The Brief
What you'll do, and what you'll demonstrate.
Build a MinHash + LSH sketch that finds near-duplicate job postings at a Jaccard threshold of 0.7 with at least 95 percent recall and at least 85 percent precision.
Earning criteria — what you'll demonstrate
- Derive the relationship between LSH bands (b), rows per band (r), and the S-curve probability of collision
- Implement MinHash with permutation-based hashing without leaking bias
- Measure approximate-vs-exact deduplication quality with labeled data
- Reason about the recall/precision trade controlled by b and r
