BDA 2018; final schedule(updated)

I have created a new list of resources, for specific projects types such as spatial analysis and Twitter analysis. It is the  heading on the Latest Handouts page at Special topics for individual papers. 

Summary of the last 2 weeks of the course:

  • Only nominal homework – readings and one figure.
  • Work on projects. Ask for help if desired.  No more interim reports are due.
  • R Certification: If you want R certification for the course, take a one-hour quiz and meet some other requirements.
  • Make an in-class presentation: two-person teams only.
  • Final paper due

Wednesday, May 30. Handling unbalanced data, and other useful techniques.
Reading: Chapter 5.5, also 5.3 and 5.4. These were assigned previously.
Nothing to be turned in

Saturday, June 2: No progress report is due.

Monday, June 4: A/B Testing and other emerging topics in  Big Data

  • Look up specific techniques for your project. Spatial data and GIS, Text processing, Crime, Graphics, or Twitter. One or more applies to every project. Special topics for individual papers. 
  •   Turn in: One careful plot from your project. Hard copy, with comments on it by hand. Format the plot carefully and clearly including scales, colors, definitions, etc. Please turn these in by hand in class. This is to encourage hand-writing of comments.  Circle and explain at least one interesting/important feature of your plot.
    • Include a caption. Captions in scientific papers are sometimes several sentences long.
    • The goal of the assignment is to help you focus intensively on one result of your project, and how to explain it visually. It does not have to be a data-mining result.
  • Reading,  “The A/B Test: Inside the Technology That’s Changing the Rules of Business” Wired Magazine, 04.25.12. https://www.wired.com/2012/04/ff_abtesting/all/
  • Visit an e-commerce website and think about how to improve it using A/B testing.

Wednesday, June 6: All two-person project teams will give 5 to 7 minute presentations. The goal is to fascinate, impress, and surprise your audience. Think of this as the “elevator pitch” for your project.

Friday, June 8  1pm or other times as agreed: Quiz for R Certification. The quiz emphasizes data manipulation in R, Selecting data subsets, creating new variables , rearranging and redefining data such as event logs. The other requirements for R certificates are completing your project using appropriate R programming, and attending 50% of TA tutorials.

Friday, June 8 midnight: Formal due date for final project papers.
All projects who request one receive an automatic extension until Wednesday.
Submit both hard copy and PDF files. Submit via Turnitin, on TritonEd.

June 11.   Wednesday, June 13. Deadline for  projects.

Special topics – for specific papers

The Big Data Analytics course introduces data mining with techniques and concepts that are broadly applicable. Individual topics and projects have specific techniques, needs, and resources. In keeping with the theme “Borrow and re-use, don’t invent anything yourself,” here are some resources that are especially suited to particular topics.

Don’t forget to try to site’s Search window  (usually near the upper right) to look up possible keywords. Many of these topics also have entire books about them, such as on Springerlink.

Other links:

Google folder for the course.  There you will find all datasets for the textbook,

The official textbook web site is http://www.dataminingbook.com/book/r-edition
Once you register, you can get these datasets, and the R Code. (It’s better to type the R Code by hand, the first time.)
