Abstract:
In this article the results of statistical analysis of neural network (NN) with LMS algorithm tuning with square constraint for weight coefficients jitter are represented. The task was solved by the methods of perturbation theory for the coefficient adap-tation of the LMS algorithm with quadratic constraint, which was supposed to be small. The result are presented in the first (born) approximation. The expressions for output power of some neuron of the different neural network layers are obtained. It is shown, that the weight vector jitter leads to distortions of output signal of neural network and these distortions depends on number of neural network layer.
