XGBClassifier.evals_result() Dict[str, Dict[str, List[float]]]#

Return the evaluation results.

If eval_set is passed to the fit() function, you can call evals_result() to get evaluation results for all passed eval_sets. When eval_metric is also passed to the fit() function, the evals_result will contain the eval_metrics passed to the fit() function.

The returned evaluation result is a dictionary:

{'validation_0': {'logloss': ['0.604835', '0.531479']},
 'validation_1': {'logloss': ['0.41965', '0.17686']}}
Return type
