An enhanced feed-forward neural networks and a rule-based algorithm for predictive modelling of students' academic performance

Feed-forward Neural Networks, is a multilayer perceptron and a network structure capable of modelling the class prediction as a nonlinear combination of the inputs. The network has proven its suitability in solving several complex tasks. But sometimes, it has challenges of over-fitting, especially w...
