Amazon Personalize Samples

Notebooks and examples on how to onboard and use various features of Amazon Personalize

Getting Started with the Amazon Personalize

The getting_started/ folder contains a CloudFormation template that will deploy all the resources you need to build your first campaign with Amazon Personalize.

The notebooks provided can also serve as a template to building your own models with your own data. This repository is cloned into the environment so you can explore the more advanced notebooks with this approach as well.

Amazon Personalize Use Cases examples

The core_use_cases/ folder contains detailed examples of the following typical use cases.

• Collaborative filtering based on user-item interaction tables. The intuition behind is that similar users like similar items.
  • Offline evaluation with 'hrnn' user-based recommendation.
  • Example of 'sims' item-based recommendation.
  • How recommendation changes after 'put_events'.
• Hybrid recommendation also considering user, item, and event meta-data. The result is to extrapolate to out-of-sample users and items, based on their meta-data features.
  • How to use user, item, and event 'meta-data'.
  • Exploring 'cold-start' or 'future' items.
