As a proof of principle, we focus on gene extraction for the (sodium) ion mobility in glasses of the Na2O-P2O5-AlF3-SO3 family. For these glasses, a highly consistent datasat including 56 individual samples with variable chemical composition is available from our lab, together with a range of physical and spectroscopic data [6-8]. In order to improve the accuracy of chemical composition data over previously available energy-dispersive X-ray spectroscopic results (EDX, [15]], all glasses were re-analyzed by fully quantitative wavelength-dispersive X-ray spectroscopy (WDX) using a JEOL JXA8800L microprobe analyzer. Generally, compared to standardless EDX the WDX technique provides improved energy resolution, detection limit more precise results, in particular, for the lighter elements such as F (the elemental composition obtained in this way and the previously reported ionic conductivity are the (X,Y) input in Figure ).
