TARGETED CLUSTERING SYSTEM AND METHOD

There is disclosed a computer-implemented system and method of classifying a target sample, wherein the target sample is a computer object having a feature vector, the method comprising: creating n sorted containers, comprising sorting a universe of samples based on feature vector distances from the samples to n vantage points, wherein n is a positive integer; storing the n sorted containers to a computer memory; bucketizing the n sorted containers; for the n vantage points, selecting, from the n bucketized sorted containers, n meta-buckets of that the target sample belongs to; creating an intersection container, comprising samples that appear in all n meta-buckets; selecting, as a target cluster, samples from the intersection container that have a feature vector distance from the target sample less than a threshold; and acting on the target cluster.
