From: Machine learning prediction of future amyloid beta positivity in amyloid-negative individuals
Data selection procedure for predicting progression to A\(\beta\)-positivity for a CSF-cohort and b PET-cohort. The data from Stable A+ individuals, who are A\(\beta\)-positive at baseline with their A\(\beta\) values close to the cutoff point, are employed only during the training of the model and serve as A\(\beta\)-Converters for balancing the dataset during the training. They are not used in the testing of the model
