Models for comparison.

ModelScaleDescription

Matrix factorization (MF)MF is widely used in CF and usually set as baseline.
Probabilistic matrix factorization (PMF)PMF is a conventional model in recommendation domain.
Factorized personalized Markov chain (FBMC)FBMC formalizes the user’s preference as a personalized Markov chain.
Tucker decomposition (TD)TD transforms the high-dimension tensor into a core tensor with a relative matrix in each dimension.
Canonical polyadic decomposition (CD)CD transforms the high-dimension tensor into a multiple equation of linear complexity.
Time-aware FBMC (TA-FBMC)TA-FBMC equips the time factor with the FBMC.
Time-aware decay FBMC (TAD-FMPC)TAD-FMPC adds decay of the probability over time in TA-FBMC.
Static prido (s-Prido)s-Prido removes the dynamic tensor structure from Prido.
