A novel approach to Earth Observation (EO) data analysis, called Multi-Scale Representation Concatenation, is introduced in this paper. This method transforms single-scale EO-based causal inference algorithms into multi-scale ones, enabling better estimation of conditional average treatment effects (CATE). The authors benchmark the performance of their approach using Vision Transformer (ViT) models and Causal Forests (CFs) on both simulation studies and real-world data from two randomized controlled trials (RCTs) in Peru and Uganda. The results show that Multi-Scale Representation Concatenation improves the accuracy of deep learning models without requiring new architectures, potentially leading to meaningful policy benefits.

EO data is used in policy analysis to estimate conditional average treatment effects (CATE). However, it’s hard to decide how much information to include from satellite images. This paper introduces a way to make single-scale CATE estimation algorithms work with different amounts of image detail. They test this method using Vision Transformer models and Causal Forests on simulated data and real-world trials in Peru and Uganda.
