This article will deeply analyze the underlying reasons for the decline in CNN research popularity and the development direction of this classic architecture in the new era.In the field of deep learning, Convolutional Neural Networks (CNNs) were once synonymous with computer vision. Since AlexNet’s groundbreaking success in the ImageNet competition in 2012, CNNs have sparked a revolution in image recognition, object detection, and other areas. However, looking at recent top conference papers and research hotspots, we must acknowledge a reality: the number of research papers related to CNNs is decreasing, and the once
