How Can We Help?

Predict Homeownership with Classification

In this use case example, we will be walking through how to predict an attribute of a user using a type of Machine Learning Pipeline called Classification. Specifically, we’ll cover how to predict each user’s probability, on a scale from 0-100%, of being a homeowner, based on a list of users who are currently known to be homeowners or known to not be homeowners.

What data do I need for this prediction?

Predictions from a Classification pipeline answer the question: how likely is each user to belong to a certain group based on a list of positive labels and another list of negative labels? These labels indicate a True or False value representing if the User ID exhibits the trait we are predicting; in this case True if they are a homeowner during a specific period and False if they are not. Cortex will then analyze the behaviors of these specific groups, and use that information to predict the homeowner likelihood for every other user.

While the list of User IDs and Labels is the only information required when setting up our Classification pipeline, additional information about these users is needed in order to make accurate predictions. This information is used to build features for our pipeline:

  • User Behaviors (e.g. purchases, logins, clicks, pageviews, adds to cart, etc.) with additional metadata (e.g. What device is the user on? Where was the user referred from? etc.)
  • User Attributes (e.g. demographics, loyalty status, etc.)

How do I predict the Likelihood each User is a Homeowner?

Step 1​: Choose Pipeline Type

Select ‘Create New Pipeline’ from your Cortex account, and choose the Classification pipeline type.

Step 2: Upload Sets

This is where we upload our list of User IDs representing known homeowners and non-homeowners. This file should be a .csv or or .csv.gz file, consisting of two columns: user_id and value. The value of 1 will represent positive labels of homeowners, and the value of 0 will represent negative labels, or in this case non-homeowners.

id label
abc123 1
xyz987 0

Step 3: Define Dates

Traits can change over time, and in our example homeowners could switch to being non-homeowners. Therefore it is important to specify the date range in which it was known that these users were homeowners, otherwise these users’ homeowner status may have been different during the training window and thus would lead to less accurate predictions.

In this example we are choosing the default range, but this can be any date range in which the homeowner status of the User IDs was known.

Step 4: Specify Settings

In this step, we will name our Pipeline ‘Homeowner Classification Prediction’, have it rerun weekly on Sundays, and tag the pipeline with the ‘Homeowners’ tag. Setting a weekly schedule means that your pipeline will use the latest available data to re-generate up-to-date predictions on a weekly basis.

Step 5: Review

The final step is to review your pipeline and ensure all settings look accurate! If anything needs updated, simply go ‘Back’ in the workflow and update any step. Otherwise, click ‘Start Training’ and sit back while Cortex generates the predictions.

Step 6: Update Labels Over Time (Optional)

If you’re collecting new User IDs of known homeowners and non-homeowners over time, you can import these ​extra labels into Cortex so that your pipelines are always learning from the most recent information. To upload new labels, hit the “Edit” button on your pipeline (next to “Export Predictions”).
