A Unified Robust Classification Model
This provides a framework for researchers to generalize and enhance multiple classification methods simultaneously, though it is incremental as it builds on existing models.
The paper tackles the problem of unifying diverse binary classification algorithms like SVM, MPM, and FDA into a single robust optimization model, enabling cross-applicability of improvements and theoretical results across these methods.
A wide variety of machine learning algorithms such as support vector machine (SVM), minimax probability machine (MPM), and Fisher discriminant analysis (FDA), exist for binary classification. The purpose of this paper is to provide a unified classification model that includes the above models through a robust optimization approach. This unified model has several benefits. One is that the extensions and improvements intended for SVM become applicable to MPM and FDA, and vice versa. Another benefit is to provide theoretical results to above learning methods at once by dealing with the unified model. We give a statistical interpretation of the unified classification model and propose a non-convex optimization algorithm that can be applied to non-convex variants of existing learning methods.
