Hello,

With this repo, is there an easy way to get the local Lipschitz constant of a customized Pytorch CNN on a given image, using the RecurJac method? Thanks.

Hello,

I'm interested in running your certifiable robustness code on a small network (MobileNetV2) that I've trained on CIFAR10. I noticed you have instructions on how to train a network to then certify, but what code should I modify to use my own network?

Can you tell me in which article I can see the details of the crown_adaptive_bound

Why should back propagate to the first layer to calculate Global bounds by Λ(0) and Ω(0)？will the Global bounds obtained this way be more accurate（tighter）?

I would also like to ask if the “crown-interval" in this code can support CROWN-IBP type of robustness boundary calculation?
And in "boundary_base.py line 188", when determining "layerbndalg == "crown-interval"", is it only for ReLU activation function? Why do I need to call crown_adaptive_bound after interval_bound？is this a CROWN-IBP-like boundary calculation?
