New framework analyzes MAXCUT-based clustering algorithms with theoretical guarantees

This paper introduces a new framework for analyzing three algorithms—SDP1, BalancedSDP, and Spectral clustering—used for partitioning data samples drawn from mixtures of two sub-Gaussian distributions. The researchers provide unified theoretical guarantees for these algorithms, showing they can achieve polynomial-rate misclassification even with partial recovery, as long as a defined signal-to-noise ratio (SNR) is sufficiently high. Furthermore, the study demonstrates that the misclassification errors for SDP1 and BalancedSDP decay exponentially with the SNR, with BalancedSDP requiring no explicit debiasing when cluster sizes are equal.

    Semidefinite programming relaxations and debiasing for MAXCUT-based clustering

    arXiv:2401.10927v3 Announce Type: replace Abstract: In this paper, we consider the problem of partitioning a small data sample of size $n$ drawn from a mixture of $2$ sub-gaussian distributions in $\mathbb{R}^p$. We consider semidefinite programming relaxations of an integer quad…
