Internally, it just calls first fit() and then transform() on the same data. WebFit to data, then transform it. Fits transformer to X and y with optional parameters fit_params and returns a transformed version of X. Parameters: X array-like of shape (n_samples, n_features) Input samples. y array-like of shape (n_samples,) or (n_samples, n_outputs), default=None.
WebUsing all the data, e.g., fit(X), can result in overly optimistic scores. Conversely, the transform method should be used on both train and test subsets as the same preprocessing should be applied to all the data. This can be achieved by using fit_transform on the train subset and transform on the test subset.
