Summary excerpt: Computer-coded verbal autopsy (CCVA) algorithms predict cause of death from high- dimensional family questionnaire data (verbal autopsy) of a deceased individual, which are then aggregated to generate national and regional estimates of cause-specific mortality fractions. These estimates may be inaccurate if CCVA is trained on non-local training data different from the local population of interest.

Abstract excerpt: Quantification learning is the task of prevalence estimation for a test population using predictions from a classifier trained on a differen population. Commonly used quantification methods either assume perfect sensitivity and specificity of the classifier, or use the training data to both train the classifier and also estimate its missclassification rates… We proposed a generalized Bayesian quantification learning (GBQL) approach that uses the entire compositional predictions from probabilistic classifiers and allows for uncertainty in true class labeled test data.
