The Ultimate Guide to Online Convex Optimization

Online Convex Optimization (OCO) has become an essential tool for tackling optimization problems in various domains, ranging from machine learning to online advertising. In this article, we will delve into the world of OCO and introduce you to the second edition of the renowned book " to Online Convex Optimization: Second Edition" by Elad Hazan.

What is Online Convex Optimization?

Online Convex Optimization is a framework that enables the optimization of an objective function over a sequence of decision rounds. In each round, the decision maker observes some information about the environment and needs to make a decision that minimizes the cumulative loss over time. The objective function is usually assumed to be convex, which allows for efficient algorithms to be developed.

OCO is particularly useful in scenarios where data arrives sequentially and decisions need to be made in real-time, such as in online advertising, financial trading, and routing problems. By adapting to changing environments, OCO algorithms can make optimal decisions even with limited knowledge of future information.

New edition of a graduate-level textbook on that focuses on online convex optimization, a machine learning framework that views optimization as a process.

In many practical applications, the environment is so complex that it is not feasible to lay out a comprehensive theoretical model and use classical algorithmic theory and/or mathematical optimization. to Online Convex Optimization presents a robust machine learning approach that contains elements of mathematical optimization, game theory, and learning theory: an optimization method that learns from experience as more aspects of the problem are observed. This view of optimization as a process has led to some spectacular successes in modeling and systems that have become part of our daily lives.

Based on the “Theoretical Machine Learning” course taught by the author at Princeton University, the second edition of this widely used graduate level text features:
  •  Thoroughly updated material throughout
  •  New chapters on boosting, adaptive regret, and approachability and expanded exposition on optimization
  •  Examples of applications, including prediction from expert advice, portfolio selection, matrix completion and recommendation systems, SVM training, offered throughout
  •  Exercises that guide students in completing parts of proofs
