Let's make some models! Most of the modeling techniques you'll use, whether supervised or unsupervised, will fall under the umbrella of machine learning, but that's not all you need to know. Knowing some social science will go a long way when it comes to formulating your models appropriately, designing experiments to evaluate model performance, and understanding what conclusions you can make based on your results. Quantitative Social Science and Causal Inference with Observational Data will help you think these questions through.
