The author starts talking about the existence of backdoors in pretrained models and begins by giving an example of a model called CLIP and some of the things it mis-identify. When the example finally reaches a point about backdoors and security, that point has nothing to do with the model itself, but is a general complaint about the internet of things. Is it possible to build backdoors into pretrained NN-models?
