I see that in wooflixcli you are importing the Recommender module, which I can't seem to find in the source you provided. Am I missing something ? Thanks in advance. Hi there,

I’m trying to understand the svd++ algorithm for my masters thesis and I’m looking at your implementation.
I see that in wooflixcli you are importing the Recommender module, which I can’t seem to find in the source you provided.

Am I missing something ?

Thanks in advance.

I'm not sure, but I think I found something maybe wrong, in the predict_rating() method at a certain point you wrote: ... # Finally, the prediction: preferences = user.factors_vector.multiply_by_list(implicit_prefences, self.session) ... shouldn't there be a sum operation between vectors instead of a multiply? hi, I’m trying to figure out your code implementing svd++ in matlab enviroment..
I’m not sure, but I think I found something maybe wrong,
in the predict_rating() method at a certain point you wrote:
…
# Finally, the prediction:
preferences = user.factors_vector.multiply_by_list(implicit_prefences, self.session)
…

shouldn’t there be a sum operation between vectors instead of a multiply?
