I remembered my senior project, we developed a decision tree to determine what network problem a user is facing, and eventually grow the decision tree while the user is using it more. Bing brings another kind of decision (while I don’t know how helpful it is yet), while doing search queries it also guesses what you want and how it can help you. I just saw this new personal decision engine, called Hunch. It tries to solve questions in your life, like should you get a degree in science, should you go to grad school, should I get married, etc, with a series of questions, and also based on personal questions you have answered in the past. I guess it is somehow like the decision tree we did before, but in a much larger scale. The engine doesn’t need to look at you and give you a general answer based on just the series of questions, but slowly categorize you to similiar people with similar profiles, and have different trees under these branches as well. The scary thing I guess, if this evolves, is to rely on these kind of “engines” to make personal life choices for you. I rather receive and believe in faith regardless of what I know, and listen to my mentors instead of some computer engine online. But it is clearly an interesting product.
