Practice model recommending e-commerce products to users
I was just running the additional practice model "Recommending e-commerce products to users" in the AI4I Basics.
After this is added the "Evaluate Recommender" module to the training experiment to see how good the scores would be.
Unfortunately get an error message saying the test data contains invalid data. I just connected it the same way as the movie recommender experiment.
Any idea why that happens?
