The Problem
Mental Health issues often go undiagnosed, sometimes leading to;
Suicide (Self Harm) •As many as 22 Veterans per day•With 80% of Suicidal Veterans are not in VA care•And while The Clay Hunt act provides more VA oversight & operational reform…not innovative action
Mass Shootings (Harm of others)•Often problems are detected•But the proper response is lacking•Action could be taken Before problems arise
Insider Threat (Theft of property)•With National Security implications•Multi-type: e.g. Germanwings Slide 2
Slide 3
Medical Context for Suicide
• The project was named in honor of Emile Durkheim, a founding sociologist whose 1897 publication of Suicide defined early language analysis for suicide explanations.
• Our team was comprised of a multidisciplinary team of artificial intelligence, & medical experts (Dartmouth & VA)
• Funded by DARPA from mid 2011- early 2013• Based on mathematics funded prior by IARPA • Delivered a data-powered mental health
screening system
Slide 5
The Durkheim Project
The math is like that of Moneyball (Lewis), where instead of statistics on your players, your looking at statistics on your consenting users. Big Data + Analytics provides a;•Greater risk assessment (over time) for individuals•Greater number of individuals that can be reached (e.g. rural communities)•Cost Reductions. As we can;
• Reach over 100,000 veterans with CURRENT systems
• Cut health care costs by isolating those at TRULY risk

Predictive Health Care
Slide 9
• Red terms are from Suicide Positive Cohort
• Yellow terms are from Psychiatric/Non-Suicidal Control
• Green terms are from Control Group
Example Features
• We developed linguistics-driven prediction models to estimate the risk of suicide.
• These models were generated from unstructured clinical notes
• From the clinical notes, we generated datasets of single keywords and multi-word phrases
• We were able to initially predict suicide with 65%* accuracy on a small dataset.
• * We have since reached 70%

Machine Learning (with VA)
Slide 10
Results
Dashboard• Provides real-time monitoring of patients by Clinical Professionals• Also enables a buddy-system• (Live at Dartmouth Hitchcock Medical Center)
Comparative Risk Monitoring• By Cohort• Daily Tracking (think Fitbit™ for mental health)
Slide 11
Dashboard Solution (for DARPA)
• Simplified user participation for consent, and privacy control
• Consent based access to online resources:
Slide 12
Opt-In Interface
• The Data is Secure/Protected• Specifically, the data persists at a medical center, behind a HIPAA
compliant firewall (e.g. Dartmouth Hitchcock Medical Center below)
• The highest professional security standards

Storage Layer
On July 2013, in conjunction with Facebook, Inc., we publically launched our project, with the aim of raising awareness, as well as direct recruiting of subjects. https://www.facebook.com/notes/us-military-on-facebook/durkheim-project-launch/472400246179609
… And since, we have been positively covered by NPR, NBC.com, Time.com, Fast Company, The Boston Globe, Daily Mail UK, Mashable, CIO, and CNN.com

Facebook Partnership
InterventionAutomated systems are coming online for potential patients and families seeking treatment, as well as passive intervention strategies (i.e. ‘safety plan’narratives).
Interventions that are designed to be timely and appropriate

Interventions Sequence
Germanwings Flight 9525
"Germanwings co-pilot Andreas Lubitz saw 41 doctors in five years;..." -ABC
"Germanwings Co-Pilot Andreas Lubitz Was Treated for Suicidal Tendencies" -WSJ
"Andreas Lubitz repeatedly set the same plane for an unauthorised descent earlier that day." -BBC
"He told former girlfriend he was planning an act so horrifying his name would be remembered forever." -Dailymail.co.uk
Should pilots be tested?Slide 4
Insider Threat: The Murder-Suicide Scenario
Why isn’t DARPA funding this further?The perception is that now that the science of the detection problem is proven, the next steps are 'too medical' for their agency mandate
Why isn’t NIH funding this?Heavy clinical/incremental medical studies focus & lack of dedicated technology funding for NIMH
Why isn’t VA funding this?The VA has scattered /uncoordinated attempts at similar. But the VA has a core outreach problem (well known statistics). And leading VA researchers are not (yet) taking Big Data approach
Why not Homeland Security?Pilot studies (of similar, not same technology) have been conducted. However, core policing engagement with suspects remains unchanged
Slide 19
Q&A
Suicide Risk:An opt-in risk assessment and intervention routing system ALREADY exists. We just need to deploy this at scale, through the responsible interface with medical practitioners and social workers.
Mass Shootings:Public surveillance and risk prediction, that ALSO protects personal rights IS possible through proper training. One that enables law enforcement and community preservation, where citizens are innocent before proven guilty.
Insider Threat: Agencies can incorporate motive models into their behavioral characterizations, rather than be blindsided.
Funding:No government agency has an existing mandate to rise to the challenge.

Takeaways
Fund Appropriations for comprehensive technology initiatives utilizing big data to detect mental health risks
• Research Programs• Pilot Projects
Fund training programs for professionals that can use technology for proper intervention, such as;
• Medical Staff • Police and Firefighters• Veterans and Social Workers
Public Awareness• Spotlight on mental health/suicide prevention• Congressional Hearings• Community involvement in District
