Recommenders Engine Example Layout (REEL) is a cross-platform movie recommendation application that demonstrates the integration of example recommendation algorithms from Microsoft/Recommenders into an application workflow. The following sections will demonstrate how to locally build REEL. These sections will guide the reader into:
- Creating an ML model endpoint
- Setting up and populating Azure SQL Database
- Setting up Azure Search
- Running the app's backend on Azure using AKS
- Installing the Xamarin.Forms app for the mobile client
Currently, REEL runs Simple Algorithm for Recommendation (SAR) and LightGBM algorithms. The application is built using Xamarin.Forms, so it is supported on iOS, Android and Windows Desktop. The algorithms are trained on the MovieLens dataset.
At a high level, this project is composed of 3 main folders
- backend: where the Flask web service logic / deployment files are kept. This folder's README also contains instructions for setting up the backend and the database
- data: where scripts for setting up the SQL database with the movielens dataset are kept
- mobile: where the Xamarin.Forms cross platform application sits. This folder's README contains a high level tour of how the application is structured, as well as information about how to run the application
To get started running the mobile application, a few steps must be followed:
- Deploy a SAR model by running the SAR notebook
- Deploy a LightGBM model by running the LightGBM notebook
- Set up and deploy the backend to AKS
- Set up and run the Xamarin.Forms application on your choice of Android, iOS, or UWP
