Aug 7, 2024 · In this article, we will discuss about matrices and matrix arithmetic for machine learning. What is a Matrix? Matrix is a two dimensional array where the data is in the form of rows and columns. The each element in the matrix is represented as a [ i ] [ j ] where i represents the row number and j represents the column number.

Oct 17, 2021 · Matrices are a foundational element of linear algebra. Matrices are used throughout the field of machine learning in the description of algorithms and processes such as the input data variable (X) when training an algorithm. In this tutorial, you will discover matrices in linear algebra and how to manipulate them in Python.

Vector and matrices play a central role in data science: they are probably the most common way of representing data to be analyzed and manipulated by virtually any machine learning or analytics algorithm.
