NudgeRank™: Digital Algorithmic Nudging for Personalized Health

Our research paper has been accepted at KDD 2024 – “NudgeRank™: Digital Algorithmic Nudging for Personalized Health”! 

In this paper, we introduce NudgeRank™, an innovative digital algorithmic nudging system designed to foster positive health behaviors on a population-wide scale. Utilizing a novel combination of Graph Neural Networks augmented with an extensible Knowledge Graph, this Recommender System is operational in production, delivering personalized and context-aware nudges to over 1.1 million care recipients daily.

Key highlights:

• Rigorous evaluation reveals statistically significant improvements in health outcomes
• 6.17% increase in daily steps
• 7.61% more exercise minutes
• 13.1% open rate compared to baseline of 4%

This enterprise deployment marks one of the largest AI-driven health behavior change initiatives, accommodating diverse health conditions and wearable devices. Download the full paper for more insights and detailed findings!
