WebUnit Vectors. A vector of a norm of 1 is a unit vector. Unit vectors are of use when length is not relevant. The unit vector $\textbf{u}$ is defined as: \[\displaystyle \textbf{u} = \dfrac{1}{ \textbf{v} } \cdot \textbf{v}\] where v is a non-zero vector in $\mathbb{R}^{n}$. When we obtain a unit vector u from v, it is called normalizing v. Web26 de mar. de 2024 · We will take a look at a few common vector norm calculations used in machine learning. 1.
