Use the Adaptive Decision Manager (ADM) service is to predict customer behavior. The ADM service creates predictive models and updates them by using self-learning as new responses come in. You enable the ADM service by adding one or more Pega Platform nodes. When configured for the ADM service, each node becomes a worker node that processes model updates.
Note: You need at least one decision data store node to run the ADM service. If you add an ADM node and no nodes are on the Decision Data Store tab of the Services landing page, a node is automatically added on that tab to support running the ADM service.
You can capture the ADM historical data for reporting purposes by using the ADM Data mart. The ADM Data mart is populated by periodically triggering the ADMSnapshot agent that runs the activity (pzGetAllModelDetails) that captures the state of models, predictors, and predictor binning. This activity writes that information to a table using the Data-Decision-ADM-ModelSnapshot and Data-Decision-ADM-PredictiveBinningSnapshot classes.
Note: The first time a snapshot is taken, the ADM Data mart checks for models that were created prior to Pega 7.2 and migrates them to the current version. After a successful migration, the admmart/modelIdMigrationNeeded dynamic system setting is created and the value is set to false. You do not need to repeat the migration process for successfully migrated instances. If you want ADM to trigger this step for models that were not migrated yet, change the dynamic system setting to true.
In the Models section, enter the frequency for updating adaptive models and the threshold for triggering the memory alert. The Pega Platform keeps a local cache of scoring models. The model update frequency is implemented by periodically triggering the system pulse to retrieve model updates. By default, model updates retrieve the scoring models that are required for running the strategy and the models that are different from those in the local cache.
Perform the following actions to configure the model update frequency:
