Decision trees | Classification algorithms
In decision tree learning, ID3 (Iterative Dichotomiser 3) is an algorithm invented by Ross Quinlan used to generate a decision tree from a dataset. ID3 is the precursor to the C4.5 algorithm, and is typically used in the machine learning and natural language processing domains. (Wikipedia).

Finding the inverse of a 2x2 matrix
In this video I show you one method of calculating the inverse of a square matrix. We can use this inverse to solve for a system of linear equations. Mathematica has a function called Inverse that easily calculates the inverse of a matrix. You can learn more about Mathematica on my Udem

An identity matrix under matrix multiplication serves a similar role to the number 1, when it comes to integer multiplication, i.e. any number times 1, remains that number. You can learn more about Mathematica on my Udemy course at https://www.udemy.com/mathematica/ PS! Wait until Udemy

Inverse of 3x3 Matrix Using Row Operations 2
Linear Algebra: We compute the inverse of a 3x3 matrix A by applying row operations to the matrix A augmented by the identity matrix. In Part 1, we worked this problem out for a 0-1 matrix; here we use general integers.

How do we add matrices. A matrix is an abstract object that exists in its own right, and in this sense, it is similar to a natural number, or a complex number, or even a polynomial. Each element in a matrix has an address by way of the row in which it is and the column in which it is. Y
