Vector Definition DeepAI

In mathematics, the pointwise product of two functions is another function, obtained by multiplying the images of the two functions at each value in the domain. If f and g are both functions with domain X and codomain Y, and elements of Y can be multiplied (for instance, Y could be some set of numbers), then the pointwise product of f and g is another function from X to Y which maps x in X to f (x)g(x) in Y.

WebThe inner product of two tensors is a generalization of the dot product operation for vectors as calculated by dot. A dot product operation (multiply and sum) is performed on all corresponding dimensions in the tensors, so the operation returns a scalar value. For this operation, the tensors must have the same size.
