Schematic illustration of the deep learning based AD prognosis. (A) A general flowchart for training and validating the prognostic model. (B) Deep network architecture for data-driven hippocampus-based AD diagnosis. (C) residual block. L: left hippocampus; R: right hippocampus. (NC: cognitively normal control; AD: Alzheimer’s disease; MCI: mild cognitive impairment; Conv: convolutional layer; BN: batch normalization; ReLU: rectified linear unit; ResBlock: residual block; Concat: concatenation layer; FC: fully connected layer).
