WebThat is, a shuffle split with a 20% test proportion will generate infinitely many randomly split 80/20 train/test buckets. A K=4 fold split will leave you with 5 buckets, of which you treat one as your 20% validation and iterate through 5 times to get a generalized score. WebLilio can also generate train/test splits and perform cross-validation. To do that, a splitter is called from sklearn.model_selection e.g. ShuffleSplit and used to split the resampled data: from sklearn.model_selection import ShuffleSplit splitter = ShuffleSplit(n_splits= 3) lilio.traintest.split_groups(splitter, bins)
