What is Machine Learning?
The word ‘Machine’ in Machine Learning means computer, as you would expect. So how does a machine learn?
Given data, we can do all kind of magic with statistics: so can computer algorithms.
These algorithms can solve problems including prediction, classification and clustering. A machine learning algorithm will learn from new data.
There are two types of learning: supervised learning and unsupervised learning.. Say what?
Let’s suppose we have consumer data. I tell the computer: these customers have a high income, those customers have median income. The training phase.
Then we can ask this computer:
With unsupervised learning algorithms, you have no idea. You give the data to the computer and expect answers. Surprisingly, these work rather well.
