With luck there will be many small packets of data for email or some data application. This would provide many frequent data points you could use to track detailed individual movements, say every 20 mins. If only voice calls and SMS/text are used, then there will be fewer points of data to work with and you will likely need many thousands of individuals (rather than 500) to build detailed insight.<br /><br />What you describe is definitely a good idea, and not dissimilar to marketing analytics the telco might do themselves.<br /><br />Cheers<br /><br />Tim <br />http://timmanns.blogspot.com/Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-6141980.post-77746714466378788102011-06-03T15:55:57.154-05:002011-06-03T15:55:57.154-05:00I have your point but I still don't think it i...I have your point but I still don't think it is a major undertaking by the standards of the computing power that is available. The Netflix prize had 100 million data points and people were routinely solving the system to a reasonable accuracy (not the winners of course) in less than a day on a single commodity desk top machine. If you throw a typical university cluster with 100 machines at the problem we are talking about a problem that might take minutes to hours. If you could use the spare capacity at a Google data center it might take only seconds. <br /><br />From a North American perspective, an additional source of data about the movements of individuals would be credit card data and there would be no reason why credit card and telephone data could not be combined to map movements. So far as privacy goes - asking the sick people to consent to disclosure should take care of that.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-6141980.post-72697850837779529572011-06-03T02:46:55.285-05:002011-06-03T02:46:55.285-05:00Fixed. thanks Anonymous,Fixed. thanks Anonymous,Igorhttps://www.blogger.com/profile/17474880327699002140noreply@blogger.comtag:blogger.com,1999:blog-6141980.post-58122715003698516292011-06-03T02:39:24.722-05:002011-06-03T02:39:24.722-05:00nonnative english speakers might miss the fact you...nonnative english speakers might miss the fact you wrote "as fart as we know" haha good one!Anonymousnoreply@blogger.com
