Imputation of missing parts in UAV orthomosaics using PlanetScope and Sentinel-2 data: a case study in a grass-dominated área. Author(s): PEREIRA, F. R. da S.; REIS, A. A. dos; FREITAS, R. G.; OLIVEIRA, S. R. de M.; AMARAL, L. R. do; FIGUEIREDO, G. K. D. A.; ANTUNES, J. F. G.; LAMPARELLI, R. A. C.; MORO, E.; MAGALHÃES, P. S. G. In this study, we propose a methodological framework to impute missing parts of UAV orthomosaics using PlanetScope (PS) and Sentinel-2 (S2) data and the random forest (RF) algorithm of an integrated c... ...

Multiple imputation to fill in missing data in soil physico-hydricalproperties database. Author(s): OLIVEIRA, L. M. de; LIMA, H. V. de; RODRIGUES, S.; CARVALHO, E. J. M.; TORRES, L. C. Valores faltantes em banco de dados é um problema comum e quase inevitável. A imputação múltipla (IM) é ummétodo estatístico eficiente para estimar valores ausentes em um conjunto de dados incompleto.... ... Repository: BDPA Publication year: 2020
Model for multiple imputation to estimate daily rainfall data and filling of faults. Author(s): CARVALHO, J. R. P. de; MONTEIRO, J. E. B. de A.; NAKAI, A. M.; ASSAD, E. D. Modeling by multiple enchained imputation is an area of growing importance. However, its models and methods are frequently developed for specific applications. In this study the model for multiple imp... ... Repository: BDPA Publication year: 2017
Distribution of annual rainfall in homogeneous regions through data mining techniques in southern Brazil. Author(s): AVILA, A. M. H. de; FERREIRA JÚNIOR, D.; OLIVEIRA, S. R. M. This study aimed to transform time series of annual data of precipitation of Rio Grande do Sul in homogeneous precipitation regions through clustering techniques (data mining). Repository: BDPA Publication year: 2015
Open legacy soil survey data in Brazil: geospatial data quality and how to improve it. Author(s): SAMUEL-ROSA, A.; DALMOLIN, R. S. D.; MOURA-BRUNO, J. M.; TEIXEIRA, W. G.; FILIPPINI ALBA, J. M. Spatial soil data applications require sound geospatial data including coordinates and a coordinate reference system. However, when it comes to legacy soil data we frequently find them to be missing o... ... Repository: BDPA Publication year: 2020
A non-intrusive and reactive architecture to support real-time ETL processes in data warehousing environments. Author(s): VILELA, F. DE A.; TIMES, V. C.; BERNARDI, A. C. de C.; FREITAS, A. DE P.; CIFERRI, R. R. Nowadays, organizations are very interested to gather data for strategic decision-making. Data are disposable in operational sources, which are distributed, heterogeneous, and autonomous. These data a... ... Repository: BDPA Publication year: 2023
Different t-norms for DEA-fuzzy efficiency computations. Author(s): MEZA, L. A.; GOMES, E. G.; MELLO, J. C. C. B. S. de; BIONDI NETO, L. Repository: BDPA Publication year: 2009
A geometrical approach for fuzzy DEA frontiers. Author(s): BIONDI NETO, L.; MELLO, J. C. C. B. S. de; MEZA, L. A.; GOMES, E. G. Interval DEA frontiers are here used in situation where one input or output is subject to uncertainty in its measurement and is presented as an interval data. We built an efficient frontier without an... ... Repository: BDPA Publication year: 2009
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
