Background. The aim of the work is to create an artificial neuron, which is analogous to the "Cramer – von Mises" statistical criterion, for synthesizing neural network biometrics-code converters from these neurons.
Materials and methods. Previously the authors proved that the "Cramer – von Mises" criterion on small test samples works better than the Chi-square statistical test. It means that instead of neural network radial basis functions there can be used artificial neurons analogous to the "Cramer – von Mises" criterion. The inputs of the new type of neurons do not receive ordinary biometric parameters, but probabilities of their occurrence in a learning sample.
Results. From quadratic forms the synthesized artificial neuron inherited the learning algorithm’s stability that eliminates the problem of training large networks of neurons. As well as all quadratic neural network functionals, the "Cramer – von Mises" neuron networks give the output code with low entropy for “Foe” images due to the lack of balance of "0" and "1" states in its bits. This shortcoming is suggested to be eliminated by applying an output quantizer at the output of the "Cramer – von Mises" neuron adders with three output states.
Conclusions. The introduction of a quantizer with three stable states into the composition of the "Cramer – von Mises" probabilistic neuron allows to reach the highest level of entropy for examples of “Foe” images. This effect occurs because of the doubling of output bits of the output code and their almost total balance as of bits "0" and "1". As a result, the "Cramer – von Mises" neuron network turn out to be much more effective than other networks of other known quadratic functionals. Moreover, their output entropy code is higher than that of neural networks, formed and trained according to the state standard GOST 52633.5. This allows to examine the "Cramer – von Mises" neuron networks as a prospect for the next generation of neural network biometrics-code converters.
