dynamic FC, and region level time series acquired from the Adolescent Brain Cognitive Development (ABCD) study involving close to 7000 individuals.

High-dimensional Measurement Error Models for Lipschitz Loss

no code implementations26 Oct 2022 Xin Ma, Suprateek Kundu

Our estimator is designed to minimize the $L_1$ norm among all estimators belonging to suitable feasible sets, without requiring any knowledge of the noise distribution.

Elastic Shape Analysis of Brain Structures for Predictive Modeling of PTSD

1 code implementation24 May 2021 Yuexuan Wu, Suprateek Kundu, Jennifer S. Stevens, Negar Fani, Anuj Srivastava

Predictive modeling with such interactions is of paramount interest in heterogeneous mental disorders such as PTSD, where trauma exposure interacts with brain shape changes to influence behavior.

Integrative Learning for Population of Dynamic Networks with Covariates

no code implementations14 Jan 2021 Suprateek Kundu, Jin Ming, Joe Nocera, Keith M. McGregor

Although there is a rapidly growing literature on dynamic connectivity methods, the primary focus has been on separate network estimation for each individual, which fails to leverage common patterns of information.
