- 01-2019: In recent work entitled The Oracle of DLPhi (jointly with the participants of the Oberwolfach Seminar: Mathematics of Deep Learning) we show the groundbreaking result that deep neural networks are capable of predicting anything as long as they are presented with a sufficient amount of training data (in this case uncountably many training samples) and as long as one trusts the Axiom of Choice. This manuscript has mostly humouristic value. However, while the main theorem is based on a dubious application of the axiom of choice, it is a correct mathematical statement. Therefore, this manuscript at least highlights
the dangers of applying mathematical theory to real-world applications blindly.
