Advanced Forecasting with Python
Cover all the machine learning techniques relevant for forecasting problems, ranging from univariate and multivariate time series to supervised learning, to state-of-the-art deep forecasting models such as LSTMs, recurrent neural networks, Facebook’s open-source Prophet model, and Amazon’s DeepAR model.Rather than focus on a specific set of models, this book presents an exhaustive overview of all the techniques relevant to practitioners of forecasting. It begins by explaining the different categories of models that are relevant for forecasting in a high-level language. Next, it covers univariate and multivariate time series models followed by advanced machine learning and deep learning models. It concludes with reflections on model selection such as benchmark scores vs. understandability of models vs. compute time, and automated retraining and updating of models.Each of the models presented in this book is covered in depth, with an intuitive simple explanation of the model, a mathematical transcription of the idea, and Python code that applies the model to an example data set.Reading this book will add a competitive edge to your current forecasting skillset. The book is also adapted to those who have recently started working on forecasting tasks and are looking for an exhaustive book that allows them to start with traditional models and gradually move into more and more advanced models.WHAT YOU WILL LEARN* Carry out forecasting with Python* Mathematically and intuitively understand traditional forecasting models and state-of-the-art machine learning techniques* Gain the basics of forecasting and machine learning, including evaluation of models, cross-validation, and back testing* Select the right model for the right use caseWho This Book Is ForThe advanced nature of the later chapters makes the book relevant for applied experts working in the domain of forecasting, as the models covered have been published only recently. Experts working in the domain will want to update their skills as traditional models are regularly being outperformed by newer models.Joos is a data scientist, with over five years of industry experience in developing machine learning tools, of which a large part is forecasting models. He currently works at Disneyland Paris where he develops machine learning for a variety of tools. His experience in writing and teaching have motivated him to make this book on advanced forecasting with Python.PART I: Machine Learning for ForecastingChapter 1: Models for ForecastingChapter Goal: Explains the different categories of models that are relevant for forecasting in high level languageNo pages: 10Sub -Topics1.

Clean C++20
Write maintainable, extensible, and durable software with modern C++. This book, updated for the recently released C++20 standard, is a must for every developer, software architect, or team leader who is interested in well-crafted C++ code, and thus also wants to save development costs. If you want to teach yourself about writing better C++ code, Clean C++20 is exactly what you need. It is written for C++ developers of all skill levels and shows by example how to write understandable, flexible, maintainable, and efficient C++ code. Even if you are a seasoned C++ developer, there are nuggets and data points in this book that you will find useful in your work.If you don't take care with your codebase, you can produce a large, messy, and unmaintainable beast in any programming language. However, C++ projects in particular are prone to get messy and tend to slip into a maintenance nightmare. There is lots of C++ code out there that looks as if it was written in the 1980s, completely ignoring principles and practices of well-written and modern C++.It seems that C++ developers have been forgotten by those who preach Software Craftsmanship and Clean Code principles. The web is full of C++ code examples that may be very fast and highly optimized, but whose developers have completely ignored elementary principles of good design and well-written code. This book will explain how to avoid this and how to get the most out of your C++ code. You'll find your coding becomes more efficient and, importantly, more fun.WHAT YOU WILL LEARN* Gain sound principles and rules for clean coding in C++* Carry out test-driven development (TDD)* Better modularize your C++ code base* Discover and apply C++ design patterns and idioms* Write C++ code in both object-oriented and functional programming stylesWHO THIS BOOK IS FORAny C++ developer or software engineer with an interest in producing better code.STEPHAN ROTH is a coach, consultant, and trainer for systems and software engineering with German consultancy company oose Innovative Informatik eG located in Hamburg. Before he joined oose, he worked for many years as a software developer, software architect, and systems engineer in the field of radio reconnaissance and communication intelligence systems. He has developed sophisticated applications, especially in a high-performance system environment, and graphical user interfaces using C++ and other programming languages.

Introduction to Python for Kids
Want to create cool games and apps to impress your friends (or yourself), but not sure where to start? Or, have you tried your hand at programming, but got utterly bored after combing through hundreds of pages of dry text? Then you’ve come to the right place! This book is the perfect blend of education and fun for kids 8 years and above looking to learn the magic of Python, one of the easiest and most powerful programming languages around, all while solving fun puzzles and building your own projects on the way.Yes, there’ll be chapters on the fundamentals of Python, such as variables, numbers, strings, automation with conditions, loops and functions, objects, and files. But, early on in the book you’ll get started with Turtle, a Python package that was custom-made for kids like you. It lets you literally draw and animate on your computer! Every concept will be interspersed with a fun mini project with Turtle, so you’ll never get bored. Once you get the fundamentals down, you’ll dive right into Tkinter and Pygame, more fun Python packages (goodbye theory!) and you’ll learn all about creating apps and games like the ones you see and use every day (bouncing ball, temperature converter, calculator, rock-paper-scissors, and so much more!).There are also four capstone projects at the end of the book that convert everything you’ve learned so far into full-blown apps and games that you can show off to your friends, parents, and even teachers! You’ll be creating a snake game with Turtle, a tic tac toe game with Tkinter, a full-fledged paint app, again with Tkinter, and finally, a classic space shooters game with Pygame (the cherry on top). Every project chapter will be accompanied with the logic behind the game/app and an explanation on how you’ve arrived at the logic. You’ll develop strong problem solving skills that’ll help you create future projects on your own.There are also two chapters dedicated to just creating fun mini projects and puzzles, one of them placed in the middle of the book to give you a welcome break from all the learning. The book ends with an overview on web development with Python and ideas for more fun projects and puzzles you can solve on your own. Become the “most likely to succeed” kid in your grade while having the most fun getting there!WHAT YOU'LL LEARN* Gain a gentle, but thorough introduction into the world of programming and Python* Create programs and solve problems with core Python concepts* Build mini projects and capstone projects (showcase worthy) with Turtle, Tkinter, and Pygame * Develop programming skills while doing the puzzles and activities described in the book WHO THIS BOOK IS FORKids 8 years and above.Aarthi Elumalai is a programmer, educator, entrepreneur, and innovator.

