Funtikov V. A., Nadeev D. N., Ivanov A. I. The set of gauges entropy estimation taking into consideration their data correlation


It is shown that the account of potential possibilities of the neuronet processing of the set of gauges controlling some complicated multidimensional process, can be estimated using an estimation of their overall entropy. For this purpose it is necessary to estimate average entropy of a considered field of gauges and also average value of the module of pair correlation coefficient of data from gauges outputs. There is the interrelation nomographic chart of the set of gauges entropy value as a function of gauges amount and average value of their pair correlation modules.
