“…Bayesian networks are also being used to address user modeling problems in different types of systems (Heckerman, Horvitz, & Rathwani, 1989;Horvitz, Breese, Heckerman, Hovel, & Rommelse, 1998;Jameson, 1996;Vegas, 1995). Several studies conducted on the comparison of machine learning techniques used in student modeling systems show that Bayesian networks are effective for meeting the student modeling challenge (Gonzalez, Burguillo, & Llamas, 2006;Hamalainen & Vinni, 2006;Kotsiantis, Pierrakeas, & Pintelas, 2003;MinaeliBigdoli, Kashy, Kortemeyer, & Punch, 2003). Hence, a dynamic Bayesian inference mechanism for students modeling has been proposed in this study.…”
