Want to understand how machine learning impacts search? Learn how Google uses machine learning models and algorithms in search.

A classification technique called Learning to Rank (LTR) is used to perfect search results based on things like actual usage patterns. LTR isn’t an algorithm unto itself. The actual ranking is ...

This is a very powerful asymmetry: Anyone can notice a change in search results, but it’s extremely difficult to prove what caused it. That gives algorithm designers immense deniability.

Who owns the patent to Google's original search algorithm? To find the answer, we used Google's search algorithm, and the answer is Stanford University.
