Chapter 4: Building and Training a Feedforward Neural Network

In Chapter 3, Getting Started with Neural Networks, you learned the basic theory behind neural networks and deep learning. This chapter sets that knowledge into practice. We will implement two very simple classification examples: a multiclass classification using the iris flower dataset, and a binary classification using the adult dataset, also known as the census income dataset.

These two datasets are quite small and the corresponding classification solutions are also quite simple. A fully connected feedforward network will be sufficient in both examples. However, we decided to show them here as toy examples to describe all of the required steps to build, train, and apply a fully ...

Julian F.

Head of Cybersecurity

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.

Addison B.

Field Engineer

I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.

Amir M.

Data Platform Tech Lead

I'm always learning. So when I got on to O'Reilly, I was like a kid in a candy store. There are playlists. There are answers. There's on-demand training. It's worth its weight in gold, in terms of what it allows me to do.
