9 weeks · 2 milestones

Mining Massive Datasets (Mining of Massive Datasets (free book and lectures, mmds.org)), then one project of your own. Part of the Varsity Curriculum: Data Science.

Do the course work in public

4–7 weeks (5–10 hrs/week)

Take Mining Massive Datasets for free and do homework for MapReduce, similar items (min-hashing), link analysis (PageRank) and frequent itemsets, with your code. Keep everything in one public repo or notebook as you go. OSSU links the edX page; we link the authors' free book, lectures and self-study homework.

Proof required

Link your public repo or notebook with homework for MapReduce, similar items (min-hashing), link analysis (PageRank) and frequent itemsets, with your code, and a screenshot or log showing the self-check passed.

What gets checked

  • Gradiance scores are shown for each chapter.
  • Your code runs on a dataset too big for one spreadsheet.
  • Results are checked against a small case done by hand.

Common mistakes

  • Copying posted answers: verifiers read the history.
  • Skipping the self-check, then asking for review too early.

A public repo or notebook with homework for MapReduce, similar items (min-hashing), link analysis (PageRank) and frequent itemsets, with your code.

Steps

  1. Make a public repo or notebook first.
  2. Do one unit at a time and commit after each.
  3. Run the self-check: Register for Gradiance self-study with the class token on mmds.org and pass the homework for each chapter.
  4. Write a short README: what is here and how to run it.
  5. Ask three people who know the topic to check it.

What gets sent back

  • No history, just one big upload.
  • Self-check not shown.
  • Code that does not run from the README.

What a verifier looks for

  • Gradiance scores are shown for each chapter.
  • Your code runs on a dataset too big for one spreadsheet.
  • Results are checked against a small case done by hand.
  • Ask one question about a choice in the code; the answer should be clear.

Find similar items at scale

1–3 weeks (5–8 hrs/week)

Use what you learned. Make a program that finds near-duplicates or similar items in a large public dataset (news articles, products, songs) with min-hashing, with timings. Keep it small enough to finish in about two weeks.

Proof required

Link a program that finds near-duplicates or similar items in a large public dataset (news articles, products, songs) with min-hashing, with timings, with a README that says how to run or read it.

What gets checked

  • It runs on the full dataset, not a sample only.
  • A sample of matches is checked by hand.
  • Timings show it scales better than comparing every pair.

Common mistakes

  • A project too big to finish.
  • A demo that only works on your machine.

Powstik Guide

A program that finds near-duplicates or similar items in a large public dataset (news articles, products, songs) with min-hashing, with timings.

Steps

  1. Write one line: what it does and for whom.
  2. Build the smallest version that works.
  3. Test it on someone else's machine or with someone else reading it.
  4. Write the README.
  5. Ask three people to check it.

What gets sent back

  • Does not run from the README.
  • Not clearly the person's own work.
  • Claims more than it does.
