InVA: Integrative Variational Autoencoder for Harmonization of Multi-modal Neuroimaging Data

no code implementations5 Feb 2024 Bowen Lei, Rajarshi Guhaniyogi, Krishnendu Chandra, Aaron Scheffler, Bani Mallick

While there is a growing literature on image-on-image regression to delineate predictive inference of an image based on multiple images, existing approaches have limitations in efficiently borrowing information between multiple imaging modalities in the prediction of an image.
