In the procedure of China's market-oriented reforms of interest rates, the interest-rate risk becomes increasingly apparent. Analyzing the existing studies and the interbank offered rate trend, this paper finds that LS-SVM, which is short for Least Squares Support Vector Machines, is excel in nonlinear data approximation, which is suitable for interest rate forecasting. Firstly, the paper established...
The ranking interval number method is adopted for chemical oxygen demand production coefficient forecasting. It could be added to the fuzzy Bayes analysis model. The forecasting model is present. It could make Bayes risk decision making more practical. Financial factor of dyeing enterprise combining with COD experimental setting is adopted for COD forecasting. The standard and extension chemical oxygen...
This paper presents a hybrid short-term traffic flow forecast technology. For the uncertainty, the short-term traffic flow forecast is complicated, and the accuracy is not high. This strategy combines the RBF neural network and ant colony clustering algorithm to forecast the traffic flow. It used ant colony clustering algorithm to get the centers of hidden layer neurons. To find the best clustering...
Acid fracture treatment is one of the most effective way of stimulation in fractured and cavernous carbonatite reservoir. Because there are too many factors that influence the acid fracture effect, such as geologic factor, technic factor, material's factor, it is difficult to forecast the effect of acid fracture before the treatment has been done. The relationship between these factors and result...
