Hierarchical grouping of non-connected structures

چکیده
We review multilevel hierarchies under the special aspect of their potential for abstraction and grouping. Motivated by claims to ’bridge the representational gap between image and model features’ and by the growing importance of topological properties we discuss several extensions to dual graph pyramids: structural simplification should preserve important topological properties and content abstraction could be guided by an external knowledge base.

Unsupervised On-line Learning of Decision Trees for Hierarchical Data Analysis
An adaptive on-line algorithm is proposed to estimate hierarchical data structures for non-stationary data sources. The approach is based on the principle of minimum cross entropy to derive a decision tree for data clustering and it employs a metalearning idea (learning to learn) to adapt to changes in data characteristics. Its efficiency is demonstrated by grouping non-stationary artifical dat...
متن کاملEfficiency of anchored and non-anchored ISSR markers to estimate genetic diversity among bread wheat cultivars
DNA markers are integrally connected to the success of molecular breeding and are fundamentally required by breeders to be able to, a. identify new gene sources in the available biodiversity, b. select parents in order to increase heterosis, c. decrease the number of backcross generations for gene introgression breeding programs, and d. carry out marker-assisted selection (MAS). The present re...

A Bluetooth ad-hoc network consists of Bluetooth devices interconnected into piconets and piconets interconnected into scatternets. The specification has not yet addressed the issue of algorithms for scatternet formation. Some algorithms have been proposed, but they are either synchronous, they work only with strongly connected topologies, or they are master-slave based and hierarchical of natu...

Hierarchical analysis is one of the prioritization methods of phenomena. This method provides comparison and use of expert people. In this research, the men-tioned method was applied in order to weight and prioritize valuation factors and indicators for applied science in primary school. The methodology of this research is descriptive survey. The statistical population is all experts (education...
