That is, all nodes in a cluster should get the same election result.
All members in a cluster contribute to the generation of the common random value by generating and distributing their own random value.
The amendments introduced two new concepts - the SME cluster company, which a legal entity that has received a special certificate is eligible to become, and SME cluster members, which legal entities or individuals who received a special certificate and signed a contract with a cluster company are eligible to become.
Criteria for members of clusters of small and medium enterprises (SMEs) will be defined in Azerbaijan, Natig Hasanov, first deputy chairman of the board of the Agency for the Development of Small- and Medium-sized Businesses, told reporters, Trend reports.
ensemble approaches have several limitations: (1) they do not consider how to make use of prior knowledge given by experts, which is represented by pairwise constraints.
The commonly used seismicity partitioning methods include the K-Means cluster
, the hierarchical cluster
, the self-organizing maps (SOM), the fuzzy cluster
, the Gaussian mixture model (GMM), the density-based clustering algorithm (DBSCAN), and some other cluster
means, which have been listed in Table 1.
Partitioning methods  aim to organize data into a number of distinct clusters
, such that the total deviation of the data points from the cluster
centers is minimized.
It is an unsupervised organization of patterns into sets called clusters
; where a cluster
is collection of items which are similar to items in same clusters
and are different to the items belonging to other clusters
First, most existing schemes focus on 1-hop clustering; however, d-hop clustering is capable of providing improved and reliable performance for VANETs with better cluster
stability and lower cluster
(2) It is sensitive to selection of the initial cluster
Hard clustering approach , , clusters
the vehicles based on their locations and the vehicles in the boundary region are not precisely allocated to be in the appropriate cluster
