Indeed, if ANN's were good at analyzing stochastic datasets, we'd have a lot of very wealthy AI students wandering about...<br /><br />ANN's are a tool - but they aren't as accurate as they are reputed to be. I can't help but think their 80% to 90% accuracy might not get much better. Besides, ANN's get <i>really</i> complex, really fast; those guys dealt with a reasonably small system, and an obviously reasonably-sized dataset. (I did have some concerns about their ANN architecture, though. I don't think it could model unusual situations very well.) <br /><br />Anyway - mix in some mapreduce with a distributed ANN (it would have to have a fairly complex architecture; I'd guess a multi-dimensional array of hidden nodes* would be needed) and it could shorten the time needed for modeling complex, stochastic, phenomena.<br /><br />Neat article, though. After a hiatus of nigh on a decade, I've recently rekindled my interest in ANN's, so this was really interesting to read. Thanks for sharing! :-)<br /><br />Carolyn Ann<br /><br />* I once built such a beast. It was a long time ago, and the software I used just about melted with the complexity of the ANN. I remember the vendor going pale when I described what I'd tried...Anonymoushttps://www.blogger.com/profile/00333372966116029977noreply@blogger.com
