3.2 Original Formulation of the HSVM

Cho et al. [4] proposed the hyperbolic support vector machine which finds a max-margin separator where margin is defined as the hyperbolic point to line distance. We demonstrate our results in a binary classification setting. Extension to multi-class classification is straightforward using Platt-scaling [31] in the one-vs-rest scheme or majority voting in one-vs-one setting.
