  1. No. of groups of test sets: the sequence number the eight groups of the test sets; Number of CTL samples: the number of the CTL samples in each group of data set; Number of AD samples: the number of the AD samples in each group of data set; sum of Aβ plaque depositions in hippocampus: the total number of the Aβ plaque depositions in hippocampus in the brain histological image slices of AD; Number of matched Aβ plaque depositions: the total number of the Aβ plaque depositions which are matched by the marked pixels in brain MR images of corresponding AD samples; match rate: the ratio of the number of the matched Aβ plaque depositions to total number of the Aβ plaque depositions; Number of unmatched Aβ plaques: the total number of the Aβ plaque depositions which are not matched by the marked pixels in brain MR images of corresponding AD samples; miss rate: the ratio of the number of the unmatched Aβ plaque depositions to total number of the Aβ plaque depositions
