Deconfounded Dimension Reduction via Partial Embeddings

Andrew A. Chen, Kelly A. Clark, Blake E. Dewey…·the North American Imaging in Multiple Sclerosis Cooperative

The paper introduces the PARE framework to remove confounders from dimension reduction methods, showing it can eliminate batch effects in single-cell data and separate clinical from technical variability in neuroimaging.

Inter-scanner brain MRI volumetric biases persist even in a harmonized multi-subject study of multiple sclerosis

Kelly A. Clark, Carly M. O’Donnell, Mark A. Elliott…·the NAIMS Cooperative

This study shows that brain MRI volumetric biases persist across different scanners in a harmonized MS study, with site explaining over 50% of volume variation.
