What is the default category size threshold in the global settings for machine learning models?

Answer:

The default category size threshold is 0.05, meaning that if a category comprises 5% or less of the total group, One AI will merge it into an “other” group with the other categories that comprised 5% or less of the total group.

For example, if 1% or your total group’s home state is Arkansas and 2% of your total group’s home state is Mississippi, assuming you have made no overrides, One AI will group Mississippi and Arkansas together into an “Other" home_state bin.

The category size threshold value can be changed by inserting a decimal number ranging from 0-1 in the designated field from the augmentation page in the Global section of the One AI configuration (One AI > Edit > One AI Configuration > Global > Category Size Threshold > Override).
