One-class classification using ℓp-norm multiple kernel fisher null approach

SR Arashloo - IEEE Transactions on Image Processing, 2023 - ieeexplore.ieee.org
We address the one-class classification (OCC) problem and advocate a one-class MKL
(multiple kernel learning) approach for this purpose. To this aim, based on the Fisher null …
