这里比上文提到的多了三个算法,一是VerifyUPK用来验证更新密钥的正确性,二是EmptyCommit用来验证承诺是否为空,三是AggregateProofs用来将多个证明聚合。 3.2 From KZG to aSVC 我们现在考虑一下如何利用KZG构建一个aSVC。KZG是一个多项式承诺,所以首先我们需要根据要承诺的向量构建多项式。首先假设对于向量\textbf{v}=...

顺序容器首选 vector，关联容器首选 unordered_map。当这两个不满足需求时再考虑别的容器。

By default, the system queries the neighbor vectors of the specified vector in each index, aggregates the obtained vectors, and returns the neighbor vectors that are the nearest to the specified vector. Valid values: 1 to 10000. vector: the vector whose nearest neighbors you want to query. ...

<parameter-name> field specifies one of the entries for the PARAM table of the FT.SEARCH or FT.AGGREGATE command. This parameter is the reference vector value for distance computations. The value of the vector is encoded into the PARAM value in little-endian IEEE 754 binary format (same enco...
