Wide & deep learning for predicting relative mineral compositions of sediment cores solely based on XRF scans, a case study from Pleistocene Paleolake Olduvai, Tanzania
《Artificial Intelligence in Geosciences》2024年第1期244-256,共13页Gayantha R.L.Kodikara Lindsay J.McHenry Ian G.Stanistreet Harald Stollhofen Jackson K.Njau Nicholas Toth Kathy Schick 
supported by the National Science Foundation (BCS grant#1623884 to Njau and McHenry);Computational work was also supported by NASA SSW grant NNH20ZDA001N.
This study develops a method to use deep learning models to predict the mineral assemblages and their relative abundances in paleolake cores using high-resolution XRF core scan elemental data and X-ray diffraction(XRD...
