Prefer compositions to features in ML-Ops
Saturday, May 9, 2026
I had an interesting conversation with a colleague this week. He has built a model that predicts physiological stability for inpatients on intravenous antibiotics using a recent history of vital signs. The purpose is to identify patients who could be switched to oral antibiotics and therefore discharged sooner. I had also considered that the underlying physiological stability, or its inverse, was a common component of many acute hospital prediction problems. But I wonder if we could take this further when considering how we build features under the ML-Ops paradigm.
