Easily labelling hierarchical document clusters. Author(s): MOURA, M. F.; MACACINI, R. M.; REZENDE, S. O. One of the problems of automatic models that generate topic taxonomies is the process of creating the most significant term list that discriminates each document group. In this paper, a new method to... ... Repository: BDPA Publication year: 2008
Streamlined approaches for image classification using principal component analysis and hierarchical clustering of extrudates from coffee and sorghum blends. Author(s): HIDALGO CHÁVEZ, D. W.; SILVA, F. L. C. DA; PINTO, R. V.; CARVALHO, C. W. P. de; FREITAS-SILVA, O. This article describes simple methods to group images including principal component analysis (PCA) and hierarchical clustering of principal components (HCPC). Images of expanded and low expanded extru... ... Repository: BDPA Publication year: 2023
Wavelet analysis and hierarchical clustering of ofm phenotypic population's variations originated from southern america and europe and attempts of a first relation to molecular divergence.

Non-hierarchical clustering of cassava germoplasm based on quantitative traits. Author(s): OLIVEIRA, E. J. de; AUD, F. F.; MORALES, C. F. G.; SANTOS, V. da S.; KOTWISKI, F.; V. COSTA The knowledge of the phenotypic variation of cassava (Manihot esculenta Crantz) germplasm allows estimating the genetic variability to support the selection of contrasting genitors. Therefore, the aim... ... Repository: BDPA Publication year: 2014
