(a) Conventional sparse representation of a specific temporal segment of an individual subject. (c) The proposed group-wise sparse representation of specific corresponding temporal segments across all subjects. (b): The spatial pattern of an example reconstructed functional network via mapping a specific row (highlighted by red) of αi,wj back onto the cortical surface based on conventional sparse representation. (d): The spatial pattern of an example group-wise consistent reconstructed functional network via mapping a specific row (highlighted by red) of PI,wj back onto the cortical surface based on the proposed group-wise sparse representation.
