Fig. 4. (A) Rock classification prediction accuracy by individual AI model. Results of testing with image data of 30% of all subjects. The true label of the target image is on the left, and the label predicted by the model follows the rock name specified below. For example, the image predicted as basaltic andesite in the PPL learning model was basaltic andesite with 93.8% probability. (B) K-means clustered data histogram for the color that appears when each rock is observed with a polarized microscope.
