Major element oxides, obtained by x-ray fluorescence and atomic absorption spectrophotometry, and trace element concentrations, obtained by sequential instrumental neutron activation analyses, enable classifications of normal basalts, divergent basalts, Mount Washington (MW) and North Sister (NS) type ...

has proved to be of a great importance and significance in order to trace and reconstruct the development of a scientific discipline and its methodology, related in particular to the establishment of geological theories, paleontological classifications, institutional role of palaeontology (e.g. Rudwick ...

The remaining parts of this paper are organized as follows. Section 2 presents our proposed network for HSI classifications. Section 3 first illustrates experimental datasets and the network configuration, and then shows experimental results and analyses. We summarize some conclusions in Section 4. 2....
Calculating information entropy in classification Suppose S be the number of samples in training sets and there is m classifications of samples Ci (i=1, 2, …, m). Si is the number of samples in Classification Ci. The computational formula is as follows: m I (S1, S2 ,, Sm )...
