In this tutorial, we will learn how to calculate cosine similarity between two matrices using MATLAB. So, let’s start with the basic definition of cosine similarity. What is Cosine Similarity? Cosine similarity is a standard of measurement in matrix algebra used to determine the measure of similarity between two non-zero matrices in an inner product space like Euclidean space. Cosine similarity measures the cosine of the angle between the two matrices and produces a value between -1 and 1. Here, the value 1 indicates that the two matrices are perfectly similar, and the value -1 indicates that the two matrices ... Read More
