Occam's Razor. The term "Occam's Razor" comes from a misspelling of the name William of Ockham. Ockham was a brilliant theologian, philosopher, and logician in the medieval period. The idea is always to cut out extra unnecessary bits, hence the name "razor." An example will help illustrate this.
Called Ockam's razor (more commonly spelled Occam's razor), it advises you to seek the more economical solution: In layman's terms, the simplest explanation is usually the best one. Occam's razor is often stated as an injunction not to make more assumptions than you absolutely need.
1a : the quality of being careful with money or resources : thrift the necessity of wartime parsimony. b : the quality or state of being stingy The charity was surprised by the parsimony of some larger corporations.
Occam's Razor, put simply, states: “the simplest solution is almost always the best.” It's a problem-solving principle arguing that simplicity is better than complexity. Named after 14th-century logician and theologian William of Ockham, this theory has been helping many great thinkers for centuries.

Example: A man of considerable parsimony, Claude was known for lying about his age in order to receive senior discounts. Example: Rather than spending the money to take his car to the garage, Claude indulged his inner sense of parsimony and attempted the repairs himself.
In science, Occam's razor is used as a heuristic to guide scientists in developing theoretical models rather than as an arbiter between published models. As a logical principle, Occam's razor would demand that scientists accept the simplest possible theoretical explanation for existing data.
As we have seen, Ockham argues that there is no universal essence. There is therefore no basis for an intelligible species. Each object in the world is an absolute individual and that is how we perceive it at first.
Occam's razor (also known as the 'law of parsimony') is a philosophical tool for 'shaving off' unlikely explanations. Namesake William of Occam said the best explanation of any phenomenon is the one that makes the fewest assumptions.
“The molecular biologist Sidney Brenner recently invented a delicious play on Occam's Razor, introducing the new term Occam's Broom, to describe the process in which inconvenient facts are whisked under the rug by intellectually dishonest champions of one theory or another.
William of Occam QuotesIt is vain to do with more what can be done with fewer.
The view that simplicity is a virtue in scientific theories and that, other things being equal, simpler theories should be preferred to more complex ones has been widely advocated in the history of science and philosophy, and it remains widely held by modern scientists and philosophers of science.
Q: How does Occam's razor apply to machine learning? A: The use of Occam's razor dates back to William of Ockham in the 1200s – it's the idea that the simplest and most direct solution should be preferred, or that with different hypotheses, the simplest one or the one with fewest assumptions will be best applied.
In everyday use, the word "theory" often means an untested hunch, or a guess without supporting evidence. But for scientists, a theory has nearly the opposite meaning. A theory is a well-substantiated explanation of an aspect of the natural world that can incorporate laws, hypotheses and facts.
