The purpose of establishing buffer operators is to improve the smooth degree, then increase the simulation accuracy of the model. This paper probed into modeling mechanism of several typical buffer operators such as the arithmetic buffer operators, the buffer operators with monotonic function and weighted buffer operators. The results indicates that after infinite buffer operators, no matter we adopt...
In this paper a generalized discrete GM(1,1) model with optimized initial value (GDGM) is put forwarded to provide the solution steps in order to solve the grey prediction modeling of non-equidistance series. This method can be utilized in solving the non-equidistance grey prediction problem with integral interval or digital interval. The GDGM model has no strict data requirement to the raw data sequence...
In many real applications, graph data is subject to uncertainties due to incompleteness and imprecision of data. Mining such uncertain graph data is semantically different from and computationally more challenging than mining conventional exact graph data. This paper investigates the problem of mining uncertain graph data and especially focuses on mining frequent subgraph patterns on an uncertain...
When GM (1, 1) model is applied to simulate a pure exponential sequence, the errors usually occur. There are many kinds of limitation to the development coefficient and the primary sequence. The characteristics of the discrete GM (1, 1) model are analogous to the GM (1, 1) model. It can be regarded as the precise form of the formal model. The paper studied the growth rate of the simulation values...
Aiming at the problem of the low accuracy predicted by the linear prediction technique of traditional Dead Reckoning in present online game, a new high-accuracy position prediction algorithm based on Dead Reckoning is proposed. The new proposed prediction algorithm uses high-order derivative polynomials to improve the prediction accuracy. The experimental results show that the algorithm is of better...
