Abstract: Machine learning algorithms create models from training data for the purpose of estimation, prediction and classification. While releasing parametric machine learning models requires the release of the parameters of the model, releasing non-parametric machine learning models requires the release of the training dataset along with the parameters. The release of the training dataset creates a risk of breach of privacy. An alternative to the release of the training dataset is the presentation of the non-parametric model as a service. Still, the non-parametric model as a service may leak information about the training dataset. We study how to provide differential privacy guarantees for non-parametric models as a service. We show how to apply the perturbation to the model functions of histogram, kernel density estimator, kernel SVM and Gaussian process regression in order to provide (ϵ,δ) -differential privacy. We empirically evaluate the trade-off between the privacy guarantee and the error incurred for each of these non-parametric machine learning algorithms on benchmarks and real-world datasets. Our contribution is twofold. We show that functional perturbation is not only pragmatic for releasing machine learning models as a service but also yields higher effectiveness than output perturbation mechanisms for specified privacy parameters. We show a practical step to perturbate the model functions of histogram, kernel SVM, Gaussian process regression along with kernel density estimator and perform evaluation on a real-world dataset as well as a selection of benchmarks.
