Appendix C:Types of Fuzzy Membership Function

There are many kinds of fuzzy membership functions. Commonly used fuzzy membership functions are mainly Z-type, S-type, the intermediate symmetric type, and so on.

1. Z-type

Z-type is also known as partial small type, and it is suitable for membership function of small u. Because the membership function distributes in the first quadrant, the values of u are positive. The descending semi-rectangular distribution, descending semi-normal distribution, descending semi-г distribution, descending semi-Cauchy distribution, descending semi-trapezoid distribution, descending semi-mountain-shaped distribution, descending semi-concave (convex) distribution, and so on belong to this class.

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.
