In this Basic Neural Network project, the user interacts with the neural network by supplying input data for training and testing. The program outputs predicted output values generated by the neural network based on the input data provided for testing. This project provides a beginner's understandin...
test_sigmoid_basic()函数提供了几个例子用于测试前两个函数。 脚本可以被直接执行: if__name__=="__main__": 上面这行代码的作用是“让你写的脚本模块既可以导入到别的模块中用,另外该模块自己也可执行。”(“Make a script both importable and executable”)如果还是不太明白可以看这篇文章。 importnumpy...

As we’ve seen in the sequential graph above, feedforward is just simple calculus and for a basic 2-layer neural network, the output of the Neural Network is: 正如我们在上面的序列图中看到的,前馈只是简单的计算,对于简单的的 2 层神经网络,神经网络的输出是: 让我们在 python 代码中添加一个前馈...
