A DataBrew recipe removes rows with blank fields, but model recall drops because rare valid cases often have blanks. What should the team do?

Choose the Best Answer

Impute blanks across every column with the most common value before checking label impact. Review profiling results and adjust the recipe to preserve meaningful rare cases. Leave the recipe unchanged and retune the model threshold to hide the data loss. Keep dropping blank rows because a cleaner-looking table is more important than minority cases.
