Linear algebra
As we’ve already seen, a movie recommendation engine utilizes several mathematical concepts to provide accurate and personalized recommendations to users. However, in a scenario where a vast collection of 10,000 movies is available for recommendation, computational efficiency becomes a crucial factor. Linear algebra, an area of mathematics that deals with matrices and vectors, provides the necessary tools to perform these calculations efficiently.
Linear algebra focuses on analyzing and manipulating matrices and vectors to extract useful information and apply it in practical situations. As we proceed, it is important to have a solid understanding of the basic principles of linear algebra. Therefore, we will be reviewing several key rules of linear algebra before delving further into the topic.
Matrix multiplication
Like numbers, we can multiply matrices together. Multiplying matrices is, in essence, a mass-produced way of taking several dot products at...
