The incorrect or incomplete configuration of the Adaptive Decision Manager (ADM) service causes many of the problems and technical issues related to adaptive models. Use the following general guidelines to investigate and solve the most common problems.

The list of active predictors in the Active predictors overview report is empty.

When you click Show last responses on the Model Management landing page, the number of updated models is zero.

Adaptive models that are displayed in the adaptive models reports have low performance.

You want to inspect adaptive models in the adaptive model reports that are available in Prediction Studio, but no models are displayed.

You want to view the adaptive models that were generated by your strategy, but no adaptive models are shown on the Model Management landing page.

You want to inspect predictors in the Active predictors overview and Inactive predictors overview reports, but the reports are empty.

Before the introduction of model execution results, models were updated with responses even on a subset of context keys.

Adding the Adaptive Decision Manager (ADM) node is part of configuring Decisioning services. If the node fails to join the Pega Platform nodes, you cannot use the adaptive model functionality.

There is a problem with the Adaptive Decision Manager (ADM) data mart agent that captures information about the state of models, predictors, and predictor binning.

Beginning with Pega Platform version 8.4, Prediction Studio informs you when an adaptive model has an unrealistically high predictive performance score, and as a result, might be overoptimistic.

Beginning with Pega Platform version 8.4, Prediction Studio sends a notification when an adaptive model instance does not have any active predictors.

Beginning with Pega Platform version 8.4, Prediction Studio sends a notification when an adaptive model instance has access to only one active predictor.

You clicked Show last responses on the Model Management landing page and noticed that some values of the parameterized predictors are not set.

The strategy that you use to set responses to adaptive models cannot access the values of the predictors.
