Figure 4. Systematic performance evaluation of the SRO morphological classification model. (A) Visualization of representative classification results from the independent test set; (B) Multiclass CM for classification accuracy assessment; (C) ROC curves with corresponding AUC values across four morphological categories. SRO: SrRuO₃; CM: confusion matrix; ROC: receiver operating characteristic; AUC: area under the curve; TPR: true positive rates; FPR: false positive rates.
