Machine learning can be introduced for a linear classification using a manual paper-and-pencil method with a triangle. Based on this, a corresponding program code can be created in just a few steps. The method is suitable for use in computer science lessons, but also in other subjects if a simple machine learning method is to be applied to suitable subject-specific didactic content.

The video (click image on the left) shows the sequence of the learning algorithms "Perzeptron" and "Adaline" for a student's data set. The two algorithms are executed one after the other.
