Activation maps, embedding visualization, and comparison of SCIPE with microcensus data and footprint based estimates. (a) Tiles and their associated regression activation maps (RAMs) from fine-tuned Barlow Twins model. (b) Plot of t-SNE embeddings of representations from Barlow Twins for 75 random tiles and 75 microcensus tiles from Boane and Magude (main), with embeddings coloured by population (bottom left) and region (bottom right). (c) Predicted over observed plot over microcensus with prediction uncertainty. (d) Comparison between SCIPE estimates and building footprint based estimates on the microcensus grid tiles.
