Quality-Guaranteed and Cost-Effective Population Health Profiling: A Deep Active Learning Approach

Abstract

Reliability and cost are two primary consideration for profiling population-scale prevalence (PPP) of multiple None Communicable Diseases (NCDs). In this paper, we exploit intra-disease and inter-disease correlation in different traditionally-sensed-areas (TS-A) to reduce the required number of the profiling task allocated without compromising the data reliability. Specifically, we propose a novel approach called Compressive Population Health TS-A Selection (CPH-TS), which blends the state-of-the-art profile inference, data augmentation and active learning in a unified deep learning framework. It can actively select a minimum number of TS-A regions for profiling task allocation in each profiling cycle, while deducting of the missing data of the unprofiled regions with a probabilistic guarantee of reliability. We evaluate our approach on real-world prevalence datasets of London, which shows the effectiveness of CPH-TS. In general, CPH-TS assigned 11.1-27.3% fewer tasks than baselines, assigning tasks to only 34.7% of the sub-regions while the profiling error below 5% for 95% of the cycles.
