What Is Fuzzy Logic?

The next figure shows the model output.
The model output and checking data are shown as circles and solid blue line,
respectively. This plot shows that genfis2 can be used as a stand-alone,
fast method for generating a fuzzy model from data, or as a preprocessor to
anfis for determining the initial rules. An important advantage of using a
clustering method to find rules is that the resultant rules are more tailored
to the input data than they are in a FIS generated without clustering. This
reduces the problem of an excessive propagation of rules when the input data
has a high dimension.
Overfitting
Overfitting can be detected when the checking error starts to increase while
the training error continues to decrease.
