New approach extends CMinHash algorithm for improved variance analysis

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a novel approach to analyze and extend the CMinHash algorithm, a method for MinHash estimation. This new technique provides explicit and comparable approximate variance expressions, which were previously difficult to derive for other MinHash estimators. The proposed method was used to analyze the Minner estimator, and numerical experiments confirmed that the derived variance expressions accurately predict the empirical mean square error of estimates. This work paves the way for applying circulant permutation to a broader range of MinHash estimators and calculating their approximate variances. AI

IMPACT This research offers a more robust method for analyzing and potentially improving data sketching techniques used in large-scale data processing and similarity search.

    Understanding Circulant Permutation to Extend the CMinHash Estimator

    arXiv:2610.18551v1 Announce Type: new Abstract: CMinHash promises a new direction for designing MinHash algorithms with reduced variance and storage space via circulant permutations. However, the original variance analysis is difficult to extend to other MinHash estimators. We pr…
