Flashcard Practice Databricks Certified Machine Learning Associate Multiple Choice

A high-capacity model has low training error but unstable validation scores across folds. Why might adding more representative training data help?

Choose the Best Answer

It makes fold-level variation less relevant only when the new data comes from production. It changes the validation objective from generalization to training loss. It can reduce variance by making the fitted model less dependent on a small training sample. It lets the team choose a deeper model based on training score alone.
