In this sample, you can see how to use ML.NET to build a product recommendation scenario.

The style of recommendation in this sample is based upon the co-purchase scenario or products frequently
bought together which means it will recommend customers a set of products based upon their purchase order

The difference between one-class and other Factorization Machines approach we covered is that in this dataset we only have information on purchase order history.
