Figure 1.

An illustration of the proposed regression model using longitudinal data. 𝕏 is the input baseline MRI data, 𝕐 is the target tensor data, and 𝕎 is the weight model projection. For the input 𝕏, x-axis represents the features, and y-axis denotes the subjects. For the target tensor data 𝕐, x-axis represents clinical scores, y-axis represents the subjects, and z-axis denotes the time points. For the model parameters 𝕎, x-axis plots the clinical scores, y-axis represents the features, and z-axis denotes the time points. We want to establish a linear model 𝕎 between the input 𝕏 and output 𝕐.
