Introduction Linear Algebra forms the mathematical backbone of data science, machine learning, artificial intelligence, and many modern computational systems.Whenever we work with datasets, train models, or visualize information, we are implicitly working with mathematical structures such as scalars, vectors, and matrices. In this tutorial, we will focus on two foundational concepts: scalars and vectors, which…

When you start learning machine learning or data science, you quickly realize that the core difficulty is not writing code, but representing and manipulating data that has many dimensions. A single data point is rarely just one number. It is usually a collection of related values: features, measurements, signals, or attributes. Linear algebra is the…
