 # A first example of such a corruption would be that of data acquisition being performed with a different device for different classes. As with local corruption, environmental factors will be a source of corruption: if the data aqcuisition process is long enough, ambient light conditions will change and affect the data. Similarly, vibrations in the surrounding room may have an impact.

 # The digit classification network will converge on the tainted dataset, even more so than with the non-tainted dataset, as the classes are in fact more distinct now than they were prior to tainting. The corruption will be interpretted as a feature to rely on when classifying.

 # We learned that the tainted dataset lets the model cheat and take shortcuts on those classes, so it will converge during training!
