Vectors

Definition 1. A vector in a vector space $V$ over a field $F$ is a set of elements of $V$ that is closed under addition and scalar multiplication. In other words, if $u$ and $v$ are vectors in $V$ and $a$ is a scalar in $F$, then $u+v$ and $au$ are also vectors in $V$….

I have been reviewing Linear Algebra concepts to get a better grasp of Machine Learning through a MOOC called “Mathematics for Machine Learning: Linear Algebra” offered by the Imperial College of London on Coursera. This blog post aims to summarize some of the basic concepts in Linear Algebra. Vectors What are vectors? Geometric representation of a vector…
