accuracy_vs_inducing_points.pdf - average prediction error and training time as functions of the number of inducing points selected by two different methods with one standard deviation (using 10-fold cross validation).

accuracy_vs_time.pdf - prediction error as
function of training time for various methods discussed in the related paper.

autotuning_vs_gridsearch.pdf - average validation loss as function of the RBF kernel length-scale parameter q, computed by grid search and 10-fold cross validation. The red circle represents the hyperparameter found by our proposed automatic tuning approach.


We propose a fast inference method for Bayesian nonlinear support vector machines that leverages stochastic variational inference and inducing points. Our experiments show that the proposed method is faster than competing Bayesian approaches and scales easily to millions of data points. It provides additional features over frequentist competitors such as accurate predictive uncertainty estimates and automatic hyperparameter search.
