Struct faiss::ScalarQuantizer::SQDistanceComputer

struct SQDistanceComputer : public faiss::FlatCodesDistanceComputer

Public Functions

inline SQDistanceComputer()

virtual float query_to_code(const uint8_t *code) const = 0

inline virtual float distance_to_code(const uint8_t *code) final: compute distance of current query to an encoded vector

inline virtual float operator()(idx_t i) final: compute distance of vector i to current query

virtual void set_query(const float *x) = 0: called before computing distances. Pointer x should remain valid while operator () is called

virtual float symmetric_dis(idx_t i, idx_t j) = 0: compute distance between two stored vectors
