### Algorithm Suggestion for Diverging Data (Severity/Intensity Analysis)

I have four datasets for four different accidents; each dataset has the same parameters. Some of the key parameters are changing their values from a "standard value". The more they change ...

### Improving Fuzzy Logic Control System Results

I am new to using skfuzzy and the use of fuzzy logic for classification, but the results I am getting are both good and bad for some conditions. I am aware of the overarching impact the ...

### Today's practicality of Neuro-Fuzzy Systems

I am questioning today's practicality of Neuro-Fuzzy Systems (NFS), which build upon Fuzzy logic, linguistic rules, ANFIS and "standard" reinforcement learning (see this paper for a nice ...

### Choice of fuzzification function

I'm a relative newbie to fuzzie logic systems but I have some knowledge in mathematics. I have the following problem: I want to fuzzify certain values. Some are in the range [-$\inf$,$\inf$] and some ...

### Why did fuzzy logic fall out of fashion?

Fuzzy logic seemed like an active area of research in machine learning and data mining back when I was in grad school (early 2000s). Fuzzy inference systems, fuzzy c-means, fuzzy versions of the ...

### Are there real applications of fuzzy logic?

This question covers in detail, what fuzzy logic is and how it relates to other math fields, such as boolean algebra and sets theory. This question is also very related, but the answers are focused ...

### How do we decide which membership function to use?

In classical set theory, there are two options for an element. It is either a member of a set or not. But in fuzzy set theory, there are membership functions to define the "rate" of an ...

### How to determine the probability of an "existence" question

I am having a go at creating a program that does math like a human. By inventing statements, assigning probabilities to statements (to come back and think more deeply about later). But I'm stuck at ...
