Introduction to Machine Learning

What is Machine Learning?

Wikipedia: Field of study that gives machines the ability to learn without being explicitly programmed.
Examples are:
* Google, ever wondered how google suggests you searches using google instant and how pages are ranked in such a manner?
* How facebook identifies your friend(s) in a photo and how gives you ads?
* How Gmail decides whether a certain message is a spam or not?
* How Quora feed is organized and in what order digest mails are sent in your inbox?

Why we need Machine Learning?

Because of large data. The organizations have data to analyze and make models, if the work is given to some human it would be inefficient and error-prone. While the same work, if given to a machine, can be easily done without errors(if the error is not programmed!).

Mainly there are two types of applications: Classification and Clustering.
I will be writing about these in future posts.
