My binary vector search is better than your FP32 vectors

Within the field of vector search, an intriguing development has arisen: binary vector search. This approach shows promise in tackling the long-standing issue of memory consumption by achieving a remarkable 30x reduction. However, a critical aspect that sparks debate is its effect on accuracy.

We believe that using binary vector search, along with specific optimization techniques, can maintain similar accuracy. To provide clarity on this subject, we showcase a series of experiments that will demonstrate the effects and implications of …
