Human beings rely on summarizing and visualizing data to make informed decisions. The number and volume of data continues to increase at exponential rates, and new user-facing systems and modalities are needed to handle the scale and heterogeneity of future data. This course surveys the landscape interactive data exploration systems along several axes.

Course Expectations

What This Class is NOT

What I expect from You


For assignments, you allowed 5 penalty free late days to use throughout the semester. One late day equals one 24 hour period after the due date of the assignment. Once you have used your late days, there will be a 20% penalty for each day an assignment is late. You do not need to explictly declare the use of late days; we will assign them to you in a way that is optimal for your grade when different assignments are worth different numbers of points. Late days may not be used for the final project.

Project (semester long)

You will pursue a semester long research project related to this course. The project is a significant part of the course grade.

Paper Questions (every class)

You are expected to answer the short questions associated with the readings every course. The class reviews must be submitted by 9PM the day before class.

Add your answers to the appropriate lecture’s wiki page

Paper Presentations

You have the option to present as a group (1-2 people) for one lecture on a topic/paper of your choice (within reason). The paper(s) you select can be from the list given below. You are also free to list a paper of your choice as long as it matches the themes of the class. This list must be submitted by midnight Feb 1.

You will be asked to complete three milestones for the presentation. Their purpose is to ensure high presentation quality—it is also a good excuse to practice your presentation skills and get feedback:

  1. 2 weeks before your presentation: present to Professor Wu
  2. 1 week before your presentation: present to two or more classmates and get feedback. The classmates should send me their notes from the presentation.
  3. Day of class: give awesome presentation

Submit the teammates and papers to present
