“…Further, application of B-spline functions for least square fitting is presented in (Zhou et al, 2009), while spectrum fitting using Levenberg-Marquardt optimization is discussed in (Fatah & Ahmed 2011). Genetic algorithms are adopted for searching for an optimal combination of template spectra in (Carlevaro et al, 2008), and fuzzy logic based approaches in (Alamaniotis et al, November 2009) and (Alamaniotis et al, January 2014), while a hybrid evolutionary-fuzzy in (Huang et al 2011). Other proposed methodologies employed Bayesian Statistics such as the work described in (Stinnett & Sullivan, 2013), likelihood ratios (Forsberg et al, November 2009), Local-Global graphs (Bourbakis et al, 2008), and neural networks (Yoshida et al, 2003).…”
