On optimal tests for rotational symmetry against new classes of hyperspherical distributions
Eduardo García-Portugués, Davy Paindaveine, Thomas Verdebout
Motivated by the central role played by rotationally symmetric distributions in directional statistics, we consider the problem of testing rotational symmetry on the hypersphere. W…
Distance weighted discrimination of face images for gender classification
Mónica Benito, Eduardo García-Portugués, J. S. Marron +1
We illustrate the advantages of distance weighted discrimination for classification and feature extraction in a High Dimension Low Sample Size (HDLSS) situation. The HDLSS context…
Langevin diffusions on the torus: estimation and applications
Eduardo García-Portugués, Michael Sørensen, Kanti V. Mardia +1
We introduce stochastic models for continuous-time evolution of angles and develop their estimation. We focus on studying Langevin diffusions with stationary distributions equal to…
