This page collects together the posts for the graduate course on optimization I taught at Princeton in the Spring 2013. This material has been reorganized (some parts have been cut, some have been extended) into a monograph which got recently published “Foundations and Trends in Machine Learning, Vol. 8: No. 3-4, pp 231-357, 2015” (see here for the free version):
Part I: Computational complexity of optimization
Post 1: Introduction
Post 2: The ellipsoid method
Post 3: LP, SDP, and Conic Programming
Post 4: Interior Point Methods
Post 5: IPMs for LPs and SDPs
Post 6: Lagrangian duality
Post 7: Classification, SVM, Kernel Learning
Post 8: Turing Machines
Post 9: P vs. NP, NP-completeness
Post 10: Getting around NP-hardness
Bonus lectures by Amir Ali Ahmadi: Sum of Squares (SOS) Techniques: An Introduction, Part I, and Part II
Part II: Oracle complexity of optimization
Post 11: Oracle complexity, large-scale optimization
Post 12: Oracle complexity of Lipschitz convex functions
Post 13: Oracle complexity of smooth convex functions
Post 14: Nesterov’s Accelerated Gradient Descent
Post 15: Strong convexity (added in 2014: Nesterov’s Accelerated Gradient Descent for Smooth and Strongly Convex Optimization)
Post 16: Conditional Gradient Descent and Structured Sparsity
Post 17: ISTA and FISTA
Post 18: Mirror Descent, part I/II
Post 19: Mirror Descent, part II/II
Post 20: Mirror Prox
Part III: Optimization and Randomness
Post 21: Noisy oracles (for stochastic approximation and acceleration by randomization)
Post 22: Acceleration by randomization for a sum of smooth and strongly convex functions
Post 23: Optimization with bandit feedback
Final exam
