Adaptive fuzzy systems

Definition

Adaptive fuzzy systems are intelligent systems that combine fuzzy logic with adaptive learning mechanisms to adjust their parameters and rules based on changing input data or environments. This flexibility enables these systems to improve their performance over time, making them particularly useful in dynamic and uncertain situations where traditional models may struggle.
