A computer-implemented method for identifying character traits associated with a target subject includes acquiring image data of a target subject from an image data source, rendering a 3D image data set, comparing each of a plurality of regions of interest within the 3D image set to a historical image data set to identify active regions of interest, grouping subsets of the regions of interest into one or more convolutional feature layers, wherein each convolutional feature layer probabilistically maps to a pre- identified character trait, and applying a convolutional neural network model to the convolutional feature layers to identify a pattern of active regions of interest within each convolutional feature layer to predict whether a target subject possesses the pre- identified character trait.
