To enable external learning

You can use the Learning Java™ API to write your own learning module. You must configure the runtime environment to recognize your learning utility in Marketing Platform.

In Marketing Platform for the runtime environment, edit the following configuration properties in the Interact > offerserving category. The configuration properties for the learning optimizer API exist in Interact > offerserving > External Learning Config category.

Configuration property	Setting
optimizationType	ExternalLearning
externalLearningClass	class name for the external learning
externalLearningClassPath	The path to the class or jar files on the runtime server for the external learning. If you are using a server group and all the runtime servers reference the same instance of Marketing Platform, every server must have a copy of the class or jar files in the same location.

You must restart the Interact runtime server for these changes to take effect.
