Improving Prediction Of Model Gm (1, 1) Based On Class Ratio Modeling Method
نویسندگان
چکیده
This article introduces a new method of how to find suitable class ratio according to the class ratio modeling method thought. It causes the class ratio modeling method to be used on the non-steady primitive sequence which has non-homogeneous grey index law directly. And it both extends the application scope of the class ratio modeling method, and avoids the tedious data pretreatment process effectively while improving prediction precision of model GM (1, 1). Index Terms — Class ratio modeling , GM (1, 1) ,Weakening , Buffer operator

متن کاملVariable-weight Combination Prediction of Thermal Error Modeling on CNC Machine Tools
Since the thermal error modeling of CNC machine tools has characters of small sample and discrete data, the variable-weight combined modeling method was presented by integrating time series analysis and least squares support vector machines. Taking minimum sum of error square of prediction model as the optimization criterion, optimal weights in different time were calculated. Using grey GM (1, ...

متن کاملApplication of Genetic Programming to Modeling and Prediction of Activity Coefficient Ratio of Electrolytes in Aqueous Electrolyte Solution Containing Amino Acids
Genetic programming (GP) is one of the computer algorithms in the family of evolutionary-computational methods, which have been shown to provide reliable solutions to complex optimization problems. The genetic programming under discussion in this work relies on tree-like building blocks, and thus supports process modeling with varying structure. In this paper the systems containing amino ac...
