What is machine learning?

Machine learning is an area of artificial intelligence and computer science that comprises supervised and unsupervised learning and includes the development of software and algorithms that can make predictions based on data.^{Footnote 1} Machine learning is utilized across various industries. In the field of data analytics, for example, machine learning is used to make predictions based on trends and insights from data.

A prime example of the application of machine learning is the autonomous vehicle. Sensors around the vehicle deliver thousands of data points which are analyzed and processed to move the vehicle toward its destination. Collective data from thousands of self-driving cars can be used to improve vehicle safety and prevent accidents.

There are many different career paths within the machine learning field that can lead to a fulfilling career. Machine learning online courses and machine learning certifications are two ways that individuals can develop the skills to compete for jobs in this field.
