evalml.automl.make_data_splitter(X, y, problem_type, problem_configuration=None, n_splits=3, shuffle=True, random_seed=0)[source]

Given the training data and ML problem parameters, compute a data splitting method to use during AutoML search.

  • X (ww.DataTable, pd.DataFrame) – The input training data of shape [n_samples, n_features].

  • y (ww.DataColumn, pd.Series) – The target training data of length [n_samples].

  • problem_type (ProblemType) – The type of machine learning problem.

  • problem_configuration (dict, None) – Additional parameters needed to configure the search. For example, in time series problems, values should be passed in for the gap and max_delay variables. Defaults to None.

  • n_splits (int, None) – The number of CV splits, if applicable. Defaults to 3.

  • shuffle (bool) – Whether or not to shuffle the data before splitting, if applicable. Defaults to True.

  • random_seed (int) – Seed for the random number generator. Defaults to 0.
