High Cardinality Alert
Indicates that a variable contains more than 100 unique values.
Note Einstein Discovery stories are now models. We wish we could snap our fingers to update
the name everywhere, but you can expect to see the previous name in a few places until we
replace it.
Actions to Consider
To address high cardinality variables, you have the following options:
- Let Einstein Discovery ignore unique values above 100 and group them into a reserve category.
- Add one high cardinality variable, with a maximum of 200 unique values, to a model. Enable Allow high cardinality for {field name}.
- Combine field values to minimize unique values. Other high cardinality variables are limited to 100 unique values. Enable Combine remaining values into Other (Recommended).
- Limit the number of unique values by clicking the variable’s Settings tab and deselecting the values to exclude.
- For text variables, use fuzzy matching to consolidate categories with slightly different spelling variations. To learn more, see Apply Fuzzy Matching for Smarter Categorizations.
Detection Methodology
Einstein Discovery automatically alerts you when it detects a variable that contains more than 100 unique values.
