Ticket #2699, comment 10
v2 v3 3 3 * There should be an option to scale the input variables (scaling should be active by default) (DONE) 4 4 * RBF regression does not support noise. If there are duplicate x vectors, model building fails. An option would be to add a diagonal matrix to the gram matrix (leading to kernel ridge regression?) (DONE) 5 * I have not found a source for the calculation of variance and LOO error 5 * I have not found a source for the calculation of variance and LOO error (DONE, removed LOO calculation) 6 6 * Don't know how to best unify covariance functions and kernel functions (there is some duplication) (DONE). 7 7 * The calculation of the covariance matrix takes a lot of time (10x longer than the equivalent calculation when using an equivalent covariance matrix). I suspect that the reason is the rather general implementation for distance calculation. (DONE)
