Talk:Cuckoo filter

Layman introduction request
If possible, it would be great to get a layman explanation in the introduction, the guideline Make technical articles understandable might be of help. Would also be useful to mention what the use cases are. – Þjarkur (talk) 00:52, 17 March 2019 (UTC)

fingerprint
The algorithm description section uses a function `fingerprint` without defining it. Can somebody explain what it is/does? 2607:FEA8:1BE0:167C:6C0E:887E:B7EA:4E07 (talk) 19:42, 1 May 2020 (UTC)


 * I agree this is confusing. I'm guessing this is a the same as what the "fingerprint (computing)" article is talking about. How can we make this easier to understand? --DavidCary (talk) 01:06, 28 December 2020 (UTC)
 * It's just a hash function to some desired number of bits. The tradeoff is that if you use more bits it takes that much more space to store them, but you are less likely to get a collision. I agree that the description in the article is not very clear. Fingerprint (computing) is similar but not quite the correct concept, though, because the concept at that article demands that fingerprints be long enough to have essentially no collisions (meaning probably hundreds of bits) while for cuckoo hashing to be useful, the fingerprints should be much shorter than the identifiers for the objects they fingerprint and collisions will still be possible (maybe 8-bit fingerprints would be normal). —David Eppstein (talk) 01:30, 28 December 2020 (UTC)
