Multiple Choice

Which of the following statements a) , b) or c) is false?

A) The following code uses function xe "sklearn.model_selection module:cross_val_score function"xe "cross_val_score function sklearn.model_selection"cross_val_score to train and test a model: from sklearn.model_selection import cross_val_score
Scores = cross_val_score(estimator=knn, X=digits.data,
Y=digits.target, cv=kfold)
B) The keyword arguments in Part (a) are: $\bullet$ estimator=knn, which specifies the estimator you'd like to validate.
$\bullet$ X=digits.data, which specifies the samples to use for training and testing.
$\bullet$ y=digits.target, which specifies the targets for the samples.
$\bullet$ cv=kfold, which specifies the cross-validation generator that defines how to split the samples and targets for training and testing.
C) Function cross_val_score returns a single overall accuracy score for the model.
D) All of the above statements are true.
