An Introduction to Machine Learning for Beginners

By Udit Agarwal


Machine Learning is a subfield of Artificial Intelligence that involves the development of algorithms and statistical models that enable computer systems to improve their performance on a specific task through experience. In other words, Machine Learning is a type of data analysis that automates analytical model building.

What do you mean by Machine Learning?

Arthur Samuel, a pioneer in Artificial Intelligence and computer gaming, introduced the term “Machine Learning” in 1959. He defined it as a field of study that enables computers to learn without explicit programming.

Machine Learning is an application of Artificial Intelligence (AI) that allows the software to learn from experience and improve at a task without explicit programming. For example, it can identify fruits based on properties like color, shape, and size.

What is the workability of Machine Learning?

To build a machine learning model is inspired by historical data, and then prediction algorithms are created to predict output for new input data. The accuracy of these models depends on the quality and quantity of input data. Having a large amount of data improves model accuracy.

Consider the following example: to solve a complex problem that requires predictions, instead of writing code, one can feed data to generic machine-learning algorithms. These algorithms enable the machine to develop logic and predict outputs. Machine learning has transformed problem-solving in both business and social contexts.
