What is RainBrain Algorithm ?

[GeethaN]

RankBrain is a machine learning algorithm that sorts the search results by understanding search queries and measuring the level engagement of users with the results. Nowadays, we know that RankBrain optimization is the third most important ranking signal.

RankBrain is a machine learning algorithm that sorts the search results by understanding search queries and measuring the level engagement of users with the results. ... The machine learning algorithm works something like this: It's not based on the hand-coded algorithm used in the past by Google developers and testers.

The RankBrain is an AI (Artificial Intelligence) program built to help Google understand search queries. It helps Google to process search results and provide more relevant search results for users. It embeds a wide range of written languages into mathematical entities, named vectors, that the machine can understand. If RankBrain faces a sentence that it does not know, it can guess the meaning with similar sentences or words and filter the result accordingly, making it more accurate for the new tries.

RankBrain is a machine learning-based search engine algorithm, the use of which was confirmed by Google on 26 October 2015. ... Therefore, RankBrain attempts to guess what people mean and records the results, which adapts the results to provide better user satisfaction.

Enough answers are given, I think @admin should close the thread now!!

RankBrain uses machine learning to convert language into mathematical entities known as vectors. In layman terms, RankBrain translates words and phrases into mathematics, which allows it to better understand unique searches involving natural language or unique phrases. Where previously Google would be stumped by natural language or a unique search, RankBrain allows Google to better understand and return better results.

Corrado explains that a “very large fraction” of queries in Google are being interpreted by RankBrain. According to Corrado, about 15 percent of daily searches in Google are completely new to their system, and difficult to understand. Traditionally, machines have struggled to understand natural or “colloquial” language. RankBrain, a machine algorithm, is specifically designed to help with these types of queries.
