AUC of the Histogram algorithm plotted over a 2 years horizon illustrating the large variations of the mean values in table 1 for all three datasets. The black curve is averaged over appliances, whereas the colored lines depict the individual appliances’ performance. Red: tumble dryer, blue: dishwasher, green: washing machine. Interruptions in the lines result from a lack of sufficient values to confidently assess an AUC value for certain validation periods
