About the CNN features of the image dataset

[MiracleWc]

There are doubts about the CNN features of the image dataset mentioned in your article. Are you using a base model (such as torchvision.models.resnet18(pretain=True) or others) to extract features or a custom CNN module？ In my experiment, I found that different feature extractions still have a great impact on the results. Looking forward to your reply

We extract image features by VGG16 network without pre-training and use the Gaussian kernel function to construct the adjacency matrix.
