Flashcard Practice AWS Certified Machine Learning Engineer - Associate Multiple Choice

A company sees thousands of impossible negative transaction amounts after a new ingestion release. What should the ML engineer do before treating them as ordinary outliers?

Choose the Best Answer

Delete all negative rows because negative values are always invalid. Winsorize the values immediately and train the model. Increase the model learning rate so outliers have less influence. Check ingestion changes, source semantics, validation rules, and parsing behavior.
