“…Research on click prediction focus on developing various models, including Logistic Regression (LR) [8,23,27], Polynomial-2 (Poly2) [6], tree-based models [16], tensor-based models [26], Bayesian models [13], Field-aware Factorization Machines (FFM) [18,19], and Field-weighted Factorization Machines (FwFM) [24]. Recently, deep learning for CTR prediction also attracted a lot of research attention [9,14,15,25,29,30,32].…”
