logical; if TRUE (default), re-optimise hyperparameters. Set to FALSE for a fast incremental Cholesky update that keeps all hyper-parameters (and warping parameters) fixed.
optional numeric vector of per-observation noise variances
for the update points (length nrow(X_u)). Required when the model was
fitted with noise; must be omitted otherwise.
