Sparse shared structure based multi-task learning for MRI based cognitive performance prediction of Alzheimer’s disease

•A mixed sparse shared structure based multi-task learning is proposed.•The formulation can be applied on regression, classification or clustering.•An efficient optimization algorithm is derived to solve the nonsmooth formulation.•Experimental results demonstrate significant performance improvements...
