Can we construct … WebApr 20, 2024 · If you already know the vectors are both normalized (of length one), then the dot product equaling one means that the vectors are pointing in the same direction (which also means they’re equal). For example, 2D vectors of (2, 0) and (0.5, 0) have a dot product of 2 * 0.5 + 0 * 0 which is 1 .

WebThe dot product as projection. The dot product of the vectors a (in blue) and b (in green), when divided by the magnitude of b, is the projection of a onto b. This projection is illustrated by the red line segment from the tail … WebAnswer (1 of 2): Yep. The most general way to describe a word vector (a.k.a. embedding) is the following. It is an N-dimensional vector (a vector in \mathbb{R}^N) that describes a word. Two vectors in \mathbb{R}^N can definitely have a negative dot product. For example,[+1, +1, \dots, +1] and [-...
WebDot product or scalar product of two vectors a and b, denoted by a·b, is the scalar ab cos θ where a and b are the magnitudes of the vectors a and b and θ is the angle between the vectors a and b measured in the … WebAnswer (1 of 3): If the angle between two vectors is acute, then their scalar product (also called dot product and inner product) is positive. If the angle between two vectors is right, then their scalar product is zero. If the angle between two vectors is obtuse, then their scalar product is n...
