Investigators discuss new findings in Machine Learning. According to news reporting originating from Palaiseau, France, by NewsRx correspondents, research stated, "Automatic identification and quantification of y -emitting radionuclides, taking into account spectral deformations due to y - interactions in radioactive source surroundings, is a challenging task in the nuclear field. In that context, this paper presents a Machine Learning approach based on autoencoder that can learn a model for the spectral signatures of y -emitters with variability." Our news editors obtained a quote from the research from the University of Paris Saclay, "Training and test datasets were obtained by means of simulated y -spectra computed with the Geant4 simulation code according to increasing material thicknesses (steel, lead). A novel hybrid unmixing algorithm combining a pretrained autoencoder is studied for joint estimation of spectral signatures and counting in the case of mixtures of four radionuclides (57Co, 60Co, 133Ba, 137Cs). The investigations were carried out to account for spectral deformations due to attenuation, Compton scattering and fluorescence at high and low statistics." According to the news editors, the research concluded: "This study demonstrates the validity of this novel hybrid approach combining Machine Learning and Maximum Likelihood for the automatic full - spectrum analysis of y -spectra."
