Chapter 9

Hybrid Systems

9.1 Convergence of Techniques

The previous chapters of this book have demonstrated that there is a wide variety of computing techniques that can be applied to particular problems. These include knowledge-based systems, computational intelligence methods, and conventional programs. In many cases the techniques need not be exclusive alternatives to each other but can be seen as complementary tools that can be brought together within a hybrid system. All of the techniques reviewed in this book can, in principle, be mixed with other techniques. This chapter is structured around four ways in which different computational techniques can be complementary:

Dealing with multifaceted problems. Most real-life problems are complex ...

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.
