Scikit-learn: Averaging Cross-Validation Scores
Beginner
The problem, from first principles
A single train/test split gives one noisy estimate of model quality. Cross-validation repeats the split, and the average over folds is the number usually reported as the model's score.
From theory to code
Implement mean_cv_score(scores), returning the average of the fold scores.
Constraints
- Returns a Python float.
Hints
Hint 1
Take the mean of the array and convert to float.
