Smaller but smarter crowd
|
There is empirical evidence that the data collected from a potentially smaller but smarter crowd can benefit a machine learning system. For instance, the Good Judgment Open project reported the existence of a small subset of super-forecasters. A general difficulty of learning and identifying a smarter crowd is the lack of ground-truth, be either in an objective or a subjective manner. I rigorously study this question and quantify the best sub-crowd for performing certain tasks. |

My favorite wisdom of crowd quotes
“If small groups are included in the decision-making process, then they should be allowed to make decisions. If an organization sets up teams and then uses them for purely advisory purposes, it loses the true advantage that a team has: namely, collective wisdom.” -- James Surowiecki, The Wisdom of Crowds
"The wisdom of crowds works when the crowd is choosing the price of an ox, when there's a single numeric average. But if it's a design or something that matters, the decision is made by committee, and that's crap. You want people and groups who are able to think thoughts before they share." Jaron Lanier
