Re: Airbus completes testing of self flying jet

Most machine learning algorithms are glorified interpolation algorithms. As such, they perform well within the data (e.g., the flight conditions) used for the training, but how well they can extrapolate is usually a big question mark. Neural Networks are polynomial interpolation on steroids, "d...
