5 Improving the Performance of Machine Learning Models

In the previous chapter, you learned about different techniques for properly validating and assessing the performance of your machine learning models. The next step is to extend your knowledge of those techniques for improving the performance of your models.

In this chapter, you will learn about techniques to improve the performance and generalizability of your models by working on the data or algorithm you select for machine learning modeling.

In this chapter, we will cover the following topics:

Options for improving model performance
Synthetic data generation
Improving pre-training data processing
Regularization to improve model generalizability

By the end of this chapter, you will be ...

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.
