Cross-Validation for Model Testing
7 questions found
Cross validation for model testing is the practice of training and testing a model multiple times on different data splits to get a more reliable estimate of its true performance.
Real-world example
A team uses five fold cross validation to confirm their model's accuracy is consistent rather than the result of one lucky data split.
