Motivation for developing spatio-temporal network and ensemble approaches. a Heatmap of pairwise %ILI correlations between all states in the study over the period September 30, 2012 to May 14, 2017. Five clusters of intercorrelated states are denoted by black boxes. b Geographic distribution of the five identified clusters. c RMSE improvement of Net over ARGO over the period September 28, 2014 to May 14, 2017. The improvement of Net is here defined as the inverse RMSE ratio of Net and ARGO, so values above 1 indicate improvement. d RMSE improvement of ARGONet over ARGO over the same period
