Dynamic Bayesian network modeling for longitudinal brain morphometry

Rong Chen, Susan M. Resnick, Christos Davatzikos, Edward H. Herskovits
2012 NeuroImage  
We further applied dynamic Bayesian network modeling to a longitudinal study of normal aging and mild cognitive impairment -the Baltimore Longitudinal Study of Aging.  ...  The major advantage of dynamic Bayesian network modeling is that it can represent complicated interactions among temporal processes.  ...  In subsequent sections, we describe our DBN-based approach to modeling inter-regional associations in a longitudinal study of brain morphometry.  ...
