• Title: Towards Sustainable Census Independent Population Estimation in Mozambique
• Authors: Isaac Neal, Sohan Seth, Gary Watmough, Mamadou Saliou Diallo
• Abstract summary: We use census-independent approaches to estimate population in two pilot districts in Mozambique. To encourage sustainability, we assess the feasibility of using publicly available datasets to estimate population. We observe that population predictions improve when using footprint area estimated with this approach versus only publicly available features.

• Abstract: Reliable and frequent population estimation is key for making policies around vaccination and planning infrastructure delivery. Since censuses lack the spatio-temporal resolution required for these tasks, census-independent approaches, using remote sensing and microcensus data, have become popular. We estimate intercensal population count in two pilot districts in Mozambique. To encourage sustainability, we assess the feasibility of using publicly available datasets to estimate population. We also explore transfer learning with existing annotated datasets for predicting building footprints, and training with additional `dot' annotations from regions of interest to enhance these estimations. We observe that population predictions improve when using footprint area estimated with this approach versus only publicly available features.

  We evaluate how deep learning change detection techniques can unravel temporal population dynamics short intervals. A ResNet encoder, pretrained on a population mapping task with Sentinel-2 MSI data, was incorporated into a Siamese network. The network was trained at the census level to accurately predict population change.

  Fine-grained population maps are needed in several domains, like urban planning, environmental monitoring, public health, and humanitarian operations. We present POMELO, a deep learning model that employs coarse census counts and open geodata to estimate fine-grained population maps with 100m ground sampling distance. In a series of experiments for several countries in sub-Saharan Africa, the maps produced with POMELOare in good agreement with the most detailed available reference counts.

  Census-independent population estimation approaches using alternative data sources have shown promise in providing frequent and reliable population estimates locally. We explore recent representation learning approaches, and assess the transferability of representations to population estimation in Mozambique. Using representation learning reduces required human supervision, since features are extracted automatically. We compare the resulting population estimates to existing population products from GRID3, Facebook (HRSL) and WorldPop.

  We address the problem of modeling constrained hospital resources in the midst of the COVID-19 pandemic. For broad applicability, we focus on the common yet challenging scenario where patient-level data for a region of interest are not available. We propose an aggregate count explicit-duration hidden Markov model, nicknamed the ACED-HMM, with an interpretable, compact parameterization.

• Uncertainty Estimation and Sample Selection for Crowd Counting [87.29137075538213]
  We present a method for image-based crowd counting that can predict a crowd density map together with the uncertainty values pertaining to the predicted density map. A key advantage of our method over existing crowd counting methods is its ability to quantify the uncertainty of its predictions. We show that our sample selection strategy drastically reduces the amount of labeled data needed to adapt a counting network trained on a source domain to the target domain.

  We present a new statistical downscaling approach to derive fine-scale estimates of key socioeconomic attributes. For each selected socioeconomic variable, a Random Forest model is trained on the source Census units and then used to generate fine-scale gridded predictions. As a case study, we apply this method to Census data in the United States, downscaling the selected socioeconomic variables available at the block group level, to a grid of 300 spatial resolution.
