Learning from Auto-complete in Google Search

Despite all the various scary and crazy things people find in Google Search’s auto-complete, more often than not I get one overwhelming message.

So last night, when I started a search with “[w s v] = svd(…

I’d not gotten very far when autocomplete said:

[w s v] = svd((repmat(sum(x.*x 1) size(x 1) 1).*x)*x’)

Which is completely Crazy! or not. i means many people got to the same point in Andrew Ng‘s machine learning lecture, saw the same example on a slide (a one line MATLAB code example) and

interestingly, one of the first hits was on StackOverflow (meaning programmers were talking about this) at

http://stackoverflow.com/questions/20414667/svd-implementation-of-cocktail-party-algorithm

So while others may be creeped out, my reaction remains:  “you are not alone” 🙂
