Machine Learning: A Brief Overview

Machine learning is no longer science fiction and has been around for decades in some specialized applications, such as optical character recognition (OCR).
The first mainstream ML application was the spam filter, which improved the lives of hundreds of millions of people in the 1990s.

What is Machine Learning?

Machine learning is the science (and art) of programming computers so they can learn from data.
It is the field of study that gives computers the ability to learn without being explicitly programmed.
A computer program is said to learn from experience E with respect to some task T and some performance measure P, if its performance on T, as measured by P, improves with experience E.

Key Concepts in Machine Learning

A training set consists of examples used to learn, such as spam emails and regular emails.
Each training example is called a training instance (or sample).
The part of a machine learning system that learns and makes predictions is called a model.
Examples of models include neural networks and random forests.

Evaluating Machine Learning Systems

The performance measure P needs to be defined, such as the ratio of correctly classified emails (accuracy).
Accuracy is often used in classification tasks.

What Does Not Constitute Machine Learning

Simply downloading a copy of all Wikipedia articles does not constitute machine learning, as it does not improve the computer's ability to perform a task.
