“…Quantitative methods and models that have been proposed for the assessment can be divided into methods of statistical analysis (Sari et al, 2017), mathematical models (Akgun et al, 2012) and machine learning (He and Fu, 2009). However, most of these methods are subjective, such as expert evaluations, analytical hierarchy processes, logistic regressions and fuzzy integration methods, which could affect the accuracy and reasonableness of the evaluation (Fall et al, 2006;Sarkar and Gupta, 2005). This shortcoming can be overcome through the artificial neural network, especially the mature back propagation (BP) neural network that is widely used in function approximation and pattern recognition (Ke and Li, 2014a;Li et al, 2013;Su and Deng, 2003).…”
