We recognize this expression as just the scalar product.

可以认出，此表达式正好就是标积。

Scalar Product Protocol is the keystone in building privacy-preserving decision tree.

标量积协议是构造隐私保持决策树的关键技术。

The scalar product of a vector with itself is the square of the magnitude of the vector.

一个矢量自身相乘的标积等于该矢量大小的平方。

There are two ways that we multiply vectors and one is called the "dot product" often also called the scalar product.

矢量乘法有两种,一种叫做“点积“,通常也被叫作“数量积

We prefer the form (5.16.7) since it is in conformity with the definition of scalar product in a complex Euclidean space.

我们愿意用(5.16.7)这种形式，因为它和复欧几里德空间中标积之定义相谐调。
