This monograph presents the main complexity theorems in convex optimization and their corresponding algorithms. From this perspective, statistical algorithms for solving stochastic convex optimization allow one to convert an In stochastic optimization it discusses stochastic gradient descent, mini-batches, random coordinate descent, and sublinear algorithms. Duality theory. The role of convexity in optimization. We improve upon (Arjevani et al.,2015) by establishing lower bounds which hold both for smooth functions and smooth and strongly convex functions, us- Starting from the fundamental theory of black-box optimization, the material progresses towards recent advances in structural optimization and stochastic optimization. This monograph presents the main complexity theorems in convex optimization and their corresponding algorithms. Starting from the fundamental theory of black-box optimization, the material progresses towards recent advances in structural optimization and stochastic optimization. The presentation of black-box optimization, strongly influenced by the seminal book by Nesterov, includes the analysis of cutting plane methods, as well as (accelerated) gradient descent schemes.
Closed convex functions. It begins with the fundamental theory of black-box optimization and proceeds to guide the reader through recent advances in structural optimization and stochastic optimization. We also briefly touch upon convex relaxation of combinatorial problems and the use of randomness to round solutions, as well as random walks based methods.You will be notified whenever a record that you have chosen has been cited.We use cookies to ensure that we give you the best experience on our website.https://dl.acm.org/doi/10.1561/2200000050Check if you have access through your login credentials or your institution to get full access on this article.To manage your alert preferences, click on the button below.View this article in digital edition.

Convex Optimization: Algorithms and Complexity by Sebastien Bubeck. Our presentation of black-box optimization, strongly influenced by Nesterov's seminal book and … Starting from the fundamental theory of black-box optimization, the material progresses towards recent advances in structural optimization and stochastic optimization. We also pay special attention to non-Euclidean settings relevant algorithms include Frank-Wolfe, mirror descent, and dual averaging and discuss their relevance in machine learning. Our presentation of black-box optimization, strongly influenced by the seminal book of Nesterov, includes the analysis of cutting plane methods, as well as accelerated gradient descent schemes. In stochastic optimization we discuss stochastic gradient descent, mini-batches, random coordinate descent, and sublinear algorithms. It also briefly touches upon convex relaxation of combinatorial problems and the use of randomness to round solutions, as well as random walks based methods. In mathematical optimization, the ellipsoid method is an iterative method for minimizing convex functions.When specialized to solving feasible linear optimization problems with rational data, the ellipsoid method is an algorithm which finds an optimal solution in a finite number of steps..
