Optimizing Provider Recruitment for Influenza Surveillance Networks
Figure 6
Google Flu Trends as a virtual ILINet provider.
When state-level Google Flu Trends is treated as a possible provider, submodular optimization choses it as the first (most informative) provider for the Texas ILINet, and results in a high performing network (pink line). Alone (black line), the Google Flu Trends provider performs as well as a traditional submodular optimized network (blue line) containing providers (intersection of black and purple lines) and outperforms the actual 2008 Texas ILINet (green dot).
