Implementation and analysis of RVM method in comparison to standard SVM for solving regression and classification problems
This repository includes the implementation of SVM and RVM for both regression and classification.
Regarding the SVM both the conventional ε-SVM and v-SVM have been implemented.
For the RVM, to learn the hyperparameters we have implemented an EM update rule and the direct differentiation rule as it is described by Tipping's patent in [1]. We also implemented the sparse bayesian learning learning algorithm based on [2].
