The Magic of Vector-Matrix Multiplication: A Deep Dive Inside - postfix
How is vector-matrix multiplication used in machine learning?
At its core, vector-matrix multiplication is a straightforward operation that combines two fundamental concepts in mathematics: vectors and matrices. A vector is a mathematical object with both magnitude and direction, while a matrix is a rectangular array of numbers. When you multiply a matrix by a vector, you're essentially performing a series of dot products, which results in a new vector. This operation can be thought of as a linear transformation that maps one vector to another.
