Foundations of Convex Optimization: Theory and Application

Optimization is at the heart of modern decision-making, machine learning algorithms, and engineering design. Understanding the mathematical principles of convex optimization allows you to formulate and solve complex problems efficiently and reliably. This text-only course guides you from the absolute basics of convex sets and functions to formulating and solving optimization problems. You will develop a strong conceptual framework, learning how to recognize convex problems and apply standard optimization techniques to real-world scenarios. What you'll learn: - Understand the fundamental definitions of convex sets, hyperplanes, and convex functions. - Formulate optimization problems mathematically and determine whether they are convex. - Learn key optimization algorithms, including gradient descent and interior-point methods. - Apply duality theory to find bounds and interpret Lagrange multipliers. - Solve practical problems in machine learning, signal processing, and resource allocation. - Analyze optimization trade-offs and convergence rates for different algorithms. You will start with core mathematical definitions and basic properties of convex sets before moving on to duality, optimality conditions, and modern algorithmic applications. Each module includes written explanations, step-by-step mathematical proofs, and practical formulation exercises. This course is designed for beginners in data science, engineering, or quantitative finance. A basic understanding of linear algebra and calculus is helpful, but no prior optimization experience is required.
