Gianluca Fiorelli says, “Whenever Google announces something as important as a new algorithm, I always try to hold off on writing about it immediately, to let the dust settle, digest the news and the posts that talk about it, investigate, and then, finally, draw conclusions.

I did so in the case of Hummingbird. I do it now for RankBrain.

In the case of RankBrain, this is even more correct, because — let’s be honest — we know next to nothing about how RankBrain works. The only things that Google has said publicly are in the video Bloomberg published and the few things unnamed Googlers told Danny Sullivan for his article, FAQ: All About The New Google RankBrain Algorithm.

Dissecting the sources

As I said before, the only direct source we have is the video interview published on Bloomberg.

So, let’s dissect that video and what Greg Corrado — senior research scientist at Google and one of the founding members and co-technical lead of Google’s large-scale deep neural networks project — said“.
