Digital Recognition Methods Based on Deep Learning

Table 1

Recognition rates at different K values and training set sizes.

K	2	3	4 (%)	5 (%)
5000 training images	89%	92%	88	92
10000 training images	91%	96%	94	94

The convolutional neural network training results with only one convolutional layer and one pooling layer are as shown in Table 2.
