Bayesian Nonlinear Support Vector Machines and Discriminative Factor Modeling

  title={Bayesian Nonlinear Support Vector Machines and Discriminative Factor Modeling},
  author={Ricardo Henao and Xin Yuan and Lawrence Carin},
A new Bayesian formulation is developed for nonlinear support vector machines (SVMs), based on a Gaussian process and with the SVM hinge loss expressed as a scaled mixture of normals. We then integrate the Bayesian SVM into a factor model, in which feature learning and nonlinear classifier design are performed jointly; almost all previous work on such discriminative feature learning has assumed a linear classifier. Inference is performed with expectation conditional maximization (ECM) and… CONTINUE READING
