About the code on find_k_largest about qrec HOT 3 CLOSED

It doesn't. I just checked the code and printed the list. It works as expected. Why do you think it will append two times?

from qrec.

The for iid,score in enumerate(candidates means check the every value in candidates. While if the value is already in initial n_candidates and if the for, it will append one time again to the n_candidates. Just as the example find_k_largest(5, [1,2,3,4,5,6,7]). If the 0~K item in candidates is not the top K values, it will not affect the result.

from qrec.

r=K-1 which means that for the first K items in candidates, the following codes conditioned on L146 would not be excuted. So, there would not be repeated items in the recommendation list.

However, it would be better if it iterates in the range [K:]. Thanks. I will consider to modify it.
