Personal mobile devices (PMDs) have become the most used computing devices for many people. With the introduction of mobile cloud computing, we can augment the storage and computing capabilities of PMDs via cloud support. However, there are many challenges in developing mobile cloud applications (MCAs) that incorporate cloud computing efficiently, especially for developers targeting multiple mobile...
According to Principle of New Information Priority in grey theory, giving the new information larger weight in modeling can improve the effectiveness of gray model. For the GM (1, 1)model has very small samples, and the high overall simulation accuracy does not necessarily guarantee high prediction accuracy, we put forward weighted least square method to estimate parameters in GM (1, 1) model. Focusing...
The guidelines for the construction of the data transformation have been proposed in the paper based on the mechanism, and a new type of transformation was constructed. A number of properties of the new transformation also have been discussed. A new GM (1, 1) model based on the new transformation is established. It is proved that the prediction accuracy of GM (1, 1) can be improved by the new transformation...
We search for an improved gray GM (1,1) model by data processing. First, a number of properties of generation by weighting are proved, and then weighting generating is applied to GM(1,1). Calculation result indicates that weighting GM(1,1) model is improved and precision is increased. This indicated that weighting GM(1,1) model has better applicability.
The grey forecast is one of the important parts in grey systems theory. According to the theory of prior using of new information, based on the present theories of buffer operators and some already existed weakening buffer operators, some new weakening buffer operators are established. Meanwhile, they are compared with the existing weakening buffer operators in effectiveness. The problem that there...
