This is my Python study files. Something about the codes, PDF files or other test files
This is my first use of github, and I use it for my python study because I am learning Python and I like it very much. It will be fine if you study with me togecher.
MNIST.py用于数据加载,实现了Loader, ImageLoader等类,main()中测试能够将手写数字数据集加载并且打印出来
DNN.py用于实现神经网络,分别实现了Sigmoid激活函数类,单层全连接层FullyConnectedLayer,以及神经网络类Network
main.py用于测试手写数字识别效果。读取6000笔数据进行训练,1000笔数据进行测试,在我的电脑上(i5,内存4G)平均每个epoch跑20秒,20次epoch就可以结束(用的是while循环,当错误率降低至0.1时停止循环)。
