Neural Networks and Deep Learning编程作业 (Week 3)

一.###

1.plt中的scatter函数

2.X.shape属于X的属性,可以直接写出使用,而不是方法,后边可以不加()

二、构建神经网络模型

1. Define the neural network structure ( # of input units,  # of hidden units, etc). 
2. Initialize the model's parameters
3. Loop:
    - Implement forward propagation
    - Compute loss
    - Implement backward propagation to get the gradients
    - Update parameters (gradient descent)

4.进行预测
