Description
What is the different between k and threshold value here if they all get assigned to top_k? Isn't threshold supposed to be a rating value that the predictions should exceed instead of being the number of items in the top_k list ? Thanks.

if relevancy_method == "top_k":
top_k = k
elif relevancy_method == "by_threshold":
top_k = threshold
