Webb11 maj 2024 · As we can see, the grid of hyperparameter values is defined as an array of type ParamMap from an instance of the ParamGridBuilder class. Thus in order to remain … Webb19 nov. 2024 · Under this procedure, hyperparameter search does not have an opportunity to overfit the dataset as it is only exposed to a subset of the dataset provided by the outer cross-validation procedure. This reduces, if not eliminates, the risk of the search procedure overfitting the original dataset and should provide a less biased estimate of a tuned …
