Implementing Our First Neural Network

Let’s implement a neural network. Specifically, we will implement a fully connected neural network (FCNN) model.

One of the stepping stones to the introduction of neural networks is to implement a neural network that is able to classify digits. For this task, we’ll be using the famous MNIST dataset.

We might feel a bit skeptical regarding our using a computer vision task rather than an NLP task. However, vision tasks can be implemented with less preprocessing and are easy to understand.

Because this is our first encounter with neural networks, we’ll see how to implement this model using Keras. Keras is the high-level submodule that provides a layer of abstraction over TensorFlow. Therefore, we can implement neural networks with much less effort with Keras than using TensorFlow’s raw operations.
