deephyper.analysis.hpo.parameters_at_max

deephyper.analysis.hpo.parameters_at_max(df: DataFrame, column: str = 'objective', prefix: str = 'p:', n_last: int | float = 1.0) → Tuple[dict, float]

Return the parameters at the maximum of the given column function.

Parameters:

• df (pd.DataFrame) – the results of a Hyperparameter Search.

• column (str) – the column to use for the maximization. Defaults to "objective".

• prefix (str) – the prefix of columns of parameters.

• n_last (int | float) – Select the max among the n_last rows. If it is a float it is among the int(n_last * len(df)) last rows.

Returns:

the parameters at the maximum of the column and its corresponding

value.

Return type:

Tuple[dict, float]
