编写简单的神经网络程序，使得通过神经网络对手写数字（将手写每个数字转换成784个数字表示）进行识别。在文件里放了100组训练集和10组训练集，训练准确率达到80%。事实证明，增大训练集至1000组可以将准确率提升至95%(Write a simple neural network program to recognize handwritten digits (converting each handwritten digit into 784 digital representations) by neural network. In the document, there are 100 training sets and 10 training sets, and the training accuracy rate reaches 80%. It has been proved that increasing the training set to 1000 groups can increase the accuracy rate to 95%.)
