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.

Machine learning and numerical optimization

So far, we have discussed numerical optimization and its use cases from an optimization problems perspective. Whereas numerical optimization has several standalone industry use cases and applications, it is also very commonly used in several machine learning algorithms and use cases. Whether it’s supervised learning, unsupervised learning, or reinforcement, we are always solving some form of optimization problem using iterative processes at the very core of a machine learning algorithm.

In supervised learning, for example, let’s look at the case of linear regression. In linear regression, we are minimizing a cost function consisting generally of the mean squared error between the actual value of a target variable and the value predicted via the model.

Our algorithm arrives at the minimum value of the cost function (convex function with a global minimum if it is mean squared error, non-convex with local minima in most other...
