Fig. 5: Kernel model calibration assessment.
From: Kernel learning assisted synthesis condition exploration for ternary spinel

The high uncertainty threshold was set at the 66th percentile (0.47) A Distribution of kernel model’s disagreements (errors) in the missing region by uncertainty level and class. B Probability vs uncertainty of all samples in the missing region. 100% of the multi-phase errors (FP) occur in the high uncertainty region, while most correct predictions (TP/TN) cluster in the low uncertainty regions with higher confidence (probabilities further from 0.5), demonstrating appropriate model calibration.
