Overview of this book

Machine learning (ML) and high-performance computing (HPC) on AWS run compute-intensive workloads across industries and emerging applications. Its use cases can be linked to various verticals, such as computational fluid dynamics (CFD), genomics, and autonomous vehicles. This book provides end-to-end guidance, starting with HPC concepts for storage and networking. It then progresses to working examples on how to process large datasets using SageMaker Studio and EMR. Next, you’ll learn how to build, train, and deploy large models using distributed training. Later chapters also guide you through deploying models to edge devices using SageMaker and IoT Greengrass, and performance optimization of ML models, for low latency use cases. By the end of this book, you’ll be able to build, train, and deploy your own large-scale ML application, using HPC on AWS, following industry best practices and addressing the key pain points encountered in the application life cycle.

Introduction to optimization

As mentioned in the introduction to this chapter, optimization is an important tool for making decisions related to a large set of problems in our daily lives and various fields of science. There are various components to an optimization problem, as we are going to discuss in the following subsections.

Goal or objective function

The process of optimization starts with defining a goal or an objective, such as monetary gain, a route or path, a schedule, items, and so on. Selecting the goal or objective depends heavily on the problem domain, as well as the specific problem we are trying to solve. In addition to the objective function, we also need to know whether we are maximizing or minimizing the objective function. Again, this also depends on the specific problem domain, as well as the objective function. For an optimization problem with cost as the objective function, our goal will most likely be to minimize it, whereas if our objective function...
