AWS Certified Machine Learning Specialty: MLS-C01 Certification Guide

By: Somanath Nanda, Weslley Moura

Overview of this book

The AWS Certified Machine Learning Specialty exam tests your competency to perform machine learning (ML) on AWS infrastructure. This book covers the entire exam syllabus using practical examples to help you with your real-world machine learning projects on AWS. Starting with an introduction to machine learning on AWS, you'll learn the fundamentals of machine learning and explore important AWS services for artificial intelligence (AI). You'll then see how to prepare data for machine learning and discover a wide variety of techniques for data manipulation and transformation for different types of variables. The book also shows you how to handle missing data and outliers and takes you through various machine learning tasks such as classification, regression, clustering, forecasting, anomaly detection, text mining, and image processing, along with the specific ML algorithms you need to know to pass the exam. Finally, you'll explore model evaluation, optimization, and deployment and get to grips with deploying models in a production environment and monitoring them. By the end of this book, you'll have gained knowledge of the key challenges in machine learning and the solutions that AWS has released for each of them, along with the tools, methods, and techniques commonly used in each domain of AWS ML.

Working with Step Functions

Step Functions is an AWS service that allows you to create workflows in order to orchestrate the execution of Lambda Functions. This is so that you can connect them in a sort of event sequence, known as steps. These steps are grouped in a state machine.

Step Functions incorporates retry functionality so that you can configure your pipeline to proceed only after a particular step has succeeded. The way you set these retry configurations is by creating a retry policy.

Important note

Just like the majority of AWS services, AWS Step Functions also integrates with other services, not only AWS Lambda.

Creating a state machine is relatively simple. All you have to do is navigate to the AWS Step Functions console, then create a new state machine. On the Create state machine page, you can specify whether you want to create your state machine from scratch, from a template, or whether you just want to run a sample project.
