In recent years many other matrix factorization models have been developed to exploit the ever increasing amount and variety of available interaction data and use cases, for example, group-specific matrix factorization<ref>{{cite journal|last1=Bi|first1=Xuan|last2=Qu|first2=Annie|last3=Wang|first3=Junhui|last4=Shen|first4=Xiaotong|year=2017|title=A group-specific recommender system.|url=https://amstat.tandfonline.com/doi/abs/10.1080/01621459.2016.1219261|journal=Journal of the American Statistical Association|publisher=|volume=112|issue=519|pages=1344-1353|doi=}}</ref>.
