A Neural Network is the basis of deep learning and the reason why image recognition, chatbots, self driving cars, and language translation.

There are millions of machine learning models out here, but neural networks in particular have gotten really popular. This is because of two things: our computers and more data. They’ve helped produce some amazing breakthroughs in everything from image recognition to generating rap songs.

When it gets down to it, there are just three steps involved in machine learning:

  1. Build it
  2. Train it
  3. Test it

Once we build our model, we can train it against our input and output data to make it better and better at pattern recognition. But, there is so much we can do to improve our current neural network… and how does it work? Join me as I build a three-layer neural network in four minutes!
