Is it a bug?

Hi Prof Yuan~

In the evaluation part of PeterRec_cau_serial.py line 243, the rank of the retrieved items is given by
rank = predictmap.get(negtive_samples)
where negtive_samples is 'the number of negative examples for each positive one'.

Is it a bug? How can negtive_samples be the key of a retrieved item?

Hi it is not a bug. If I remember correctly, negtive_samples means the index of the target item.

Can you please check again? I have printed the value of negtive_samples for every iteration and it's always 99 (same as the negtive_samples argument).

[fajieyuan]

the last index 99 is always the target item,

I see. I didn't notice it was the top-k retrieval within the batch. Sorry for the bothering~
