Unfortunately, when the overall data set is that huge, even half a percent of faulty data means a lot of flaws.
It is thus crucial to keep educating young scientists as patient free thinkers to avoid the coming of a "dark age" of science, lead by business-minded scientists, that are completely lost in an ocean of faulty data. .
They also mentioned that if the target class (faulty/non-faulty) is in the minority, accuracy is a poor measure as for example, a classifier could score 90%% accuracy on a dataset with 10%% faulty data, even if it predicts that all defective modules are defect free.
A further outcome of the analysis is the restructuring of the faulty data to a fault-free form through the filtering out of noise and bias.
Typical studies focus on recognition of faulty data with a given set of installed sensors on a wastewater treatment plant.
Since the generation of contribution plots requires no a priori information about the detected disturbance (e.g., historical faulty data), it is a popular fault isolation technique in Statistical Process Control (SPC).
And it subsequently turned out the absence of urgency among policy makers was largely a result of looking at faulty data".
