SAQ: Pushing the Limits of Vector Quantization through Code Adjustment and Dimension Segmentation

Summary: SAQ segments PCA-projected vectors and DP-optimizes bit allocation to favor high-magnitude segments, lowering quantization error. A coordinate-descent code-adjustment encodes dimensions independently then refines, avoiding enumeration and yielding up to 80% error reduction and >80× encoding speedup over Extended RabitQ.
