Equivariant Spherical Deconvolution: Learning Sparse Orientation Distribution Functions from Spherical Data

1 code implementation17 Feb 2021 Axel Elaldi, Neel Dey, Heejong Kim, Guido Gerig

We then show improved downstream performance on fiber tractography measures on the Tractometer benchmark dataset.

Q-space Conditioned Translation Networks for Directional Synthesis of Diffusion Weighted Images from Multi-modal Structural MRI

1 code implementation24 Jun 2021 Mengwei Ren, Heejong Kim, Neel Dey, Guido Gerig

Further, such approaches can restrict downstream usage of variably sampled DWIs for usages including the estimation of microstructural indices or tractography.

Learning to Compare Longitudinal Images

1 code implementation5 Apr 2023 Heejong Kim, Mert R. Sabuncu

For example, normalizing for nuisance variation might be hard in settings where there are a lot of idiosyncratic changes.

A Framework for Interpretability in Machine Learning for Medical Imaging

no code implementations2 Oct 2023 Alan Q. Wang, Batuhan K. Karaman, Heejong Kim, Jacob Rosenthal, Rachit Saluja, Sean I. Young, Mert R. Sabuncu

To answer these questions, we identify a need to formalize the goals and elements of interpretability in MLMI.

Robust Learning via Conditional Prevalence Adjustment

1 code implementation24 Oct 2023 Minh Nguyen, Alan Q. Wang, Heejong Kim, Mert R. Sabuncu

CoPA assumes that (1) generation mechanism is stable, i. e. label Y and confounding variable(s) Z generate X, and (2) the unstable conditional prevalence in each site E fully accounts for the unstable correlations between X and Y .
