Edvan Cirino Silva scite author profile

Este trabalho compara o uso de um conjunto de validação separado e de validação cruzada amostra-a-amostra para guiar a seleção de variáveis no Algoritmo das Projeções Sucessivas (APS) para calibração multivariada. Análises de diesel e milho por espectrometria NIR são apresentadas. Uma interface gráfica do APS encontra-se disponível em www.ele.ita.br/ kawakami/spa/ This work compares the use of a separate validation set and leave-one-out cross-validation to guide the selection of variables in the Successive Projections Algorithm (SPA) for multivariate calibration. Two case studies involving diesel and corn analysis by NIR spectrometry are presented. A graphical interface for SPA is available at www.ele.ita.br/~kawakami/spa/
