Representative Selection with Structured Sparsity

作者:

Highlights:

• We propose a novel formulation to find representatives in data samples via learning with structured sparsity.

• The proposed structured sparsity learning encourages sparsity, diversity and locality-sensitivity in representative selection.

• An accelerated proximal gradient algorithm is given to optimize the proposed formulation.
