In this paper, we study the performance of mean square error (MSE) and Gaussian entropy criteria for linear and widely linear complex filtering. The MSE criterion cannot exploit the full second-order statistics of the error signal. To this end, we propose a new Gaussian entropy criterion to exploit the full second-order statistics of the error signal, and compare the performance of the two criteria...
Fuzzy error matrix based on fuzzy error logic is used to express current status u, expectant status u1 and transformation matrix T. It is u,u1, and T that are used to build fuzzy error matrix equation T(u)=u1. It allows us to find a method that bad status “u” change to good status “u1” by solving equation. The purpose of solving fuzzy error matrix equation is to get a decision support about how to...
In order to eliminate the influence of incomplete sample data in fault diagnosis, Bayesian theorem is used for the design of Petri nets diagnostic model. Firstly, the concept about probability Petri net is defined. It can calculate the occurred probability of the absent datum based on Bayesian theorem from the detected attributes. Secondly, for the complicated Petri nets will induce the combinatorial...
