Flashcard Practice Databricks Certified Machine Learning Associate Multiple Choice

During failure analysis, a log-target revenue model consistently underpredicts high-revenue accounts after predictions are exponentiated. The team averaged log-scale predictions and then exponentiated the average for reporting. What should they investigate?

Choose the Best Answer

Whether inverse transformation or aggregation biases original-scale results and needs calibration. Whether exponentiation should be skipped so revenue reports can remain on the log scale. Whether the label column should be removed before evaluating residuals. Whether RMSE should be replaced by F1 because underprediction is a false negative.
