This course pays particular attention to the ways in which researchers and data scientists can transform raw data into features (i.e., variables or predictors) used in various machine learning algorithms. We will provide strategies for using prior research, knowledge from practice, and logic to create features, as well as build and evaluate machine learning models. The process of building features will be discussed within a broader data-intensive research workflow using R.
What you'll learn
- How to transform and visualize data using R
- How to apply selected machine learning algorithms (e.g., logistic regression and decision trees) to regression and classification tasks in R
- Strategies for applying data-intensive research workflows for feature engineering and model building
Syllabus
Week 1: Finding features
Introduction to setting up a feature engineering workflow, which includes identifying problems of practice, relevant research, and brainstorming potential features.
Week 2: Data wrangling and visualization
Introduction to data wrangling, data visualization techniques, and structure discovery algorithms. Integrating theory, knowledge from practice, logic, and contextual factors into feature engineering will also be discussed.
Week 3: Modeling features
Introduction to using features within selected machine learning algorithms (e.g. logistic regression and decision tree) and the tradeoffs between interpretability and prediction.
Prerequisites
We highly recommend that you take the previous course in this series before beginning this course:
