The design of digit recognition teaching experiment based on BP neural network

The teaching of pattern recognition course in postgraduates´ study is too theoretical to learn, and lack of teaching experiments. To solve these problems, this paper researches and explores on how to design digit recognition experiment in this course.we propose an digit recognition teaching plan based on BP neural network. Firstly, we summarize the development and application of digit recognition, as well as the existing problems during the teaching activities at present; then, we use the case teaching method to explain the experimental procedures,and use the method of BP neural network to recognise digit, including the principle of digit recognition, the principle of image preprocessing and the design of neural network, and so on. With the aims of optimizing the original teaching form, stimulating students´ study interests, training their abilities of practice and scientific research , we introduce the design of experiment. Finally, help students to solve practical problems..
