- Repeat encounters vs unique encounters are available in their DHS DB but is CUI and requires DHS computer - It sounds like they know how many enter the US but that might be in the CUI DB. - They are using Socio-political data (e.g., OECPs) - They are using moving monthly averages as a feature because trends tend to be significantly longer than 1 month - They can't pick up the base causes for bumps (we should have better luck using news as a data source and causal analysis) - The DHS metric of interest was not known but they eventually settled on MAPE, which was similar to RMSE/actual value
