What is ensemble learning?

BEGIN ARTICLE PREVIEW: Ensemble methods combine several machine learning models to improve results This article is part of Demystifying AI, a series of posts that (try to) disambiguate the jargon and myths surrounding AI. The principle of “the wisdom of the crowd” shows that a large group of people with average knowledge on a topic can provide reliable answers to questions such as predicting quantities, spatial reasoning, and general knowledge. The aggregate results cancel out the noise and can often be superior to those of highly knowledgeable experts. The same rule can apply to artificial intelligence applications that rely on machine learning, the branch of AI that predicts outcomes based on mathematical models. In machine learning,
