> Though, conceivably, the codec could quantize the vectors twice (int7, then to bit) and allows you to rerank bit quantized values with int7 quantized values...quantization all the way down I like this idea, it allows more granular trade-off between memory usage and recall. Although if it means we need to store all 3 levels (float32/int7/bit) in disk, or we need to sacrifice accuracy during merging by just relying on the intermediate int7. -- This is an automated message from the Apache Git Service.
