Geometric statistics with subspace structure preservation for SPD matrices
Cyrus Mostajeran, Nathaël Da Costa, Graham Van Goffrier +1
We present a geometric framework for the processing of SPD-valued data that preserves subspace structures and is based on the efficient computation of extreme generalized eigenvalu…
The Gaussian kernel on the circle and spaces that admit isometric embeddings of the circle
Nathaël Da Costa, Cyrus Mostajeran, Juan-Pablo Ortega
On Euclidean spaces, the Gaussian kernel is one of the most widely used kernels in applications. It has also been used on non-Euclidean spaces, where it is known that there may be…
Affine-Invariant Midrange Statistics
Cyrus Mostajeran, Christian Grussler, Rodolphe Sepulchre
We formulate and discuss the affine-invariant matrix midrange problem on the cone of positive definite Hermitian matrices , which is based on the Thompso…
