TED-Ed: Inside OKCupid: The math of online dating - Christian Rudder

The video explains the development and function of OkCupid's matching algorithm. It begins with an introduction to algorithms and their importance in computing. The video then details how OkCupid collects user data through questions to feed into the algorithm. A practical example is provided to illustrate how the algorithm calculates match percentages using a geometric mean. The video concludes by emphasizing the significance of algorithms in modern technology.

What is the primary purpose of OkCupid's matching algorithm?

Explain the significance of the phrase 'step-by-step way to solve a problem' in the context of algorithms.

How does OkCupid gather data from users for its algorithm?

How does OkCupid ensure that the questions asked are relevant to the matching process?

What are the three key pieces of information that OkCupid's algorithm uses for each question?

Describe how the algorithm calculates the match percentage between two users.

What is the geometric mean, and why is it used in the context of the matching algorithm?
