New research proposes variable bit allocation for embedding quantization

A new research paper proposes a variable bit allocation framework for embedding quantization, moving beyond uniform bit distribution. This method partitions embeddings into buckets and non-uniformly allocates storage, showing significant improvements in recall for embeddings with the Matryoshka property. The variable allocation strategy outperforms uniform baselines, especially in low-bit regimes, by up to 8% for Product Quantization and 18% for Scalar Quantization. AI

IMPACT This research could lead to more efficient storage and retrieval of large-scale embeddings, impacting the performance of AI systems that rely on these representations.
