ECDSA Discrete Analysis FFT/RNN-LSTM anybody play with this stuff here?

[bitfools]

I was kind of curious the status of looking at patterns of ecdsa priv/pub sig pairs using machine-learning, curious if others here were doing the same, I don't see much in the literature, just curious about what others are finding.

Most of my research is on looking for group-clusters and developing discrete-log algo's, anybody else using ML to do this stuff?
