Description
Hi,
We introduced two novel collaborative filtering techniques for recommendation systems in cases of various cold-start situations and incomplete datasets.
The first model z-scoREC establishes an asymmetric weight matrix between items without using item meta-data and eradicates the disadvantages of neighborhood approaches by automatic determination of threshold values.
The implementation of z-scoREC model is implemented in this PR.
