Using Predictive Audiences

You can create predictive audiences in the mParticle UI.

Note that you may see the name “Vidora” instead of Cortex in some documentation and UI screens.

Prerequisites

1. If you haven’t yet, set up a Cortex event output.
2. Set up a Cortex feed input.
3. Once the live integration has been configured and verified, reach out to your Customer Success Manager (CSM) in order to initiate a replay of historical data. Providing historical events enables Cortex to start building ML pipelines right away rather than waiting for a sufficient volume of data to be gathered through the live integration.

Create a predictive audience

To create and activate a predictive audience:

1. In mParticle, navigate to Audiences > Real-time and click New Audience.
2. Enter your information in the New Audience form and click Create.
3. mParticle launches the criteria builder:

4. If you haven’t already created a user prediction, click User Prediction from the list and enter the User Prediction information:

   If you’ve already created a user prediction, select it from the list in User Attributes.

5. Click Create prediction.
6. mParticle displays the audience definition, where you can see that the Cortex pipeline has been created. Specify the threshold. For example, if you wanted a likelihood of greater than 90 percent, you’d set the following values:
7. Click Done. mParticle creates both a percentile and score version for you to select.
8. Choose either Save as Draft or Activate.
9. Once you choose Activate, mparticle prompts you to optionally create an A/B test, and then connect to an output.
