Next, it offers some basic Transformers examples using the Google colab engine. Then, it introduces the Hugging Face ecosystem and the different libraries and models provided by it. Moving forward, it explains language models such as Google BERT with some examples before providing a deep dive into Hugging Face API using different language models to address tasks such as sentence classification, sentiment analysis, summarization, and text generation. After completing Introduction to Transformers for NLP, you will understand Transformer concepts and be able to solve problems using the Hugging Face library. What You Will Learn Understand language models and their importance in NLP and NLU (Natural Language Understanding) Master Transformer architecture through practical examples Use the Hugging Face library in Transformer-based language models Create a simple code generator in Python based on Transformer architecture Who This Book Is ForData Scientists and software developers interested in developing their skills in NLP and NLU (Natural Language Understanding)

Journey into the amazing world of WebAssembly (Wasm) and learn about how it can be applied on the cloud. This book is an introduction to Wasm aimed at professionals accustomed to working with cloud-related technologies such as Kubernetes and Istio service mesh. Author Shashank Jain begins with an introduction to Wasm and its related tooling such as wasm-bindgen and wapc. He then walks you through code examples using Rust, Golang, and JavaScript to demonstrate how they can be compiled to Wasm and consumed from Wasm runtimes deployed standalone, as well as on the cloud. You will see how a wasm module can be run through an http interface, and how Wasm fits into CNCF projects such as Kubernetes and Istio service mesh. After that, you'll learn how the polyglot nature of WebAssembly can be leveraged through examples written in languages like Rust and consumed via Golang and JavaScript, with a focus on how WebAssembly allows interoperability between them. You'll gain an understanding of how Wasm-based modules can be deployed inside Linux containers and orchestrated via Kubernetes, and how Wasm can be used within the Istio proxy to apply rules and filters. After reading this book, you'll have the knowledge necessary to apply WebAssembly to create multi tenanted workloads which can be polyglot in nature and can be deployed on cloud environments like Kubernetes. What You Will Learn Understand how Wasm can be used for server-side applications Learn about Wasm memory model and Wasm module layout How communication between host and Wasm module is facilitated The basics of Wasm sandboxing and security The fundamentals of tooling around Wasm, such as WAT and Wasm-pack Create a Wasm module in Rust and consume it from JavaScript, Rust and Golang. Grasp how Kubernetes can be used to orchestrate Wasm-based workloads How Wasm fits into service mesh Who Is This Book For Software developers/architects who are looking to hone their skills in virtualization and explore alternatives to Docker and container-based technologies for their workload deployments. Readers should have a basic programming background in languages such as Rust and Golang to get the most out of this book.

New drilling techniques for oil and natural gas are propelling an energy production renaissance in the United States. As the US economy struggles to emerge from the Great Recession, many see the boom as a possible source of economic salvation that could reduce unemployment and revitalize American manufacturing. Until now, however, there has been little objective analysis of the energy boom's economic consequences. In this major study, Trevor Houser and Shashank Mohan fill that gap. They assess the impact of the recent and projected increase in domestic energy production on US GDP, employment growth, manufacturing competitiveness, household expenditures, and international trade balance. Alongside its economic impact, the American energy revolution is raising new environmental and trade policy questions. What are the consequences for the environment and global warming of increased domestic oil and gas production? Should companies be allowed to export the energy they produce or will doing so undermine American manufacturing competitiveness? Houser and Mohan provide independent research and analysis that will help policymakers navigate these issues.

This book is a one-stop guide for IT professionals with a background in traditional and software-defined networks looking to expand or hone their skill set and has been developed through a combination of extensive research and testing in both development and production environments. It provides reliable information on a fundamental component of NSX-T, logical routing. A comprehensive understanding of this capability will help IT professionals with design, implementation, troubleshooting, and enhancements. The book starts with an introduction to the foundational components of the NSX-T platform and how NSX-T fits into the software-defined data center. The focus then moves to tunnel endpoints, which is a critical aspect of the NSX-T platform, and the differences between overlays and underlays are explained. Once the basics are covered, it provides a detailed description of how NSX-T components communicate. Next, the book introduces logical routing and its components and provides a better understanding of how these components function with one another. Several packet walks are illustrated to explain NSX-T logical routing behavior in different scenarios. After mastering logical routing, it explains how NSX-T ensures data plane availability, which is explored at various layers of NSX-T. Finally, the book explores the concepts and intricacies of routing into and out of the NSX-T environment. It deep dives into utilizing the Border Gateway Protocol (BGP), Open Shortest Path First (OSPF), and Static Routing. What You Will Learn Know how VMware NSX-T endpoints communicate Understand how NSX-T logical routing works Know how NSX-T provides high availability for the data plane Understand how NSX-T operates with static and dynamic routing protocols Configure the platform Who This Book Is For Readers with an intermediate to advanced skill set who wish to further their knowledge, those who focus on datacenter technology, those planning to move to a software-defined datacenter to transform the way their current datacenter works, and anyone looking to learn about VMware NSX-T and how it operates
