ML in Python: Decision Trees with Pandas

Doctors love decision trees, computer scientists love recursion, so maybe that’s why decision trees have been coming up so much in the Artificial Intelligence for Health Metricians class I’m teaching this quarter. We’ve been very sklearn-focused in our labs so far, but I thought my students might like to see how to build their own decision tree learner from scratch. So I put together this little notebook for them. Unfortunately, it is a little too complicated to make them do it themselves in a quarter-long class with no prerequisites on programming.
