Detailed Documentation
This study implements differential evolution optimization for extreme learning machines, where the algorithm systematically adjusts hidden layer parameters (input weights and biases) through mutation, crossover, and selection operations. The optimized ELM demonstrates marked improvement in diagnostic accuracy, achieving better generalization through refined network parameters. Additionally, the optimization process revealed inherent limitations in ELM architecture, including sensitivity to initial parameters and hidden node configuration, providing new research directions for hybrid algorithms and adaptive network structures. Future work could explore dynamic parameter adaptation and multi-objective optimization approaches to address these constraints.
