What does machine learning mean?
Making a computer work out a rule from examples instead of being given the rule. The examples are the data; the rule it finds is the model.
In a lesson
The camera image is 320 by 240 pixels, and each pixel is three numbers, red, green and blue. That is 230,400 numbers per frame. The blob and tag detectors in Module 4 boil that down to a handful: where the thing is and how big. Choosing a small set of numbers that still tells the situations apart is most of the work in machine learning. Those numbers are called features. In this module the features are the 16 level readings.
