Product recommendation

In this tutorial, we'll show you how to:

Create a predictive model for product recommendation using a recommender.

Let's dive in.

You'll need a Faraday account — signup is free!

Confirm your data

Event stream

Unless you’ve already created it for another quickstart or purpose, you’ll need to add the following event stream to your account:

Transaction

What’s an event stream?

Predicting a certain customer behavior requires historical examples of customers exhibiting that behavior. Faraday works best when that data comes in the form of “events” — specific actions or occurrences that happened at specific times.

Formulating data this way helps you define cohorts more expressively.

For example, a Customers cohort could be defined as the group of people who have all experienced a Transaction event at least once.

For more, see our docs on Cohorts, Events, Traits, and Datasets (which define how events and traits emerge from your data).

API via cURL

Dashboard

To verify, use a GET /streams request. Your response should look like this:

[{
  "name": "Transaction",
  "id": "$TRANSACTION_STREAM_ID"
, ...}]

Make note of the IDs of the necessary streams.

If the required event stream isn't there, follow the instructions using this button, then return here to resume.

Create a product recommendation recommender

API via cURL

Dashboard

Use a POST /recommenders request:

curl https://api.faraday.ai/recommenders --json '{
  "name": "Product recommendation",
  "stream_name": "transaction",
  "stream_property_name": "product"
}'

Your recommender will start building in the background. You can proceed immediately with the next set of instructions. When your recommender is done building, you’ll get an email.
