Define Anomaly Thresholds

Define Anomaly Thresholds

With
Anomaly Detection
, standard sheets highlight anomalies that fall outside the 40% thresholds of the data in your prediction version. Building an AIML-THRESHOLD modeled sheet enables you to define the thresholds globally or for each combination of version, level, and account. Example: You can set a threshold of 20%.
The system default for thresholds is 40% for any combination of levels, versions, and accounts. The more specific thresholds you define override more general thresholds. Example: You define 20% as the upper and lower thresholds for all accounts, versions, and levels. You define a 10% threshold for the Salary account. The 10% threshold applies to all versions and levels for the Salary account, overriding the 20% defined in the previous row of the sheet.
When you add a row defining a combination of levels, versions, and accounts that has already been defined, the machine uses the latest definition, or the one closest to the bottom of the sheet. When you leave a cell blank in a row, the machine ignores the entire row.
