Key things to remember
- The API for the randomized methods we studied: Bloom filters, LSH, CM sketches, and specifically, when you would use which technique.
- The relationship between hash kernels and CM sketches.
- What are the key tradeoffs associated with these methods, in terms of space/time efficiency and accuracy, and what sorts of errors are made by which algorithms (e.g., if they give over/under estimates, false positives/false negatives, etc).
- What guarantees are possible, and how space grows as you require more accuracy.
- Which algorithms allow one to combine sketches easily.
