Generatives Deep Learning
Generative Modelle haben sich zu einem der spannendsten Themenbereiche der Künstlichen Intelligenz entwickelt: Mit generativem Deep Learning ist es inzwischen möglich, einer Maschine das Malen, Schreiben oder auch das Komponieren von Musik beizubringen – kreative Fähigkeiten, die bisher dem Menschen vorbehalten waren. Mit diesem praxisnahen Buch können Data Scientists einige der eindrucksvollsten generativen Deep-Learning-Modelle nachbilden, wie z.B. Generative Adversarial Networks (GANs), Variational Autoencoder (VAEs), Encoder-Decoder- sowie World-Modelle. David Foster vermittelt zunächst die Grundlagen des Deep Learning mit Keras und veranschaulicht die Funktionsweise jeder Methode, bevor er zu einigen der modernsten Algorithmen auf diesem Gebiet vorstößt. Die zahlreichen praktischen Beispiele und Tipps helfen Ihnen herauszufinden, wie Ihre Modelle noch effizienter lernen und noch kreativer werden können. - Entdecken Sie, wie Variational Autoencoder den Gesichtsausdruck auf Fotos verändern können - Erstellen Sie praktische GAN-Beispiele von Grund auf und nutzen Sie CycleGAN zur Stilübertragung und MuseGAN zum Generieren von Musik - Verwenden Sie rekurrente generative Modelle, um Text zu erzeugen, und lernen Sie, wie Sie diese Modelle mit dem Attention-Mechanismus verbessern können - Erfahren Sie, wie generatives Deep Learning Agenten dabei unterstützen kann, Aufgaben im Rahmen des Reinforcement Learning zu erfüllen - Lernen Sie die Architektur von Transformern (BERT, GPT-2) und Bilderzeugungsmodellen wie ProGAN und StyleGAN kennen "Dieses Buch ist eine leicht zugängliche Einführung in das Deep-Learning-Toolkit für generatives Modellieren. Wenn Sie ein kreativer Praktiker sind, der es liebt, an Code zu basteln, und Deep Learning für eigene Aufgaben nutzen möchte, dann ist dieses Buch genau das Richtige für Sie." — David Ha, Research Scientist bei Google Brain

Algorithm Concept for Crash Detection in Passenger Cars
State-of-the-art airbag algorithms make a decision to fire restraint systems in a crash by evaluating the deceleration of the entire vehicle during the single events of the accident. In order to meet the ever increasing requirements of consumer test organizations and global legislators, a detailed knowledge of the nature and direction of the crash would be of great benefit. The algorithms used in current vehicles can only do this to a limited extent. André Leschke presents a completely different algorithm concept to solve these problems. In addition to vehicle deceleration, the chronological sequence of an accident and the associated local and temporal destruction of the vehicle are possible indicators for an accident’s severity. About the Author: Dr. André Leschke has earned his doctoral degree from Tor-Vergata University of Rome, Italy. Currently, he is working as head of a team of vehicle safety developers in the German automotive industry.

PostgreSQL Configuration
Obtain all the skills you need to configure and manage a PostgreSQL database. In this book you will begin by installing and configuring PostgreSQL on a server by focusing on system-level parameter settings before installation. You will also look at key post-installation steps to avoid issues in the future. The basic configuration of PostgreSQL is tuned for compatibility rather than performance. Keeping this in mind, you will fine-tune your PostgreSQL parameters based on your environment and application behavior. You will then get tips to improve database monitoring and maintenance followed by database security for handling sensitive data in PostgreSQL.Every system containing valuable data needs to be backed-up regularly. PostgreSQL follows a simple back-up procedure and provides fundamental approaches to back up your data. You will go through these approaches and choose the right one based on your environment. Running your application with limited resources can be tricky. To achieve this you will implement a pooling mechanism for your PostgreSQL instances to connect to other databases. Finally, you will take a look at some basic errors faced while working with PostgreSQL and learn to resolve them in the quickest manner.WHAT YOU WILL LEARN* Configure PostgreSQL for performanceMonitor and maintain PostgreSQL instances * Implement a backup strategy for your dataResolve errors faced while using PostgreSQLWHO THIS BOOK IS FORReaders with basic knowledge of PostgreSQL who wish to implement key solutions based on their environment.Baji Shaik is a database administrator and developer.

