Neural network (2 layer)
It's time to build neural network, with one hidden layer. You will see that there is no big difference between this model and logistic regression.
NN forward prop and cost
In previous tutorial we initialized our model parameters. In this part we'll for this we'll use cache computed during forward propagation.
NN backward propagation
In this tutorial part we'll write backward propagation and parameters update function using cache computed during forward propagation.
