Simon Mak | Integrating Science into Stats Models

Simon Mak | Integrating Science into Stats Models #statistics #science #ai

It’s a common dictum that statisticians need to incorporate domain knowledge into their modeling and the interpretation of their results. But how deeply can scientific principles be embedded into statistical models? Prof. Simon Mak (Duke University) is pushing this idea to the limit by integrating fundamental physics, physiology, and biology into both the models and model inference. This includes Simon’s joint work with Profs. David Dunson and Ruda Zhang (also of Duke University).

Scientific reasoning AND stats. What more could we ask for?

Enjoy!
