This week, we will build our supervised ... many machine learning competitions, aggregating predictions from multiple tree models. This week you will start by learning about random forests and bagging ...

For example, if you want to automatically detect atrial fibrillation, a common type of irregular heart rhythm, you need to tell the machine-learning algorithm what atrial fibrillation looks like.

A new “periodic table for machine learning,” is reshaping how researchers explore AI, unlocking fresh pathways for discovery.
