ray.data.preprocessors.StandardScaler.fit

StandardScaler.fit(ds: Dataset) → Preprocessor

Calling it more than once will overwrite all previously fitted state: preprocessor.fit(A).fit(B) is equivalent to preprocessor.fit(B).

Parameters:

ds – Input dataset.

Returns:

The fitted Preprocessor with state attributes.

Return type:
