Hi,

I'm trying to understand how did you implement MPR but I am a little bit confused. Could you please give the pseudo code for MPR?. I will implement for my binary only dataset with PySpark ALS. Thank in advance.

Best wishes,
Ahmet

@ahmetlekesiz You can find some explanation here https://stats.stackexchange.com/questions/460166/mean-percentage-ranking-in-implicit-feedback-als I agree that the Spark implementation is not the most readable way to do this. Check also the links I provided in the notebook.
