  • Quantization method for feature vector, search method, apparatus and storage medium
    Patent number: 11308152
    Abstract: Embodiments of the present disclosure provide a quantization method of feature vector, search method, apparatus and storage medium, wherein the quantization method comprises: setting quantization codewords; selecting, from the set quantization codewords, at least one quantization codeword of which distance from an original feature vector is smaller than first predetermined distance as a quantization codeword subset; determining quantization feature vectors corresponding to the original feature vector by using at least two quantization codewords, wherein at least one quantization codeword from the at least two quantization codewords are in the quantization codeword subset. The search method is a method of performing a search among quantization feature vectors after a quantization using the quantization method.
