An Automatic Merge Technique to Improve the Clustering Quality Performed by LAMDA
(Institute of Electrical and Electronics Engineers Inc., 2020-01-01)
Clustering is a research challenge focused on discovering knowledge from data samples whose goal is to build good quality partitions. In this paper is proposed an approach based on LAMDA (Learning Algorithm for Multivariable ...
Density-based clustering validation
(Society for Industrial and Applied Mathematics - SIAMPhiladelphia, 2014-04)
One of the most challenging aspects of clustering is validation, which is the objective and quantitative assessment of clustering results. A number of different relative validity criteria have been proposed for the validation ...
Effects of leaf removal and cluster thinning on yield and quality of grapes (vitis vinifera l., riesling × silvaner) in corrales, boyaca (colombia)
(Universidad Nacional de Colombia, Facultad de Agronomía, Centro Editorial, 2011)
The vineyards that are located in the Colombian cool tropicalzone of Corrales (Boyaca department) offer grapes for the production of quality wines; to improve the crop we must know the adequate balance between the quantity ...
A clustering WSN routing protocol based on k-d tree algorithm
Clustering in wireless sensor networks has been widely discussed in the literature as a strategy to reduce power consumption. However, aspects such as cluster formation and cluster head (CH) node assignment strategies have ...
Data-Aware Scheduling Strategy for Scientific Workflow Applications in IaaS Cloud Computing
Scientific workflows benefit from the cloud computing paradigm, which offers access to virtual resources provisioned on pay-as-you-go and on-demand basis. Minimizing resources costs to meet user’s budget is very important ...
Different clusters in patients with chronic obstructive pulmonary disease (Copd): A two-center study in brazil
(2020-01-01)
Background: Chronic obstructive pulmonary disease (COPD) has a functional definition. However, differences in clinical characteristics and systemic manifestations make COPD a heterogeneous disease and some manifestations ...
Método para desenvolvimento de práticas de gestão integrada em clusters industriais
(Associação Brasileira de Engenharia de Produção, 2013)

Analysis of genetic association using hierarchical clustering and cluster validation indices
(Academic Press Inc Elsevier Science, 2017-10)
It is usually assumed that co-expressed genes suggest co-regulation in the underlying regulatory network. Determining sets of co-expressed genes is an important task, based on some criteria of similarity. This task is ...
