Key: ADAS-cog, Alzheimer’s disease assessment scale–cognitive subscale; CDR-GLOB, clinical dementia rating–global; CDR-SOB, clinical dementia rating–sum of boxes; MMSE, Mini-Mental State Examination; oRF-L1, oblique RF with the L1 norm constraint; oRF-L1-soft, oblique RF with L1 and soft split; SVM, support vector machine; wRs, weighted Pearson’s correlation coefficients.
