     Primary metric| Main metric used for scoring your model. [Learn more about model metrics](how-to-configure-auto-train.md#primary-metric).
-   Debug model via the Responsible AI dashboard | Generate a Responsible AI dashboard to do a holistic assessment and debugging of the recommended best model. This includes insights such as model explanations, fairness and performance explorer, data explorer, model error analysis. [Learn more about how you can generate a Responsible AI dashboard.](./how-to-responsible-ai-insights-ui.md). RAI Dashboard can only be run if 'Serverless' compute (preview) is specified in the experiment set-up step.
+   Enable ensemble stacking | Ensemble learning improves machine learning results and predictive performance by combining multiple models as opposed to using single models. [Learn more about ensemble models](concept-automated-ml.md#-ensemble-models).
     Blocked algorithm| Select algorithms you want to exclude from the training job. <br><br> Allowing algorithms is only available for [SDK experiments](how-to-configure-auto-train.md#supported-algorithms). <br> See the [supported algorithms for each task type](/python/api/azureml-automl-core/azureml.automl.core.shared.constants.supportedmodels).
     Exit criterion| When any of these criteria are met, the training job is stopped. <br> *Training job time (hours)*: How long to allow the training job to run. <br> *Metric score threshold*:  Minimum metric score for all pipelines. This ensures that if you have a defined target metric you want to reach, you don't spend more time on the training job than necessary.
     Concurrency| *Max concurrent iterations*: Maximum number of pipelines (iterations) to test in the training job. The job won't run more than the specified number of iterations.
