Análise comparativa de técnicas avançadas de agrupamento
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ciência da Computação - PPGCC-SoCâmpus Sorocaba, 2016-01-29)
The goal of this study is to investigate the characteristics of the new data clustering approaches, carrying out a comparative study of clustering techniques that combine or select multiple solutions, analyzing these latest ...
PVis - Partitions’ Visualizer: extracting knowledge by visualizing a collection of partitions
(IEEE Computational Intelligence SocietyChinese Academy of SciencesNational Natural Science Foundation of ChinaBeijing, 2014-07)
Recent advances in cluster analysis highlight the importance of finding multiple meaningful partitions and point out to the need for approaches to evaluate them. They also suggest that the evaluation should consider knowledge ...
Full predictivistic modeling of stock market data: Application to change point problems
(ELSEVIER SCIENCE BV, 2007)
In change point problems in general we should answer three questions: how many changes are there? Where are they? And, what is the distribution of the data within the blocks? In this paper, we develop a new full predictivistic ...
Avaliação do impacto da seleção de partições base em ensemble multiobjetivo
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ciência da Computação - PPGCC-SoCâmpus Sorocaba, 2018-02-23)
Unsupervised data clustering is not a trivial process, as no previous knowledge is available
and real data is often complex and multi-faceted. To make matters worse, traditionally,
clustering aims to describe the data ...
Graph partitioning-based clustering for the planning of distribution network topology using spatial- temporal load forecasting
(2021-09-15)
Planning the expansion and the new topology of distribution networks requires knowing the location and characterization of the load as well as its future growth. Spatial load forecasting is a key tool in this task, providing ...
A Gibbs sampling scheme to the product partition model: an application to change-point problems
(PERGAMON-ELSEVIER SCIENCE LTD, 2003)
This paper extends previous results for the classical product partition model applied to the identification of multiple change points in the means and variances of time series. Prior distributions for these two parameters ...
Coexistence mechanisms at multiple scales in mosquito assemblages
(BioMed Central, 2014-11-11)
Abstract
Background
Species coexistence in mosquito assemblages may depend on mechanisms related to interspecific resource partitioning occurring at multiple scales. In the ...
Sediment quality in a metal-contaminated tropical bay assessed with a multiple lines of evidence approach
(Elsevier B.V., 2017-09-01)
A sediment quality assessment was performed near to the main industrial source of metal contamination in Sepetiba Bay, Brazil, which represents one of the worst cases of trace metal contamination reported for coastal areas. ...
