Bridging a Mental Health Crisis with Multi Armed Bandits

Talk Abstract:

The pandemic we are facing has brought with it another health care crisis: access to mental health care. Quartet Health is bridging the crisis using AI to personalize the patient journey across the United States.

At each step of the patient journey, machine learning is leveraged to identify a patient’s needs, and get them into adequate mental health care. Using data on healthcare provider history and patient preferences, we productionized models to deliver personalized health care to patients, while optimizing our overall mental health care network.

In this presentation, we will walk through the complexity of using health care data and present an algorithm that matches patients to mental health providers. We will begin by formulating this matching algorithm as a non-stationary, contextual multi armed bandit problem, and then follow its evolution into a linear programming solution. The talk will include background on MAB problems, theoretical bounds, empirical analysis and implementation details.

Date and Time:

The talk will be held on Tuesday, April 5th at 1:00PM PDT.
