Reinforcement Learning for Healthcare
- 14:00 24th November 2020 ( Michaelmas Term 2020 )Online
Many health settings involve making a sequence of decisions (e.g. sequencing treatments for HIV to manage viral loads now and limit cross-resistance later). The number of decisions makes these settings challenging to explore with traditional clinical trials; it would be helpful to know what kinds of sequences are most promising to explore. Batch Reinforcement Learning (RL) aims to propose novel treatment policies based solely on existing data -- e.g. the longitudinal views of a patient via their health records. In this talk, I will discuss batch RL algorithms that we have developed and applied in the context of hypotension management in the ICU as well as managing HIV. I will also discuss the limitations of these methods and our work to move beyond fundamental statistical limitations by seeking and integrating different kinds of validation by domain experts.
