Applications of Optimization in Machine Learning

Mathematical Optimization

Introduction

From scheduling flights and routing delivery trucks to training neural networks, optimization algorithms drive decision-making across industry and science. This guide examines a key method in this practically important branch of mathematics. Mathematical optimization is the study of choosing the best option from a set of alternatives, providing the theory and algorithms that drive decision-making in industry, science, and machine learning.

Empirical risk minimization

Optimization researchers use machine learning optimization to design algorithms that scale to problems with millions of variables, from logistics networks to deep learning models.

A concrete example of machine learning optimization in action can be seen in machine learning, where gradient descent and its variants train neural networks by minimizing loss functions.

Optimizing neural networks

The concept of training neural networks plays a key role in formulating real-world decision problems as mathematical programs that can be solved efficiently and reliably.

For instance, applying training neural networks allows companies to schedule deliveries, allocate budgets, and design networks that minimize cost while meeting demand.

Regularization as optimization

The concept of regularization plays a key role in formulating real-world decision problems as mathematical programs that can be solved efficiently and reliably.

A concrete example of regularization in action can be seen in machine learning, where gradient descent and its variants train neural networks by minimizing loss functions.

Key Fact: The simplex method has exponential worst-case behavior — early adversarial examples designed by Victor Klee and George Minty force it to take exponentially many pivots — yet its average performance in practice is excellent.

Large-scale training

The properties of empirical risk minimization reveal how convexity, duality, and optimality conditions provide theoretical guarantees for the quality of computed solutions.

A concrete example of empirical risk minimization in action can be seen in machine learning, where gradient descent and its variants train neural networks by minimizing loss functions.
