    Area of Science:

    • Computational Intelligence
    • Machine Learning
    • Fuzzy Systems

    Background:

    • Genetic fuzzy rule extractor (GEFREX) is a genetic-neuro-fuzzy algorithm.
    • Crossover operators are crucial components in genetic algorithms for exploration and exploitation.
    • Existing GEFREX implementations may have suboptimal learning times.

    Purpose of the Study:

    • To introduce and evaluate novel crossover operators for the GEFREX algorithm.
    • To improve the computational efficiency of GEFREX, specifically focusing on reducing learning time.
    • To demonstrate the impact of simple genetic algorithm enhancements on complex neuro-fuzzy systems.

    Main Methods:

    • Implementation of several new, simplified crossover operators within the GEFREX framework.
    • Comparative analysis of the performance of GEFREX with standard and improved crossover operators.
    • Evaluation metrics focused on learning time and algorithm convergence speed.

    Main Results:

    • The newly developed crossover operators led to a significant reduction in the learning time of GEFREX.
    • Despite their simplicity, the improved operators enhanced the overall performance of the algorithm.
    • The findings indicate that focused improvements in genetic operators can yield substantial gains in efficiency.

    Conclusions:

    • Simple modifications to the crossover operator can markedly enhance the learning speed of the GEFREX algorithm.
    • The study validates the effectiveness of targeted genetic operator improvements for neuro-fuzzy systems.
    • These findings suggest a practical approach to optimizing genetic-neuro-fuzzy algorithm performance.
