Stanford University researchers have created an algorithm that may help detect autism from analyzing functional magnetic resonance imaging (fMRI) brain scans, and that also can forecast the severity of autism symptoms in individuals.
The explainable artificial intelligence (XAI) algorithm maps neural activity visualized in fMRI scans over time to produce "fingerprints," which can be sorted and classified based on common elements.
The algorithm applies a simple mathematical model that assesses brain regional interactions and interconnectivity, focusing on three regions exhibiting substantial interconnectivity differences in a groupable portion of the dataset; those three regions have been previously associated with autism pathology.
The researchers found the XAI algorithm evaluated brain scans from a sample of roughly 1,100 patients, extracting a group whom human clinicians had diagnosed as autistic with 82% accuracy.
