A Deep Learning Approach for Population Estimation from Satellite Imagery

no code implementations30 Aug 2017 Caleb Robinson, Fred Hohman, Bistra Dilkina

We validate these models in two ways: quantitatively, by comparing our model's grid cell estimates aggregated at a county-level to several US Census county-level population projections, and qualitatively, by directly interpreting the model's predictions in terms of the satellite image inputs.
