RQ-MoE: Residual Quantization via Mixture of Experts for Efficient Input-Dependent Vector Compression
ICML 2026poster
Vector quantization is a fundamental tool for compressing high-dimensional embeddings, yet existing multi-codebook methods rely on static codebooks that limit expressiveness under heterogeneous data geometry. While recent dynamic quantizers like QINCo adapt codebooks to individual inputs and improve…