SPS-Programmierung mit dem Raspberry Pi und dem OpenPLC-Projekt
Einführung in die SPS-Programmierung mit dem Open-Source-Projekt auf dem Raspberry Pi und Modbus-Beispiele'mit dem'Arduino Uno und ESP8266Die SPS-Programmierung ist heute in der Industrie und in der Hausauto-mation sehr weit verbreitet. In diesem Buch beschreibt der Autor, wie der Raspberry Pi 4 als SPS eingesetzt werden kann. Angefangen mit der Softwareinstallation auf dem Raspberry Pi und dem SPS-Editor auf dem PC geht es nach einer Beschreibung der Hardware an das Programmieren.Es folgen interessante Beispiele nach IEC 61131-3 in den verschiedenen Programmiersprachen. Ausführlich wird auch erklärt, wie der SPS-Editor benutzt wird und wie die Programme auf den Raspberry Pi geladen und ausgeführt werden. Angefangen mit der Programmierung mit KOP (Kontaktplan) über ST (Structured Control Language) bis zu AS (Special Function Chart) werden alle IEC-Sprachen mit Beispielen behandelt. Diese können auf der Website des Autors heruntergeladen werden.Auch die Vernetzung kommt nicht zu kurz. Der Arduino Uno und der ESP8266 werden als ModbusRTU- bzw. ModbusTCP-Module program-miert, um ZugriŸ auf externe Peripherie zu erhalten. Damit ist es möglich, Sensoren einzulesen und Verbraucher zu schalten. Interessant dürften auch E/A-Schaltungen sein, die dem 24V-Industriestandard entsprechen.Befehlsübersichten für ST und KOP runden das Buch ab.Nach dem Durcharbeiten des Buches ist der Leser in der Lage, eigene SPS-Steuerungen mit dem Raspberry Pi zu verwirklichen.Josef Bernhardt hat sich schon früh mit Elektronik beschäftigt. Mit zwölf Jahren baute er seinen ersten Detektorempfänger. Die ersten Programmiererfahrungen sammelte er in den 80er-Jahren mit dem Commodore VC20. Auch Assemblerprogrammierung auf dem 8088-Prozessor ist ihm nicht fremd. Er kann auf über 30 Jahre Elektronikentwicklung an der Uni Regensburg zurückblicken. Dort war er im Bereich Elektronik- und Softwareentwicklung tätig. Mit der eigenen SMD-Fertigung setzt er auch Elektronikprojekte von Kunden um. Der Spaß an Elekt-ronik und Programmierung sowie sein Interesse an allem Neuen begleiten ihn schon sein ganzes Leben lang.

SAP S/4HANA Embedded Analytics
Imagine you are a business user, consultant, or developer about to enter an SAP S/4HANA implementation project. You are well-versed with SAP’s product portfolio and you know that the preferred reporting option in S/4HANA is embedded analytics. But what exactly is embedded analytics? And how can it be implemented? And who can do it: a business user, a functional consultant specialized in financial or logistics processes? Or does a business intelligence expert or a programmer need to be involved? Good questions!This book will answer these questions, one by one. It will also take you on the same journey that the implementation team needs to follow for every reporting requirement that pops up: start with assessing a more standard option and only move on to a less standard option if the requirement cannot be fulfilled. In consecutive chapters, analytical apps delivered by SAP, apps created using Smart Business Services, and Analytical Queries developed either using tiles or in a development environment are explained in detail with practical examples. The book also explains which option is preferred in which situation. The book covers topics such as in-memory computing, cloud, UX, OData, agile development, and more.Author Freek Keijzer writes from the perspective of an implementation consultant, focusing on functionality that has proven itself useful in the field. Practical examples are abundant, ranging from “codeless” to “hardcore coding.”WHAT YOU WILL LEARN* Know the difference between static reporting and interactive querying on real-time data* Understand which options are available for analytics in SAP S/4HANA* Understand which option to choose in which situation* Know how to implement these optionsWho This Book is ForSAP power users, functional consultants, developersFREEK KEIJZER has a background in science (physics), industry (manufacturing, process industry) and ICT (SAP system integration), holding various project management, people management, and specialist positions. He holds degrees in natural sciences (PhD) and information management (MIM). In 1996, he became involved in an SAP implementation, initially as an R/3 key user, later as internal project leader, interim manager of the support organization, and (international) information manager. Since 2001, he has focused on SAP BI consultancy, working for three consultancy firms and more than 50 clients. His responsibilities as a consultant include product development, team competence development, sales support, and resourcing. Freek's specialties (technical) include SAP Business Intelligence, Hana, NetWeaver, and ERP integration. His roles include project leader, lead consultant, business consultant, (interim) manager, and scrum master.Since 2015, Freek has been a brewer/owner of the Rubelijn craft beer brand.CHAPTER 1: BEFORE THE WORK STARTSCHAPTER GOAL: Miscellaneous intro topics.NO OF PAGES: 40SUB -TOPICS1.
