Grading Policy


  • There will be 3 to 4 Quizzes
  • Dates and Syllabus will be announced in Classroom

Review Project

  • Goal is to write a review on a specific topic of “Algorithms for Big Data”
  • The review should be comprehensive between 3000-4000 words. Do not write review only on one/two papers.
  • Review should be submitted with Single Column, double spacing pdf generated with LaTeX (use any standard template e.g., ACM, IEEE, Elsevier etc.)
You may work in a group of 2/3 person. Expectation of larger group will be higher.

Important Dates:

  • December 10, 2020: Groups Identified
  • December 25, 2020: Abstract Submission
  • January 20, 2021: Submission
  • January 30, 2021: First Report
  • February 5, 2021: Final Submission
Plagiarism tolerance is 7% from single source and 15% cumulative, anything more leads to lower or no marks at all.

Presentation + Viva

  • Between Jan 18-30, 2021
  • Exact dates will be announced latter
