The Machine Learning Process Applied on Machine Learning Problems

Let’s review machine learning (ML) problems and the ML method of solving them. This first chapter has just these two objectives.

The ML problem

The kind of problems that require some patterns to be identified, such that those patterns do not work for only one instance of the problem, but generally work for the whole class of instances, are known as ML problems. Classification is one such ML problem. For example, we, as humans, do not memorize in a picture-perfect way what one specific spiral galaxy looks like. Instead, we identify some specific patterns which help us distinguish between spiral and other classes of galaxies, after looking at some shots of spiral galaxies.
