“…Several studies have focused on investigating two-phase flow in natural circulation using artificial intelligence techniques, such as Fuzzy Logic (de Mesquita et al, 2012;Ghanbarzadeh et al, 2012;Shi, 2007), as well as traditional machine learning methods based on feature extraction. These include Principal Component Analysis (PCA), Support Vector Machine (SVM) (Huang et al, 2011;Shanthi and Pappa, 2017;Xiao et al, 2018).…”
