Review on the Recent Welding Research with Application of CNN-Based Deep Learning Part II: Model Evaluation and Visualizations

With the development of deep learning technology, research on classification and regression models welding phenomena using convolution neural networks (CNNs) are gradually increasing. Part 1 this study introduced characteristics CNNs their application to studies. In paper, we reviewed recent papers analyze how evaluate CNN visualize modeling output, details evaluation index, comparison models, visiualization methods were explained. Key words: Deep learning, Convolution Neural Network, Image, Welding, Evaluation, Visualization
