【Abstract】 To investigate the application of back-propagation algorithm to the recognition of handwritten Chinese characters, the principle of artificial neural network and Back-propagation algorithm are discussed. Then the problems that handwriting Chinese characters’ recognition meets are descrlbed and the techniques that it uses are introduced. And handwritten Chinese characters’ recognition using BP algorithm in detail is also analyzed. Finally the improvement to BP algorithm is introduced.更多还原
