Чтение книги онлайн.

СКАЧАТЬ becoming status symbols in the computer service industry. Organizations, including members of the computer service industry, are recognizing the benefits of cloud certification such as the AWS Solution Architect Professional, Certified Security, and Advanced Networking Specialty. As ML becomes increasingly popular, these certifications provide proof of your understanding of ML and your ability to practically deploy ML solutions on AWS.

       It provides an opportunity for advancement. The solution architect role is one of the most coveted roles in the tech industry today due to the breadth and depth of the knowledge you gain, while having an outsized impact on customers’ business. The Machine Learning Specialty Certification could provide you with an opportunity to specialize in ML and become a practicing ML architect, a unique role that many employers are looking to hire.

       It helps you develop an industry understanding of ML. ML education is rapidly becoming a crowded space with blogs, textbooks, online courses that cover the foundations of ML, statistics and data science, and even ML tooling. However, there is no substitute for experience, and there isn't much material on actual industry use cases with solutions and best practices (with the exception of some fantastic tech blogs published by companies like Uber, Google, Netflix, Lyft, Airbnb, and many others). This book aims to cover some of that gap by providing you with a practical understanding of building real-life ML solutions on AWS.

       It will satisfy your curiosity. As technologists and technology enthusiasts, we are constantly learning new areas and expanding our knowledge. One of the best and most fulfilling reasons to take this certification is simply to satiate your curiosity to learn how to build ML solutions on AWS.

      How to Become AWS Machine Learning Specialty Certified

      The AWS Certified Machine Learning Specialty exam is available to anyone and does not require other AWS certifications as prerequisites. It is recommended, however, that you have 1–2 years of experience developing and architecting ML and deep learning workloads on AWS prior to taking the test. Because it is a specialty certification, it also assumes prior foundational understanding of AWS services for storage, networking, security, databases, and so forth; however, these are not tested in detail.

      The exam is administered by Pearson VUE and PSI. To register for the test with PSI, you can register online at https://awsavailability.psiexams.com. To register with Pearson VUE, you can register online using https://home.pearsonvue.com/Clients/Amazon-Web-Services.aspx.

      Exam policies can change from time to time. We highly recommend that you check both the PSI and Pearson VUE sites for the most up-to-date information when you begin preparing, when you register, and again a few days before your scheduled exam date.

Who Should Buy This Book

      Anybody who wants to pass the AWS Certified Machine Learning Specialty exam may benefit from this book. This book is also helpful for business and IT professionals who want to learn how ML is practically used in the industry and pivot their careers toward an ML-centric role such as a data scientist or ML engineer working on AWS. We include a number of practical case studies, industry best practices, and architecture patterns that we have seen used in industry today from our engagements with hundreds of AWS customers. This book is also essential for data scientists, engineers, and other data professionals who are curious about how you can build, train, and deploy models at scale on AWS.

This book assumes some familiarity with ML and with AWS. If you are completely new to machine learning, we recommend that you first learn some basic ML concepts since this book is mainly focused on the practical aspects of building ML solutions. There are several great resources that cover ML foundations, particularly for building statistical models and for deep learning. Two of our favorites are Aurélion Géron's Hands-on Machine Learning with Scikit-learn and TensorFlow (O'Reilly Publishing) and Francois Chollet's Deep Learning with Python (Manning, 2017). There are also several awesome blogs on Medium.com and TowardsDataScience.com. Finally, we also recommend a number of industry blogs from leading tech companies like Uber, Google, Facebook, Amazon, Airbnb, and others on how they deploy large-scale ML solutions to have a holistic understanding of the industry landscape in this space.

      As a practical matter, you'll need a laptop or desktop with which to practice and learn in a hands-on way. This book does not cover labs, and there is no substitute for hands-on experience. Go get familiar with AWS ML services such as SageMaker, as well as the AI services, before taking the test. We also recommend that you explore some public datasets, engineer features, and train simple models as well as some deep learning models.

Study Guide Features

      This study guide uses a number of common elements to help you prepare. These include the following:

       Summaries The summary section of each chapter briefly explains the chapter, allowing you to easily understand what it covers.

       Exam Essentials The Exam Essentials focus on major exam topics and critical knowledge that you should take into the test. They focus on the exam objectives provided by AWS.
