To enhances the user-oriented characteristics of information form of PDM system, and makes the message retrieval more convenient and efficient and the PDM products more competitive. In this paper, for the user diversified needs of products information, the design of personalized retrieval systems of products information was realized by adopting the method of controllable automatic modeling process...
Towards a special class of hybrid systems, the hybrid systems with impulses and switches, a global optimal control problem with free system terminal states is proposed in this paper. Based on this problem, the necessary condition is studied, and then the HISS' minimum principle is obtained. In the proof of the above theorem, the general variational methods and matrix cost functional formulations are...
Web search engine companies are intensively running learning to rank algorithms to improve the search relevance. Neural network (NN)-based approaches, such as LambdaRank, can significantly increase the ranking quality. While, their training is very slow on a single computer and inherent coarse-grained parallelism could be hardly utilized by computer clusters. Thus an efficient implementation is necessary...
The interpretation of aerial images is difficult, especially for low-resolution images. Although solutions have been worked on for many years, performance of these systems is still not sufficient to be useful in practical applications. One potential solution is to create systems composed of many specialized modules. We introduce one such module, a Bayesian tracker for linear structures, such as pipelines...
