短句来源
     Based on the fact that “short circuit” edges pass the area with the relatively lower local densities, this paper presents a new variant of ISOMAP, i.e. P-ISOMAP (pruned-ISOMAP), which can prune effectively “short circuit” edges existed possibly in the neighborhood graph and thus is much less sensitive to the neighborhood size and more topologically stable than ISOMAP.
     然而,如何有效地选取合适的邻域大小,目前还是一个尚未解决的难题. 根据“短路”边会途经相对的低密度区域这一特点,能够有效删除邻域图中可能存在的“短路”边,提出了P-ISOMAP(pruned-ISOMAP)算法,这极大地削弱了ISOMAP算法对邻域大小的依赖程度,从而使其更具拓扑稳定性.

In this paper, a new algorithm for constructing the relative neighborhood graph(RNG) of ann points set in Euclideank-dimensional space is presented, for fixedk≥3.
      
We prove that, for broadcasting, the relative neighborhood graph (RNG), which is the previously best-known sparse structure that can be constructed locally, could use energy O(n) times the total energy used by our structure LRNG.
      
In the Z2 case, this leads to an extension of the neighborhood graph of the even self-dual lattices in 24 dimensions to conformal field theories, and we demonstrate that the graph becomes disconnected.

It is necessary to access non-formatted information such as image and to process a mass of data fusion in the Remote Sensing Interpretation System. So we build a database system for remote sensing application to manage data effectively and to access data friendly, and this system provides data for Remote Sensing Interpretation System. When we present RSID, Remote Sensing Image Database, we consider the safeness, integrity, reliability and SQL function of RDBMS and the effective management formatted data, and combine the simulation and operations of a great deal of non-formatted and complex object of the OO language in Remote Sensing application, and integrate the merit of RDBMS and OO language, and uniformly manage remote sensing data, circumstance information and subject attribute information. At last we point out the limitation of kNN retrieval model in CBIR, then introduce the relative neighborhood graph retrieval model to satisfy better remote sensing image retrieval. In order to provide the access to database and to improve the safeness of data, we build remote sensing interfaces. Our RSID provides the support of database for image interpretation.

The success of ISOMAP depends greatly on choosing a suitable neighborhood size,however,it is still an open problem how to do this effectively.Based on characteristics of the SOMST(Second-Order Minimal Spanning Tree) in which shortcut edges can be avoided,this paper presented a variant of ISOMAP,i.e.PISOMAP(Pruned-ISOMAP).P-ISOMAP can prune effectively shortcut edges existed possibly in the neighborhood graph according to their costs over the SOMST,and thus is much less sensitive to the neighborhood size than ISOMAP.Consequently,PISOMAP can be applied to data visualization more easily than ISOMAP for the open problem described above can be avoided to a certain extent;in addition,P-ISOMAP can also be more topologically stable and robust than ISOMAP.Finally,the feasibility and effectivity of P-ISOMAP can be verified by experimental results very well.

ISOMAP算法对邻域大小敏感,而邻域大小却难以有效选取.本文根据二阶最小生成树不含有“短路”边的特性提出了能有效删除邻域图中的“短路”边因而对邻域大小不甚敏感的P-ISOMAP算法.由于避免了邻域大小难以有效选取的问题,该算法能更容易地对数据进行可视化,也获得了一定程度的拓扑稳定性和鲁棒性.实验结果很好地验证了该算法的有效性.
