[scikit-learn] modifying CV score

[Jonathan Taylor]

(Think this is right reply to from a digest... If not, apologies)

Thanks for the pointers. From what I read on the API, I gather that for an
estimator with a score method, inside GridSearchCV there will be
pseudo-code like

    ...
    estimator.fit(X_train, y_train)
    scorer = estimator.score
    return scorer(X_test, y_test)


For custom scores that are not methods of an estimator, I guess the
`make_scorer` function returns a callable with the same signature as a
score method of an estimator?
