As u mentioned in this lesson we are doing KFold Cross-Validation, as data contain train & test set and I want to find r2_score but I am confused how will get y_test
i don’t see any variable y_test in the lecture. maybe you’re referring to accuracy_score:
from sklearn.metrics import accuracy_score accuracy_score(train_targets, train_preds)
in the lecture the train_preds variable is test_preds
Hoe can we find r2_score
r2_score(y_true, y_pred), i guess y_preds here is also test_preds
it says on documentation best possible score is 1.0 but can be negative.
it returns a float value.
