The scripts in this repository contain the basic implementation (Matlab) for kernel dictionary learning and sparsity priors based white matter clustering approaches proposed in above paper.

Specifically: we have included implementations for

1. kernel sparse clustering (L-0 norm prior)
2. kernelized k-means
3. group sparse kernel dictionary learning (Group sparsity prior)
4. kernel dictionary learning with manifold prior (Laplacian prior)
5. Evaluation measures: Rand Index and variants + Silhouette (SI) measure
