Flashcard Practice Databricks Certified Machine Learning Associate Multiple Choice

A regression experiment logs `rmse` for each run, and lower values are better. Which query pattern best selects the best run?

Choose the Best Answer

Filter with `metrics.rmse IS NOT NULL` and rely on the default run order. Order by `params.rmse ASC` because lower error is a training parameter. Search the experiment with `order_by=['metrics.rmse DESC']` and choose the first run. Search the experiment with `order_by=['metrics.rmse ASC']` and `max_results=1`.
