It seems that from the first day I used a computer, I've wanted it to suggest I do something based on what I've done already. Whether it be click a button, change a setting, or open something, it seems that some actions could easily be guessed and suggested.<p>Is this pie in the sky or something that seems feasible and useful to the you guys? I know HN has some of the most brilliant people responding to questions and feel that someone has to have thought about this or know of a current project or why there isn't one.
If I'm understanding your question correctly, (applications of machine learning) there are plenty of examples of this.<p>See google search suggestions, facebook's news stream, google ad suggestions, last.fm and pandora's music suggestions, etc.<p>Read this <a href="http://en.wikipedia.org/wiki/Machine_learning" rel="nofollow">http://en.wikipedia.org/wiki/Machine_learning</a>, and you too can know as much about machine learning as I do!<p>(edit): actually if you read the wiki article you will know an infinite amount more about machine learning than me.
Seems like online shopping's suggested items (such as shopping on Amazon) would fit the bill, or maybe the recently opened menus common on many programs provide suggested actions (even context-specific menu options). Am I misunderstanding your question?
