**Introduction to Machine Learning.**

**4.**

More and more interactions in our lives are being shaped by so-called artificial intelligences. These computer programs have grown in sophistication to the point where they can classify and respond to complicated enough inputs such that their reactions can seem to indicate intelligent decision-making. In almost every field of inquiry or work, we are being surrounded by clouds of enormous data sets, and it is getting impossible for any human to be able to parse through the data and identify either patterns or interesting exceptions. This three-week, project-based course aims to give non-science students a sense of what machine learners do, what kinds of machine learning tools are out there, and how to choose what type of tool to use to handle a range of problems.
