In ML there is usually used normalization by subtracting the mean and dividing by standard deviation - I haven't seen by CDF in ML (?, they are popular in finance for copulas: https://en.wikipedia.org/wiki/Copula_(

Just represent joint density for each neuron as a linear combination - then you can inexpensively propagate in both directions e.g. as E[X|Y,Z] or E[Y,Z|X] by substituting and normalizing ... the formulas turn out quite simple - could be hi

Sure biological NN are much more complicated, but basically action propagation can travel in both directions, and evolution should optimize for that. In contrast, current ANNs are focused on unidirectional propagation, and are much worse at

(Multidirectional) biological neural networks are no longer superior in MNIST benchmark ... but e.g. consciousness, or being able to learn from single examples. And no, recreating it is not a task a single person can complete.

Which benchmarks for multidirectional neurons? To compare with which approaches? Multidirectional are biological neurons, but I don't know how to compare with them?

There is a dozen of papers in this methodology (e.g. end of https://community.wolfram.com/groups/-/m/t/3017754 ), but not as ANN. However, it degenerates to ~KAN if restring to pairwise dependencies (can

While ANNs are rather trained for unidirectional propagation, action potential propagation in biological neurons is symmetric e.g. ”it is not uncommon for axonal propagation of action potentials to happen in both directions” ( https:/

For more than half a century they unsuccessfully try to unify Standard Model with gravity ... doesn't it mean that at least one of them is inaccurate? https://en.wikipedia.org/wiki/Quantum_gravity#Nonrenormaliza...

Indeed baryogenesis is one example of baryon number violation, another is Hawking radiation - baryons forming stars and finally ending as massless radiation. In both these examples conditions are completely extreme - what might be the missi
