There are so many CNNs out there and im trying to do a comparison between some of them in my paper which networks should I use? Resnet, vgg and inception are obvious but I need 3 or 4 others. which ones should I choose? There are so many variations out there like Xception ,resnext and ... that im confused. Which of these networks are most used in the academic papers?
It largely depends what kind of paper you are writing — you haven't provided too much information in that regard. You could discuss a selection of models that have scored the highest on ImageNet. Most of these networks have historical significance, and brought a new aspect to the table.
