description Artificial neural network (ANN) are widely used as an engineering approach to mimic the human brain activities. It has applied in different aspects such as pattern recognition, alphabet or digit classification, handwriting recognition, speech recognition, fingerprint identification, data mining, robots and etc. Back-propagation is the most common artificial neural training algorithm, however it is suffering with the slow convergence rate issue. A study to improve the slow convergence rate of a neural network without sacrificing the accuracy of the network are carried out. In this research, a hand-written character recognition model are implemented in C++ programming with ability to classify digits 0, 1, 2, and 3.
