What is Machine Learning…?

Machine learning is the subfield of computer science, that provides computers the ability to automatically learn on their own and improve from their experiences without being explicitly programmed. Though it has been hidden in the recent past but still machine learning has become a basic pillar of IT. We are constantly being surrounded by several ML-based applications like search engines, anti-spam filters, credit card fraud detection system, etc etc. ML is the subset of Artificial Intelligence, which deals with structured and semi-structured data. To understand the concept behind ML, a precise overview of AI is necessary. When AI was coined first in 1955, it's aim was to make machines that are able to perform unique human-based tasks that require intelligence.
