Abstract: This paper proposes a new training algorithm for artificial neural networks based on an enhanced
version of the grey wolf optimizer (GWO) algorithm. The proposed model is used for classifying
the patients of diabetes disease. The results showed that the proposed training algorithm enhanced
the performance of ANNs with a better classification accuracy as compared to the other state of art
training algorithms for the classification of diabetes on publicly available Pima Indian Diabetes (PID)
dataset. Several experiments have been executed on this dataset with variation in size of the population,
techniques to handle missing data, and their impact on classification accuracy has been discussed.
Finally, the results are compared with other nature-inspired algorithms-trained ANN. EGWO attained
better results in terms of classification accuracy than the other algorithms. The convergence curve
proved that EGWO had balanced the local and global search abilities because it was faster to reach
better positions than the original GWO.
