Beyond Product Quantization: Deep Progressive Quantization for Image Retrieval

16 Jun 2019Lianli GaoXiaosu ZhuJingkuan SongZhou ZhaoHeng Tao Shen

Product Quantization (PQ) has long been a mainstream for generating an exponentially large codebook at very low memory/time cost. Despite its success, PQ is still tricky for the decomposition of high-dimensional vector space, and the retraining of model is usually unavoidable when the code length changes... (read more)
