The data mining technology is more and more widely used in the telecom industry. When we construct Bayesian Belief Network, the branch and bound technique based on the minimum description length principle (B&B technique) is one of the classical algorithm. To telecom data, high dimensionality and huge volume set obstacle when constructing Bayesian Belief Network. But we utilize the inconspicuous...
In view of the existing limitations in the process of informatization level measuring for enterprises at home and abroad, as well as the particularity of manufacturing enterprises, a measuring indicator system of informatization level in manufacturing enterprises, which is composed of production and management informatization, is established in this paper. In consideration of hardly being accurate...
Aimed at the feature of various fieldbus standards and types as well as the selection and evaluation problems confronted with users, the entropy-ideal point method is used for reference in this paper. A fieldbus comprehensive evaluation and selection method that combined fieldbus technical features and based on fieldbus static performance index is proposed, and the corresponding evaluation model is...
In this paper, we propose a method for DS-CDMA delay estimation through the use of the downlink channel character. This method is based on Independent Component Analysis using the conjugate descent algorithm to estimate the multi-path mixture matrix and find the delay information which is embodied by the column vector of the mixture matrix using both the independence of information source and the...
Information entropy is an effective description for the uncertainty of a system, and could be used for the symptom to detect the vibration changes of steam turbine. Based on the faulty signals collected from rotor test rig, three information entropy: singular spectrum entropy, power spectrum entropy, wavelet energy spectrum entropy were calculated as information entropy data. Probability neural networks(PNNs)...
