Product quantization is an effective quantization scheme, with that a high-dimensional space is decomposed into a Cartesian product of low-dimensional subspaces, and quantization in different subspaces is conducted separately. We briefly discuss the factors for designing a product quantizer, and then design experiments to comprehensively investigate how these factors influence performance of image search. By this evaluation we reveal design principles that have not been well investigated before.
