“…The latter are artificial intelligence data-driven methods. More specifically, this category includes machine learning techniques, including the commonly used artificial neural networks (Coulibaly et al, 1999;Maier & Dandy, 2000;Maier et al, 2010; ∼65% of the referenced studies), fuzzy inference systems (Özger, 2009), evolutionary computation with genetic programming (Charhat et al, 2009) and other techniques, such as wavelet-based artificial intelligence techniques, hidden Markov chain models and chaos theory (Cui & Singh, 2015;Fortin et al, 2004;Liu et al, 2014).…”
