Artificial Intelligence experts cannot live without Linear Algebra:
- AI make heavy use of Scalars
- AI make heavy use of Vectors
- AI make heavy use of Matrices
- AI make heavy use of Tensors
The purpose of this chapter is to highlight the parts of linear algebra that is used in data science projects like machine learning and deep learning.
Vectors and Matrices
Vectors and Matrices are the languages of data.
With AI, most things are done with vectors and matrices.
With vectors and matrices, you can Discover Secrets.
In linear algebra, a scalar is a single number.
const myScalar = 1;
let x = 1;
var y = 1;
In linear algebra, a vector is an array of numbers.
const myArray = [50,60,70,80,90,100,110,120,130,140,150];
myArray.length; // the length of myArray is 11
An array can have multiple dimensions, but a vector is a 1-dimensional array.
A vector can be written in many ways. The most common are:
In linear algebra, a matrix is a 2-dimensional array.
var myArray = [[1,2],[3,4],[5,6]];

A Tensor is an N-dimensional Matrix.
Linear Algebra is the branch of mathematics that concerns linear equations (and linear maps) and their representations in vector spaces and through matrices.
Linear algebra is central to almost all areas of mathematics.
