To improve efficiency and classification accuracy, overcome the issue of poor generalization performance traditional fabric defect methods, we present a new algorithm with evolving Inception v3 by improved L 2,1 -norm regularized extreme learning machine. Herein, first, features images are extracted using v3, which reduces amount computation improves accuracy feature extraction. Second, an L2,1-norm regularization machine based on multi-verse optimizer–Henry gas solubility optimization,...

To mitigate the problem of low classification accuracy in solid color printing and dyeing, a difference model based on differential evolution (DE) improved whale optimization algorithm (WOA) for extreme learning machine (ELM) optimization, named DE–WOA–ELM, was developed this study. Considering that initial population WOA has significant influence solution speed quality, DE used to generate more suitable by avoiding local optima, thereby improving performance. The method an excellent global...
