What is Machine Learning?

By on

Machine LearningMachine Learning (ML) “…explores the construction and study of learning algorithms.”

Furthermore, Machine Learning:

“…is about building programs with adaptable parameters that automatically adjust based on the data the programs receive. By adapting to previously seen data, the programs are able to improve their behavior. They also generalize data, meaning that the programs can perform functions on previously unseen datasets.” (Alejandro Correa Bahnsen)

According to Keith D. Foote:

“Machine Learning, at its most basic, is the practice of using algorithms to parse data, learn from it, and then make a determination or prediction about something in the world. So rather than hand-coding software routines with a specific set of instructions to accomplish a particular task, the machine is ‘trained’ using large amounts of data and algorithms that give it the ability to learn how to perform the task.”

Machine Learning combines the following:

  • Supervised Learning: Based on generalized rules; for example, separating SPAM from non-SPAM email.
  • Unsupervised Learning: Based on identifying hidden patterns (i.e., data mining).
  • Reinforcement Learning: Based on achieving a goal (e.g., beating an opponent at chess).

Machine Learning also includes programming machines to quickly learn from queries and adapt to changing data sets.

Other Definitions of Machine Learning Include:

  • Advanced algorithms “composed of many technologies (such as deep learning, neural networks and natural-language processing, guided by lessons from existing information).” (Gartner IT Glossary)
  • “Systems that update their knowledge base as a result of experience with data.” (Adrian Bowles)”
  • “A method of data analysis that automates analytical model building. “ (SAS)
  • “Algorithms that have built-in smarts to use available data to answer questions.” (Paramita Ghosh, DATAVERSITY®)
  • “Teaching computers to learn the same way we do, by interpreting data from the world around us, classifying it and learning from its successes and failures.” (Forbes)
  • “A sub-field of Artificial Intelligence or AI where machines take data and ‘learn’ for themselves.” (TechRepublic)
  • “The use of Artificial Intelligence (AI) for digital transformation.” (Harvard Business Review)
