Google search indeed uses deep learning since it is powered by Artificial Intelligence (AI) but that does not mean the Google Search Engine is an AI. Moreover, the search engine has always been driven by systems of algorithms that generate an answer to each query automatically. These systems of algorithms resulted in a set of definite rules. A group of engineers from Google could at any time change and redefine these rules. The company incorporated its search engine with deep learning hence these algorithms did not learn on their own.
For clarity, deep learning is basically a section of how Google Search functions. About 15 percent of Google’s daily inquiries are handled by RankBrain. RankBrain is the most popular machine learning tool that Google uses. This machine learning engine is capable of assessing the words and phrases that make up a search query and determining whether additional words and phrases have similar meanings.
Initially, Google’s algorithm was coded by hand before RandBrain was introduced. Query results were analyzed by a group of engineers who also ran tests to ensure quality results are produced. RankBrains is known for solving tricky problems that Google was facing when using traditional algorithms. There has been a reduction in manual labor since search engines are capable of teaching techniques on how to run predictions.
