On the Importance of Mathematical Models

Last month, our team won the DARPA Chikungunya Challenge. We were asked to predict the number of cases of Chikungunya observed in the Pan American Health Organization (PAHO) countries from the beginning of September 2014 till the end of February 2015. Our predictions were then scored against the actual numbers reported on the PAHO website. Points were also awarded for methodology, presentation,…
