Build Your Own Recommender System Workshop - What You Need To Know

Recommender System Workshops - What You Need To Know

Start building your first recommender application with AI Blueprints in this hands-on workshop. We’ll introduce AI Blueprints, and we’ll take a look at the Flows feature in on which Blueprints is built. When you leave this workshop, you’ll have built a system that can make simple recommendations without ever having to train a model.


  • Familiarity with Python and REST APIs
  • Optional: We will provide the necessary datasets, or you can bring your own. Your data should follow these requirements and structure below.

Data Requirements

Recommendation engines learn from previous interactions between users and items. It can include rating of the item, reflecting the level of satisfaction from the item or just the interaction that means that the user purchased/clicked/viewed the item.

For example:

User Id: 22345 viewed Item Id: 3454


User Id: 22332 gave Item id: 3342 Score: 4

If you want the recommendation engine to give recommendations based on your items, you should bring to the workshop a csv file containing either: user-item interactions, or user-item-rating records.

Here is the exact format:

  1. Header row

user_id, item_id


user_id, item_id, rating

  1. Interactions (user_id, item_id) pairs, or (user_id, item_id, rating) triplets. Each interaction in a separate row.

user_id, item_id can be alpha-numeric. Rating should be numeric between 0-5.

For example:

user_id, item_id

23233, 3431

23233, 4332

23233, 4543


21111, 3431


user_id, item_id, rating

23233, 3431,4

23233, 4332, 2

23233, 4543, 1

21111,114, 0

21111, 3431, 2

A few notes:

Explicit dataset (includes rating) will bring better results in terms of accuracy
