dc.description.abstract | The paper introduces support vector machines
(SVM), a recent method in statistical learning theory, used to recognize
and classify soils according to their geographic origin. The classification
was performed based on activities of seven radionuclides determined by
gamma-ray spectrometry. The radionuclides of uranium and thorium
series (226Ra, 232Th, 235U, 238U) and 40K were used to differentiate
investigated areas based on geology, while cosmogenic beryllium (
7
Be)
and anthropogenic 137Cs were used to differentiate areas according to
their susceptibility to fallout. The performances of the proposed method
was compared to those of principal component analysis (PCA), linear
discriminant analysis (LDA), k-nearest neighbours (kNN), soft
independent modelling of class analogy (SIMCA) and artificial neural
networks (ANN) applied to the same dataset. | sr |
