One important idea for the multi-class classification problem is to combine binary classifiers (base classifiers), which is summarized as error correcting output codes (ECOC), and the generalized Bradley-Terry (GBT) model gives a method to estimate the multi-class probability. In this memo, we review the multi-class problem with the GBT model and discuss two issues. First, a new estimation algo...

A spectral decomposition method has been implemented to identify and quantify isotopic source terms in high-resolution gamma-ray spectroscopy static geometry shielding scenarios. Monte Carlo simulations were used build the response matrix of a shielded high-purity germanium detector monitoring an effluent stream with Marinelli configuration. The technique was applied series calibration spectra ...
