A maximum margin and minimum volume hyper-spheres machine with pinball loss for imbalanced data classification
Knowledge-Based Systems, Volume 95, Issue C, 2015.
The twin hyper-sphere support vector machine (THSVM) classifies two classes of samples via two hyper-spheres instead of a pair of nonparallel hyper-planes as in the conversional twin support vector machine (TSVM). Moreover THSVM avoids the matrix inverse operation when solving two dual quadratic programming problems (QPPs). However it can...More
