Improving multivariate data streams clustering. Author(s): BONES, C. C.; ROMANI, L. A. S.; SOUSA, E. P. M. de Clustering data streams is an important task in data mining research. Recently, some algorithms have been proposed to cluster data streams as a whole, but just few of them deal with multivariate data... ... Repository: BDPA Publication year: 2016
Revisiting "privacy preserving clustering by data transformation". Author(s): OLIVEIRA, S. R. de M.; ZAÏANE, O. Preserving the privacy of individuals when data are shared for clustering is a complex problem. The challenge is how to protect the underlying data values subjected to clustering without jeopardizing... ... Repository: BDPA Publication year: 2010
Feature extraction of spatial panel data with autoencoders for clustering the Brazilian agricultural diversity. Author(s): SILVA, M. A. S. da; MATOS, L. N.; SANTOS, F. E. DE O.; DOMPIERI, M. H. G.; MOURA, F. R. DE ABSTRACT - Brazilian agricultural production presents a high degree of spatial diversity, which challenges designing territorial public policies to promote sustainable development. This article propos... ... Repository: BDPA Publication year: 2022
Evaluating clustering methods on topographic and hydrological features on lidar data at forest environment. Author(s): RODRIGUES, D. A.; VENDRUSCULO, L. G.; ZOLIN, C. A.; LOPES, T. R. The acquisition of high resolution geographic data through laser technology has recently being expanded due to the development of LiDAR (Light Detection and Ranging) system. This technology?s growth i... ... Repository: BDPA Publication year: 2017
Feature engineering vs. extraction: clustering Brazilian municipalities through spatial panel agricultural data via autoencoders. Author(s): SILVA, M. A. S. da; MATOS, L. N.; SANTOS, F. E. de O.; DOMPIERI, M. H. G.; MOURA, F. R. de This article compares the clustering of Brazilian municipalities according to their agricultural diversity using two approaches, one based on feature engineering and the other based on feature extract... ...

Evaluating a self-organizing map approach to cluster a Brazilian agricultural diversity spatial panel data. Author(s): SILVA, M. A. S. da; MATOS, L. N.; SANTOS, F. E. de O.; MAOURA, F. R. de; DOMPIERI, M. H. G. Repository: BDPA Publication year: 2021
Comparison between cluster methods using simultaneous analysis of qualitative and quantitative data in bananas. Author(s): LEDO, C. A. da S.; ROQUE, R. L.; AMORIM, T. B.; GONÇALVES, Z. S.; FERREIRA, C. F.; AMORIM, E. P. Understanding the genetic variability in germplasm banks is essential to genetic breeding programs. Usually quantification of the variability is carried out using quantitative and qualitative data sep... ... Repository: BDPA Publication year: 2014
Automatic segmentation of the self-organizing map to support territorial zoning. Author(s): BARRETO, P. V. DE A.; SILVA, M. A. S. da; MATOS, L. N.; MIRANDA JÚNIOR, G. F.; DOMPIERI, M. H. G.; MOURA, F. R. DE; RESENDE, F. K. S. ABSTRACT: This paper proposes an algorithm for analyzing clusters of thematic maps with ordinal categorical classes to support territorial zoning. The proposed method combines the Self-Organizing Map... ... Repository: BDPA Publication year: 2023
Tracking the Connection between Brazilian Agricultural Diversity and Native Vegetation Change by a Machine Learning Approach. Author(s): SILVA, M. A. S. da; MATOS, L. N.; SANTOS, F. E. DE O.; DOMPIERI, M. H. G.; MOURA, F. R. DE ABSTRACT - In Brazil, agribusiness has a considerable role in the country?s GDP. Because of this, the State needs territorial planning to minimize the impacts on natural resources, especially in the P... ... Repository: BDPA Publication year: 2022
Clustering approaches and ensembles applied in the delineation of management classes in precision agriculture. Author(s): SPERANZA, E. A.; CIFERRI, R. R.; CIFERRI, C. D. de A. Abstract. This paper describes an experiment performed using different approaches for spatial data clustering, aiming to assist the delineation of management classes in Precision Agriculture (PA). The... ...
