Hello,
i have a questions regarding this tutorial:
  
      

      TensorFlow
  

  
    

Taking advantage of context features  |  TensorFlow Recommenders 3



  

  
    
    
  

  


what recommendation model does this tutorial based on? is it Collaborative Filtering?
and if so why does it not use the ratings in the dataset used?
how did the model come up with the recommendation given, without the rating?
