Now out in @NeuroImage_EiC, we find that scanner effects can impact community detection on brain networks. Luckily, there's a couple of harmonization methods that can help. Shout-outs to @HaochangS @takishinohara @DaniSBassett @sattertt @Penn_SIVE sciencedirect.com/science/ar…

Just out in Human Brain Mapping, a new harmonization method called CovBat! onlinelibrary.wiley.com/doi/… CovBat addresses batch effects in mean and covariance, which we demonstrate in neuroimaging data. Huge thanks to my advisors @HaochangS and @takishinohara at @Penn_SIVE

Mitigating site effects in covariance for machine learning in neuroimaging data

Multi-site neuroimaging studies are hindered by differences in images acquired across multiple sites, often referred to as site effects. In this work, we demonstrate that methods for removing site...
