“…One of the most important NFS algorithms is Adaptive‐Network‐based Fuzzy Inference Systems (ANFIS; Jang, 1993), which has been used in a wide range of applications (Bonisone, Badami, & Chiang, 1995). The combination of NN and fuzzy sets offers a powerful method to model human behavior, which allows NFS to be used for a variety of user modeling tasks (Drigas, Kouremenos, S., Vrettos, Vrettaros, & Kouremenos, D., 2004; Lee, 2002; Magoulas et al, 2001; Stathacopoulou, Grigoriadou, & Magoulas, 2003).…”
