“We study correlation clustering in the streaming setting. This problem has been studied extensively and numerous algorithms have been developed, most requiring multiple passes over the stream. For the important case of single-pass algorithms, recent work of Assadi and Wang [8] obtains a c-approximation using Õ(n) space where c > 105 is a constant and n is the number of vertices to be clustered. We present a single-pass algorithm that obtains a 5-approximation using O(n) space.”
