arXiv:2607.08538v1 Announce Type: cross Abstract: Suppose we observe two sets of $n$ Gaussian vectors in $\mathbb{R}^d$, with the promise that, after applying a permutation of $[n]$ and a rotation of $\mathbb{R}^d$, the two sets are $\rho$-correlated. The Procrustes matching problem asks us to recover the unknown permutation of $[n]$ that aligns the two sets. The problem is well-studied in the low-dimensional regime $d=O(\log n)$, but the high-dimensional regime $d\gg \log n$ has remained largely uncharted: prior matching guarantees require nearly perfect correlation $\rho=1-o(1)$, even for in
This research is published as AI and data science continue to advance, necessitating more sophisticated algorithms for high-dimensional data analysis.
Improved Procrustes matching in high dimensions could enhance data alignment and comparison across various AI applications, such as computer vision and bioinformatics.
The proposed method could enable more accurate data matching under less ideal correlation conditions in high-dimensional spaces, expanding the applicability of Procrustes problems.
