It's only 1/2 the area of the full circle. So this is going to be four pi over two, which is equal to two pi. All right let's do another one. So here we have the definite integral from negative two to one of f of x dx. Pause the video and see if you can figure that out. All right let's do it together.

AUCArea Under the Curve. ROC曲線を作成した時に、グラフの曲線より下の部分の面積をAUC（Area Under the Curve）と言う。. AUCは0から1までの値をとり、値が1に近いほど判別能が高いことを示す。. 判別能がランダムであるとき、AUC = 0.5となる。. エクセル統計 ROC曲線.
How to Determine the Area Under the Curve? Let us assume the curve y=f(x) and its ordinates at the x-axis be x=a and x=b. Now, we need to evaluate the area bounded by the given curve and the ordinates given by x=a and x=b. The area under the curve can be assumed to be made up of many vertical, extremely thin strips.
8 de jul. de 2020 · AUC(Area Under the Curve)とは. AUCとは、その名のとおり、ROC曲線の下のエリアだ。 前回描いたROC曲線で説明すると、この赤い斜線のエリアだ。 AUCが1に近いほど予測能・診断能が高いモデルとなる。
