area under the curve; AUC
Technical term used in mathematics and statistics, especially in contexts like ROC curves and integration.
The area under the ROC curve is one of the metrics for evaluating model performance.
Find the area under the curve of this function by integration.
積分 is the general mathematical operation of integration, while 曲線下面積 specifically refers to the resulting area under a curve.
ROC曲線 is the receiver operating characteristic curve; 曲線下面積 often appears in the context of evaluating its area.
Compound of 曲線 (curve), 下 (under), and 面積 (area). A direct calque of the English phrase 'area under the curve'.
