i stand on what i've posted. it's not argued from the perspective of 'neural
network theory'. it stands verified via Neuroscience experimental results.
the nervous system 'recognizes' 'relative-appropriateness' in the relative
'shortness' of circuits within the 'momentary' activation 'state'.
that's 'just' another way of viewing TD E/I-minimization... 'randomness'
lengthens circuit-routing within the nervous system.
as 'randomness' is eliminated, circuit lengths decrease.
it's the same at all 'levels', right down to the DNA.
