Fig. 4: Comparison of Equation FeO and TiO2 maps with CNN FeO and TiO2 maps.
From: Global chemical composition maps of oxide distributions on the Lunar surface

Difference maps between a Equation FeO and CNN FeO, b Equation TiO2 and CNN TiO2. The positive values represent higher FeO and TiO2 abundance for Equation FeO and TiO2. c Histogram of FeO difference. d Probability density function scatter plots of Equation FeO map and CNN FeO map. e Boxplot of FeO difference. f Histogram of TiO2 difference. g Probability density function scatter plots of Equation TiO2 map and CNN TiO2 map (TiO2 > 1 wt.%). h Boxplot of TiO2 difference.
