  1. When I teach ML to clinicians, I emphasize that they shouldn't throw their knowledge out the window in favor of variable selection methods. Their knowledge is extremely valuable input to the model; it can be incorporated in many ways.

      The first is the form of Bayesian Priors - encoding their beliefs as a starting point to analysis. However, the underused way to incorporate knowledge is through feature engineering; knowing how something was measured helps you understand if it's useful.

        I try to encourage this kind of collaboration, but oftentimes I work with people who only want an answer. I feel like such collaboration is pretty shallow; if the subject matter expert is engaged, the analysis is much more meaningful.

          It's encouraging these sorts of relationships with your collaborators that are part of analyst's soft skills toolkit. I'd love to hear how others are teaching this.

            We did this in our Analytics course by pairing clinicians with bioinformaticists for the final project; but also by cultivating an atmosphere of psychological safety.
