I still can't understand your paper very well due to lack of knowledge of topology.
Have you ever written some blogs or guides about this paper?
I want to understand the paper more clearly.thank you！

I also would like to understand better how the topological loss is differentiable. They give hindsight as to why birth/ death of a particular betti number is differentiable w.r.t pixel value but i am not sure what is the analytical derivation for this. I mean it looks like a heavyside (step) function which to me is not really differentiable (=0 or infinity)
