所以,针对不规则数据分布的情况,有了Grid-Based and Density-Based算法。 1、Grid-Based Methods 将d维数据的每个维度划分为p个相等的区间,于是便得到了p^d个超立方体(如下图,二维数据得到的超立方体数为p^2),簇的搭建便会基于这些超立方体(为表述方便,下文均称其为block) 一个block被认为是密集的当且仅当其...

Clustering approach by fast search and find of density peaks and density-based spatial clustering of applications with noise, and so many other methods are reported to be capable of completing this task but are limited by their computation time of mutual distances between points or patterns. ...
Things You Probably Don’t Know About Grid-based Design “The grid is the most vivid manifestation of the will to order in graphic design. […] Units are the basic buildung block of a grid. They’re all uniform. Columns are the grouping of units that create the visual structure of the...
Coupling of particle and grid-based methods for debris flow simulation Although the particle method is effective for high resolution simulation, it has a significantly large calculation time. Therefore, a coupling method of pa... T Suzuki,N Hotta - 《Journal of the Japan Society of Erosion Contr...
The tracker uses particle-based methods to estimate the state of each grid cell and further classify them as dynamic or static. It uses a fixed number of persistent particles on the grid which defines the distribution of existing targets. It also uses a fixed number of particles to sample th...
Several DDM methods, including class-, region and grid-based, have appeared in the literature. This paper discusses grid-based DDM and presents a simulation platform developed and implemented for investigating the impact of grid-based filtering on performance. Our experimental results show that the ...
