Hello, I'm testing machine learning features using the kibana sample data.

I couldn't find detailed information about the options when creating ml jobs. I want to know what exclude frequent means, and how I could use them.

I used by field/partition field/over field to test exclude frequent option, but failed showing the error below. Can I get some examples of making ml using exclude frequent?

[request body.analysisConfig.detectors.0.exclude\_frequent]: definition for this key is missing

 ![exclude frequent](https://us1.discourse-cdn.com/elastic/original/3X/9/b/9b2e15a19d2d17957932b40828fcfa92c1ec269c.png)

Thank you!

is defined here: [Create anomaly detection jobs API | Elasticsearch Guide [8.11] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/current/ml-put-job.html)

The error you found [is a known bug](https://github.com/elastic/kibana/pull/81121) - to be fixed in v7.10

Just so you know, the introduction of [Filter lists](https://www.elastic.co/guide/en/machine-learning/7.8/ml-configuring-detector-custom-rules.html) often obviates the need for the `exclude_frequent` setting, which pre-dated Filters. With filters, you have specific control over which entities you'd like to omit from anomaly creation.
