The Bloom Filter I Programmer

What this implementation does is focus your attention on some of the difficulties of implementing a good Bloom filter. The first simplicity is that instead of custom crafting a bit array we can use the supplied BitArray object.

Bloom Filters by Example Bill Mill

Bloom Filters by Example. A Bloom filter is a data structure designed to tell you, rapidly and memory-efficiently, whether an element is present in a set. The price paid for this efficiency is that a Bloom filter is a probabilistic data structure: it tells us that the element either definitely is not in the set or may be in the set.

unit testing Bloom-filter implementation in Clojure

Background. Bloom-filter is a data structure to which we can insert elements, and check if it already contains a given element. The peculiarity is, that if a contains query returns true, then it might still be possible, that in fact, this element was not inserted to the filter.(If, on the other hand, it returns false, then the element was definitely not inserted previously.)

Bloom Filter Brilliant Math & Science Wiki

A bloom filter is a probabilistic data structure that is based on hashing. It is extremely space efficient and is typically used to add elements to a set and test if an element is in a set. Though, the elements themselves are not added to a set. Instead a hash of the elements is added to the set. When testing if an element is in the bloom filter, false positives are possible. It will

Implementing a custom Redis and in-memory bloom filter

In-memory Bloom filter. With the Redis implementation we solved half of the problem. We have a way to concurrently and quickly add elements to the bloom filter in Redis, but we still need a way to check if a bloom filter could accept a given set of elements without actually inserting the elements in the filter.
