Table 2.

Comparison of performances of five different methods on Experiment 1. The reported values are the correlation coefficient (for MMSE and ADAS-Cog regression) and accuracy (for AD vs. HC and MCI vs. HC classification), averaged on 10-fold tests (with standard deviation also reported).

Methods	Correlation coefficient		Classification accuracy
	MMSE	ADAS-Cog	AD vs. HC	MCI vs. HC
MRI-based	0.504 ± 0.038	0.609 ± 0.014	0.848 ± 0.026	0.739 ± 0.028
PET-based	0.658 ± 0.027	0.670 ± 0.018	0.845 ± 0.035	0.797 ± 0.023
CSF-based	0.465 ± 0.019	0.474 ± 0.013	0.805 ± 0.022	0.536 ± 0.044
CONCAT	0.658 ± 0.023	0.695 ± 0.011	0.920 ± 0.033	0.800 ± 0.024
Proposed M3T	0.697 ± 0.022	0.739 ± 0.012	0.933 ± 0.022	0.832 ± 0.015

AD = Alzheimer’s Disease, HC = Healthy Control, MCI = Mild Cognitive Impairment, MMSE = Mini-Mental State Examination, ADAS-Cog = Alzheimer’s Disease Assessment Scale - Cognitive Subscale
