Artificial Intelligence-based Decision Support Systems for Precision and Digital Health

Precision health, increasingly supported by digital technologies, is a domain of research that broadens the paradigm of precision medicine, advancing everyday healthcare. This vision goes hand in hand with the groundbreaking advent of artificial …

Reinforcement learning for sequential decision making in population research

Reinforcement learning (RL) algorithms have been long recognized as powerful tools for optimal sequential decision making. The framework is concerned with a decision maker, the agent, that learns how to behave in an unknown environment by making …

Microrandomized Trials: Developing Just-in-Time Adaptive Interventions for Better Public Health

Just-in-time adaptive interventions (JITAIs) represent an intervention design that adapts the provision and type of support over time to an individual’s changing status and contexts, intending to deliver the right support on the right occasion. As a …

Dynamic Treatment Regimes for Optimizing Healthcare

The study of evidence-based dynamic treatment regimes (DTRs) comprises an important line of methodological research within the domain of personalized medicine, a medical paradigm that transitions from the one-size-fits-all ideology. In this chapter …

Daily Motivational Text Messages to Promote Physical Activity in University Students: Results From a Microrandomized Trial

Low physical activity is an important risk factor for common physical and mental disorders. Physical activity interventions delivered via smartphones can help users maintain and increase physical activity, but outcomes have been mixed. Here we …

Adaptive learning algorithms to optimize mobile applications for behavioral health: guidelines for design decisions

Providing behavioral health interventions via smartphones allows these interventions to be adapted to the changing behavior, preferences, and needs of individuals. This can be achieved through reinforcement learning (RL), a sub-area of machine …
