Unified Comparison of Rotation-Based Vector Quantizers
A recent paper on arXiv presents a comprehensive theoretical analysis of rotation-based vector quantizers, namely EDEN, RabitQ, and TurboQuant, highlighting that their respective benefits vary based on the distortion criteria used. Both EDEN and TurboQuant perform exceptionally well with MSE distortion. In contrast, EDEN is noted for its efficiency with expected inner-product distortion, while RabitQ is recognized for its robust high-probability control. The study emphasizes that EDEN delivers notably strong assurances regarding expected distortion measures.
