There are a lot of different kinds of neural networks that you can use in machine learning projects. There are recurrent neural networks, feed-forward neural networks, modular neural networks, and more.
Convolutional neural networks are another type of commonly used neural network. Before we get to the details around convolutional neural networks, let's start by talking about a regular neural network.
