How does minhash work
WebHow does Minhash LSH work? A minhash function converts tokenized text into a set of hash integers, then selects the minimum value. This is the equivalent of randomly selecting a token. The function then does the same thing repeatedly with different hashing functions, in effect selecting n random shingles. ...

WebJun 29, 2024 · Now you may be thinking that we can stop here. But if you think about the scalability, doing just this won’t work. For a collection of n documents, you need to do n*(n-1)/2 comparison, basically O(n²). Imagine you have 1 million documents, then the number of comparison will be 5*10¹¹ (not scalable at all!). Space complexity Websourmash is a command-line tool and Python library for computing hash sketches from DNA sequences, comparing them to each other, and plotting the results. This allows you to estimate sequence similarity between even very large data sets quickly and accurately.
