We propose a new framework to solve the Diffusion Basis Functions model based on the alternating direction method of multipliers. We present an iterative, simple and efficient algorithm with closed-form updates. The proposal introduces a new regularization term to promote sparsity in the number of estimated fibers. Our experimental result shows that diffusion dictionary approaches benefit from our proposal.
