Matrix Calculus for Data Science and Machine Learning

Machine learning algorithms often seem like black boxes, but their core learning mechanism relies on a single mathematical concept: matrix calculus. This written course demystifies the mathematics behind modern optimization, helping you understand how gradients drive neural networks, regression models, and classification algorithms. What you will learn: • Understand foundational concepts of vector and matrix derivatives • Calculate gradients, Jacobians, and Hessian matrices for multi-variable functions • Apply the matrix chain rule to derive backpropagation steps in neural networks • Analyze optimization algorithms like gradient descent from a mathematical perspective • Explore modern automatic differentiation concepts used in machine learning frameworks. You will begin with key terminology and foundational definitions before moving step-by-step into vector derivatives, matrix operations, and their direct applications in training algorithms. This course is designed for aspiring data scientists and machine learning beginners who want to build a solid mathematical foundation with no advanced prerequisites. Read and master the mathematical engine that powers modern artificial intelligence.
