- Abstract summary: We propose an inexpensive, scalable, and interpretable approach to predict key livelihood indicators from public crowd-sourced street-level imagery.
By comparing our results against ground data collected in nationally-representative household surveys, we demonstrate the performance of our approach in accurately predicting indicators of poverty, population, and health.

- Abstract: Major decisions from governments and other large organizations rely on
measurements of the populace's well-being, but making such measurements at a
broad scale is expensive and thus infrequent in much of the developing world.
We propose an inexpensive, scalable, and interpretable approach to predict key
livelihood indicators from public crowd-sourced street-level imagery. Such
imagery can be cheaply collected and more frequently updated compared to
traditional surveying methods, while containing plausibly relevant information
for a range of livelihood indicators. We propose two approaches to learn from
the street-level imagery: (1) a method that creates multi-household cluster
representations by detecting informative objects and (2) a graph-based approach
that captures the relationships between images. By visualizing what features
are important to a model and how they are used, we can help end-user
organizations understand the models and offer an alternate approach for index
estimation that uses cheaply obtained roadway features. By comparing our
results against ground data collected in nationally-representative household
surveys, we demonstrate the performance of our approach in accurately
predicting indicators of poverty, population, and health and its scalability by
testing in two different countries, India and Kenya. Our code is available at

Explainers [111.31448606885672]
Surrogate explainers are a popular post-hoc interpretability method to further understand how a model arrives at a prediction.
We propose two approaches to do so, namely (1) altering the method for sampling the local neighbourhood and (2) using perceptual metrics to convey some of the properties of the distribution of natural images.

This study marks the first attempt to cross-compare performances of popular state-of-the-art deep learning models in estimating population distribution from remote sensing images.
