nelle slide del modulo su drift detection presentiamo diversi detector. Sarebbe bello avere un'immagine che illustra l'idea per ciascuno.

Ad esempio, la seguente immagine è un Illustration of the Page-Hinckley test to detect abrupt decreases of a signal. The solid red line shows the temporal evolution of some signal, the purple dotted line shows the computed result of the Page-Hinckley test that we use as observation to detect abrupt signal drops. At time t = 14 a drop of the signal occurs and is correctly detected (peak of purple dotted line). leading to m ω,t = M ω,t and thusˆmthusˆ thusˆm ω,t = 0.
