【Abstract】 Handwritten numeral recognition deals with the information of taxation,finance and other fields through computer or other machines for processing,makes it possible to save manpower and financial resources,with higher practical value.Although the type of identification number is not much,the required accuracy is very strict.Introduces the basic principle of probabilistic neural network,applies probabilistic neural network to handwritten digit recognition to select the best network diffusion speed and the number of training samples,and realizes the digital identification based on probabilistic neural network.MNIST handwritten database through MATLAB simulation experiment,the results show that the algorithm has high recognition rate,which is feasible and effective.更多还原
