Structured sparsity regularized multiple kernel learning for Alzheimer’s disease diagnosis

作者:

Highlights:

• For Alzheimer’s disease (AD) diagnosis, we consider the integration of multi-modality imaging and genetic data which encode different level of knowledge.

• With a focus on taking advantage of both phenotype and genotype information, a novel structured sparsity, defined by ℓ1, p -norm (p > 1), regularized multiple kernel learning method is designed.

• An efficient block coordinate descent algorithm applicable to any case with p > 1 was derived to solve the proposed formulation.
