Teaching

• CS 499/549. Visual Analytics (Special Topic; Selected Topic in Data Science & Systems)
  Winter 2022
  This new course introduces "visual analytics", a field of study on combining interactive data visualization with automated analysis techniques for understanding, reasoning, and decision making on the basis of large and complex data. Students will learn how to design and build interactive data visualization interfaces for human users to effectively explore and analyze data and discover insights. There is no required pre-requisite, but web development experience (CS 290) is strongly recommended, because the programming assignments and group project include developing web-based data visualization interfaces using JavaScript and HTML/CSS.
• CS 565. Human-Computer Interaction
  Spring 2022, Spring 2021, and Spring 2020
  This course provides students with basic principles of and research methods in Human-Computer Interaction (HCI). Students will learn how to design and prototype user interfaces and interactive systems, based on the needs of users, and how to evaluate such interfaces and systems rigorously.
• CS 539. Data Visualization for ML (Selected Topic in AI)
  Fall 2020
  This course introduces advanced state-of-the-art research on interactive data visualization for machine learning. Students will learn how to design and develop interactive data visualization methods and tools that are interpretable to complex ML models (e.g., deep learning models), scalable to large data, and usable to a variety of users (e.g., ML researchers, practitioners like ML engineers and data scientists, non-expert learners).
