Machine Learning Algorithms - Second Edition

Only learning matters

What does learning exactly mean? Simply, we can say that learning is the ability to change according to external stimuli and remember most of our previous experiences. So, machine learning is an engineering approach that gives maximum importance to every technique that increases or improves the propensity for changing adaptively. A mechanical watch, for example, is an extraordinary artifact, but its structure obeys stationary laws and becomes useless if something external is changed. This ability is peculiar to animals and, in particular, to human beings; according to Darwin’s theory, it's also a key success factor for the survival and evolution of all species. Machines, even if they don't evolve autonomously, seem to ...
