This paper [1] models some simple (r) NN as ODEs, and uses ODE tools to train and for inference. It’s a start. [1] https://arxiv.org/abs/1806.07366

Really great research work from Kay Ousterhout. Sparrow extends the "power of two choices" [1] to a more general formulation, and makes it really cheap to find very good choices (i…

Also, don't call from the same phone you received the call on, if on a landline . One time (I can't find the reference) scammers called from the bank, suggested the person called b…
