Multi-kernel sparse subspace clustering on the Riemannian manifold of symmetric positive definite matrices
S Hechmi, A Gallas, E Zagrouba - Pattern Recognition Letters, 2019 - Elsevier
Recently, clustering in the Riemannian manifolds has received a great interest. The main
specificity of this kind of spaces is their ability to detect nonlinear forms in the real world data …
