Mobile health (mHealth) technologies have transformed the mode and quality of clinical research. Wearable sensors and mobile phones provide real-time data streams that support automated clinical decision making, allowing researchers and clinicians to provide ecological and in-the-moment support to individuals in need. Mobile health technologies are used across various health applications such as improving HIV medication adherence, increasing activity levels, and reinforcing abstinence in addictions, among others. The development of mobile health technologies, however, has progressed at a faster pace than the science and methodology to evaluate their validity and efficacy.
Current mHealth technologies are limited in their ability to understand how adverse health behaviors develop, how to predict them, and how to encourage healthy behaviors. In order for mHealth to progress and have expanded impact, the field needs to facilitate collaboration among machine learning researchers, statisticians, mobile sensing researchers, human-computer interaction researchers, and clinicians. Techniques from multiple fields must be brought to bear on the substantive problems facing this interdisciplinary field: experimental design, causal inference, multi-modal complex data analytics, representation learning, reinforcement learning, deep learning, transfer learning, data visualization, and clinical integration.
This workshop will assemble researchers from the key areas in this interdisciplinary space necessary to better address the challenges currently facing the widespread use of mobile health technologies.
We invite contributions of up to 4-page extended abstracts (not counting references or optional supplementary materials) from a broad range of areas including but not limited to:
Machine Learning Methods for mHealth
Detection or prediction of adverse health behaviors
Predictions for wearable devices or other longitudinal data
Transfer learning in mHealth
Deep learning in mHealth
Decision making and reinforcement learning
Just-in-time adaptive interventions and sequential decision making
Application of (partially observable) Markov decision processes to mHealth
Experimental design for mobile health such as micro-randomized trials
Methods for effective communication of information to both users and clinicians
Application of mobile health in the real-time monitoring, diagnosis, and treatment of disease
Mobile health technology that uses sensor data, delivers interventions, or integrates with clinical practice
Patient-facing clinical applications to disease areas such as chronic disease and mental health
Clinical integration of information from wearable devices
Digital tools to integrate social determinants into patient and population health management
Extended abstracts should be submitted via CMT: https://cmt3.research.microsoft.com/ML4MH2020
Please use the standard NeurIPS style files (e.g. single column format): https://nips.cc/Conferences/2020/PaperInformation/StyleFiles. Review will be double blind, so please anonymize author identities along with clear references to an author's prior work.
Please note that the workshop is non-archival, so we welcome any submissions that may be under review at another conference or journal, as well as work that has been recently accepted elsewhere. We will request that accepted submissions be posted on this website before the start of the workshop, as long as that does not violate any rules regarding preprints for other venues.

Schedule
Schedule
All Times are listed in EST. The session will run from 10AM EST to 5:30PM EST

10:30 - 10:50 AM: Lee Hartsell
10:50 - 11:10 AM: Ally Salim Jr, "AI for Decision Support in Low Resource Areas"
Decision making is one of those extremely complex things that humans can do with relative ease most of the time. Healthcare providers do this hundreds and thousands of times per day, and do an amazing job given their various levels of expertise and the resources available to them. The Elsa Health Assistant is a set of tools and technologies that leverage advances in Artificial Intelligence and causal modeling to augment the capacity of lower cadre healthcare providers and support optimal and consistent decision making. Here we will share the challenges, failures and successes of the technologies and the team.

Afternoon Session: ML methods in Mobile Health
2:00 - 2:20 PM: Susan Murphy, "Assessing Personalization in Digital Health"
Reinforcement Learning provides an attractive suite of online learning methods for personalizing interventions in a Digital Health. However after an reinforcement learning algorithm has been run in a clinical study, how do we assess whether personalization occurred? We might find users for whom it appears that the algorithm has indeed learned in which contexts the user is more responsive to a particular intervention. But could this have happened completely by chance? We discuss some first approaches to addressing these questions.
2:20 - 2:40 PM: Tanzeem Choudhury, "Closing the sensing-to-intervention loop for behavioral health"
Mobile and ubiquitous computing research has led to new techniques for cheaply, accurately, and continuously collecting data on human behavior that include detailed measurements of physical activities, mobility, social interactions, mood, sleep quality and more. Continuous and unobtrusive sensing of behaviors has tremendous potential to support the lifelong management of mental health by: (1) acting as an early warning system to detect changes in mental well-being, (2) delivering personalized interventions to patients when and where they need them, and (3) significantly accelerating patient and physician understanding of changes in mental health in real-time. In this talk, I will give some examples of our work on turning sensor-enabled mobile devices into well-being monitors and instruments for administering real-time/real-place interventions.
2:40 - 3:00 PM: Tim Althoff, "Language-based Behavior and Interventions in Mobile Health"
Mobile health seeks to provide in-the-moment support to individuals in need. In this talk, I will discuss the challenges associated with behavior and interventions that are based on language. Language is high-dimensional and complex, but is a critical component of many health and support interactions. Specifically, I will describe how we can measure empathy in mental health peer support and how we can give feedback in order to empower peer supporters to increase expressed levels of empathy, using large-scale neural transformer architectures and reinforcement learning.
