Predicting Food Security Outcomes Using Convolutional Neural Networks (CNNs) for Satellite Tasking

13 Feb 2019  ·  Swetava Ganguli, Jared Dunnmon, Darren Hau ·

Obtaining reliable data describing local Food Security Metrics (FSM) at a granularity that is informative to policy-makers requires expensive and logistically difficult surveys, particularly in the developing world. We train a CNN on publicly available satellite data describing land cover classification and use both transfer learning and direct training to build a model for FSM prediction purely from satellite imagery data. We then propose efficient tasking algorithms for high resolution satellite assets via transfer learning, Markovian search algorithms, and Bayesian networks.
