Hierarchical clusters of vegetation types
In this paper, we examine possible sources of hierarchical (nested) structure in vegetation data. We then use the Minimum Message length principle to provide a rational means of comparing hierarchical and non-hierarchical clustering. The results indicate that, with the data used, a hierarchical solution was not as efficient as a nonhierarchical one. However, the hierarchical solution seems to p...
متن کاملGraph Clustering by Hierarchical Singular Value Decomposition with Selectable Range for Number of Clusters Members
Graphs have so many applications in real world problems. When we deal with huge volume of data, analyzing data is difficult or sometimes impossible. In big data problems, clustering data is a useful tool for data analysis. Singular value decomposition(SVD) is one of the best algorithms for clustering graph but we do not have any choice to select the number of clusters and the number of members ...
متن کاملRelationship between Soil Characteristics and Vegetation Types in Damghan
Relationships between soil factors and vegetation types in playa of Damghan was investigated. Six vegetationtypes including Artemisia.sieberi, Arundo. sp, Artemisia.sieberi-Peganum.harmala, Alhagi.cammelerom,Artemisia.sieberi-petropyron.sp, Tamarix.passerinoides-Halocnemum strobilaceum. One bare land was recognized inthe study area and the research was conducted within mentioned types. Canopy p...
متن کاملIdentifying Non-hierarchical Spatial Clusters
Investigating relationships in information is an important component of statistical and spatial analysis. Clustering techniques have proven to be effective in helping to find patterns or relationships which otherwise may not have been detected. One of the most popular partitioning based clustering approaches is k-means. In this paper we explore the application of the k-means approach to spatial...
متن کاملHierarchical Graphs , Graph Types , and
Currently existing graph grammar-based speciication languages have serious problems with supporting any kind of \speciication-in-the-large" activities. More precisely , they have deeciences with respect to modeling hierarchical data structures or specifying meta activities like manipulation of graph schemata. Furthermore, already proposed graph grammar module concepts are still too abstract to ...
