WebHow to split. There is no universally accepted rule for deciding what proportions of data should be allocated to the three samples (train, validation, test). The general criterion is to have enough data in the validation and test samples to reliably estimate the risk of the predictive models. Some popular choices are: 60-20-20, 70-15-15, 80-10-10. WebThere is a great answer to this question over on SO that uses numpy and pandas. The command (see the answer for the discussion): train, validate, test = np.split (df.sample (frac=1), [int (.6*len (df)), int (.8*len (df))]) produces a 60%, 20%, 20% split for training, validation and test sets.
