svr_regression

Support vector regression (SVR) using an epsilon-insensitive dual margin model with linear, polynomial, and radial basis function kernels, trained with a Pegasos-style dual subgradient descent loop. Learns from a dataset object implementing the regression_dataset_protocol protocol and returns a regressor term that can be used for prediction and exported as predicate clauses.
