WebHere we using four minhash functions/vectors to create a four-digit signature vector. If you count (from one) in each minhash function, and identify the first value that aligns with a one in the sparse vector — you will get 2412. At the end of this, we produce our minhash signature — or dense vector. Let’s go ahead and write that in code.
