In this chapter, we laid the foundation of neural networks and walked through the simplest artificial neural network. We learned how to build a single layer neural network using TensorFlow.
We studied the differences in the layers in the Keras model and demonstrated the famous handwritten number recognition with Keras and MNIST.
Finally, we understood what backpropagation is and used the MNIST dataset to build our network and train and test our data.
In the next chapter, we will introduce you to CNNs.
