强化学习:使用一个策略函数(policy function)来决定智能体在当前状态下应该采取什么样的行动。策略函数通常由一个权重向量(weight vector)和一个状态向量(state vector)的点积计算得到。 推荐系统:在推荐系统中,常常需要计算用户和物品之间的相似度,可以使用点积运算。
The dot product of a vector with itself is always greater than zero or equal to zero: a·a≥ 0 The dot product of a vector with itself is zero if and only if the vector is the zero vector: a·a= 0 <=>a=0 The dot product of a vector with itself is equal to the square of ...
