线性回归:在线性回归中,通过计算特征向量和权重向量之间的点积,建立线性回归模型。 Similarity and Distance Metrics: The dot product of two vectors is a measure of their similarity. When two vectors have a high dot product, it means they are more similar to each other. Similarly, the dot product ...

The dot product operation is communicative: a·b=b·a If the dot product of two not zero vectors is is zero, then these vectors are orthogonal: a≠ 0,b≠ 0,a·b= 0 <=>a┴b (αa) ·b=α(a·b) The dot product operation is distributive: ...
