“…The ANNs, and in particular, the feed forward backward propagation perceptrons, are widely applied in different fields during the past decade (Arditi et al, 1998;Thirumalaiah and Deo, 1998;Chau and Cheng, 2002;Cheng et al, 2005;Lin et al, 2006;Muttil and Chau, 2006;Wu and Chau, 2006;Xie et al, 1006;Chau, 2007). It appears that the multi-layer perceptrons can be trained to approximate and accurately generalize virtually any smooth, measurable function whilst taking no prior assumptions concerning the data distribution.…”
