The current presentation describes advances to formalize the network training, calibrate the component alerting algorithms and decision nodes together, and implement a validation strategy. A cross-validation strategy produced consistent threshold combinations yielding 88% sensitivity from reported events, a 10-15% improvement over the original demonstration module.}, number={1}, journal={Online Journal of Public Health Informatics}, author={Burkom, Howard and Elbert, Yevgeniy and Ramac-Thomas, Liane and Cuellar, Christopher}, year={2014}, month={Mar.} }
