Before revision:  However, because the researched problems are most slightly changed process , the low-accuracy of the Convolutional Neural Network (CNN) and poor-diversity of the Generative Adversarial Network (GAN) make the reconstruction process low-accuracy, poor-efficiency, expensive-computation , and high-manpower.
