| Research Abstract |
We generated classifiers to predict the conversion from mild cognitive impairment to dementia by using clinical information and indices obtained from brain imaging. They predict whether it converts or not, and when converts. We contrived linear and non-linear classifiers on the basis of supervised learning methodology. Incremental diagnostic value of parameters obtained from imaging and statistical parametric mapping was clarified by comparing performances of classifiers with and without incorporating image-related inputs.
