I can't check everything right now, but for example, the divulgational from Rakesh Kumar mentiones "Analogue CIM".

And I do not get your rant about "analog computing", which has everything to do with NNs (otherwise, well, prove it): they started with that - they are basically that in fact. Analogue computing is a very great temptation since it would solve the issues of inefficiency in digital NNs. Unfortunately, it has drawbacks which are massive for big NNs. Taalas' seems to be the best compromise.
