Module aimsTo develop a deeper understanding of optimal decision making models, algorithms and applications to engineering, finance, and machine learning. To provide an insight for algorithm design and formulation of decision models.
Learning outcomesThe student will be able to analyse algorithms and judge the performance of algorithms and interpret their results. The course opens into issues related to current research. Knowledge and Understanding Explain when a solution to a nonlinear optimisation problem is optimal; Describe zeroth-, first-, and second-order algorithms for converging to a optimal point; Recall the difference between local and global convergence; Understand the property of convexity and how it impacts optimisation; State the differences between constrained and unconstrained optimisation; Describe what is the best algorithm for a given problem and explain why. Intellectual Skills Prove convexity of a function and of an optimisation problem; Specify the optimality conditions for both constrained and unconstrained optimisation problems; Derive basic zeroth-, first-, and second-order optimisation algorithms and evaluate their convergence; Practical skills Apply optimisation algorithms to machine learning applications, e.g. recognising hand-writing and robust principal component analysis; Program basic zeroth-, first-, and second-order optimisation algorithms; Apply knowledge towards being able to read research papers in the area;
