The minimum entropy multiple model estimation algorithm(MEMM),one of variable structure multiple model estimators(VSMM),is an effective approach in handling the problems with high mode ***,the performance of MEMM will deteriorate when the real observation errors are in disaccord with the prior observation error *** this end,we propose the k-means entropy multiple-model estimation algorithm(KMEMM) to refine the model sequence set adaptation ***,the k-means algorithm is employed to make several model sequence ***,the minimum entropy cluster is selected as the best model set and at last the Bayesian estimation is calculated based on *** simulation results demonstrate the efficiency of the proposed algorithm through comparing to several existing algorithms.

The intersection models, such as delay models and queuing length models, are the foundations of optimal signal timing for urban intersection. Lack of the field data of intersection, it is highly difficult to calibrate parameters of the intersection models. Due to the effects of intersection topology, channelization and traffic conditions on these models, obviously it is impossible for single model to be suitable for optimal control of various intersections.

Budget optimization is an important issue faced by advertisers in search auctions,and has significant impact on the design of various advertising *** a limited budget on a search market during a certain period,an advertiser has to distribute her budget to a series of sequential temporal slots(i.e.,days,weeks,or months),during which advertisers must avoid the budget being used up quickly,so as to keep the budget for potential clicks with better performance in the *** the optimal budgets over these temporal slots as fuzzy variables,we establish a two-stage fuzzy budget allocation model,and use particle swarm optimization(PSO)algorithm to solve it in case when these optimal budgets are characterized by discrete fuzzy *** also conduct experiments to validate our model and *** experimental results show that our model can outperform other five budget allocation strategies in terms of reducing the revenue loss of the advertiser.
