Low Rank Representation on SPD matrices with Log-Euclidean metric
作者:
Highlights:
• Proposing a novel LRR model on SPD matrices space with Log-Euclidean metric, namely LogELRR. This is different from the model proposed in [15] where the LRR was implemented in the tangent space of the manifold thus it is a first order approximation to the manifold.
• Providing kernelise extensions of LogELRR method.
• Deriving an optimization problem which has a closed-form solution makes our proposed algorithms faster.
