Based on Lukasiewicz's three-valued logic,this paper builds a tri-ary uncertain reasoningmodel,and discusses its some basic properties which shows that it is consistent with our intu-itions. The characters of our model are as follows: 1)its measure for uncertainty is a distribution onthe true-value set of the multi-valued logic, 2)its propagation for uncertainties is related with theoperation of the logic,and 3) its parallel propagation follows a consertative principle 相似文献

Regularized system identification has become the research frontier of system identification in the past decade. One related
core subject is to study the convergence properties of various hyper-parameter estimators as the sample size goes to infinity.
In this paper, we consider one commonly used hyper-parameter estimator, the empirical Bayes (EB). Its convergence in
distribution has been studied, and the explicit expression of the covariance matrix of its limiting distribution has been given.
However, what we are truly interested in are factors contained in the covariance matrix of the EB hyper-parameter estimator,
and then, the convergence of its covariance matrix to that of its limiting distribution is required. In general, the convergence
in distribution of a sequence of random variables does not necessarily guarantee the convergence of its covariance matrix.
Thus, the derivation of such convergence is a necessary complement to our theoretical analysis about factors that influence
the convergence properties of the EB hyper-parameter estimator. In this paper, we consider the regularized finite impulse
response (FIR) model estimation with deterministic inputs, and show that the covariance matrix of the EB hyper-parameter
estimator converges to that of its limiting distribution. Moreover, we run numerical simulations to demonstrate the efficacy
of our theoretical results. 相似文献

The quality of skeleton system for the cheetah robot goes hand in hand with its bionic result of its shape, structure and functions. In view of the skeleton system constitution and structural characteristic of the cheetah, the team applied structure design, stimulation analysis and parameter optimization to developing the cheetah robot. In addition, after the invention of cheetah robot's anterior lumbar vertebra based on its functional attribute and connectivity attribute, the Solidworks Simulation was utilized to analyze the design, according to which improvement on the lumbar vertebra was made. Plus, the advantages of the CAD and CAE made the high efficiency of design work and high quality of the cheetah robot possible. 相似文献