He is a database migration expert and has developed many successful database solutions addressing challenging business requirements for moving databases from on-premises to AWS Cloud using multiple AWS services. Baji has organized a number of PostgreSQL meet-ups and maintains his own technical blog, where he likes to share his knowledge with the community. He co-authored Beginning PostgreSQL on the Cloud, released in March 2018.CHAPTER 01. INSTALLING POSTGRESQL THE RIGHT WAY! (10 PAGES)There are multiple ways you can install PostgreSQL on a server. This chapter will talk about the best ways to do so, focusing on system-level parameter settings before installation as a prerequisite and also post-installation steps to avoid issues in the future.CHAPTER 02. CONFIGURING YOUR DATABASE FOR PERFORMANCE (20 PAGES)PostgreSQL ships with a basic configuration tuned for wide compatibility rather than performance. Although the default settings of PostgreSQL are viable, it is always recommended to tune some basic parameters based on your environment and application behavior.CHAPTER 03. ENABLE LOGGING OF YOUR DATABASE (15 PAGES)Logging is key when you troubleshoot issues of PostgreSQL for security and performance to find out the trends. Default PostgreSQL configuration comes with very minimal logging and it is not always enough to troubleshoot the issues. So, this chapter will explain how to set logging and consequences of high logging and how to deal with it.CHAPTER 04. MONITORING POSTGRESQL INSTANCES (15 PAGES)Good monitoring is a symbol of a peaceful life for an administrator. If you set up monitoring of your databases to alert you whenever an issue comes up, then you need not worry about keeping an eye at your databases' health. This chapter will show you ways to monitor PostgreSQL instances.CHAPTER 05. EXECUTE MAINTENANCE (15 PAGES)Why do you need maintenance? What would you get from it? when do decide "it's time for maintenance"? How do you do it? Is there any way I can improve my maintenance time? This chapter will shed some light on all these questions.CHAPTER 06. SECURING DATABASES (15 PAGES)Security is one of the major concerns for storing sensitive data. It could be one of the reasons customers change their database engines. So, this chapter will talk about how best you can secure your data in PostgreSQL.CHAPTER 07. BACKUP AND RESTORE BEST PRACTICES (15 PAGES)For critical data systems, backup and restore is a very important consideration. However, it's very important to know what factors you should consider before you implement a backup strategy and how to implement one. This chapter talks about developing backup procedures for critical/non-critical data systems and quick restore procedures as well.CHAPTER 08. HIGH AVAILABILITY PROCEDURES (15 PAGES)You may come across some situations where you cannot make your primary working with-in your affordable time window. What do you do in that scenario? Implementing High Availability is always the best practice for such critical applications. This chapter talks about HA implementation and open source tools that can be used with PostgreSQL to implement the same.CHAPTER 09. IMPLEMENTING POOLER (15 PAGES)While running your application with limited resources, then it is highly recommended to use Pooling to connect the database. Performance of a database depends on the parallel connections that it can allow. Huge connections to a database in parallel degrades the database performance. This chapter will teach you to implement a pooler mechanism for your PostgreSQL instances.CHAPTER 10. BASIC ERRORS AND HANDY QUERIES (15 PAGES)Working with PostgreSQL, there are bound to be some errors you might face that takes a lot of time to resolve. And, some times you might need some queries which are based on catalogs to fetch the information. This chapter talks about some of these errors and their resolution so that it can save some time for administrators followed by handy queries to help them perform their daily duties.

Living with Computers
The computing technology on which we are now so dependent has risen to its position of ascendency so rapidly that few of us have had the opportunity to take a step back and wonder where we are headed. This book urges us to do so.Taking a big-picture perspective on digital technology, Living with Computers leads the reader on a whistle-stop tour of the history of information and information technology. This journey culminates in a deep exploration into the meaning and role of computers in our lives, and what this experience might possibly mean for the future of human society – and the very existence of humanity itself.In the face of the transformative power of computing, this book provokes us to ask big questions. If computers become integrated into our bodies, merging with the information processing of our very DNA, will computing help to shape the evolution of biological life? If artificial intelligence advances beyond the abilities of the human brain, will this overturn our anthropocentrism and lead to a new view of reality? Will we control the computers of the future, or will they control us?These questions can be discomforting, yet they cannot be ignored. This book argues that it is time to reshape our definition of our species in the context of our interaction with computing. For although such science-fiction scenarios are not likely to happen any time soon – and may, in fact, never happen – it is nevertheless vital to consider these issues now if we wish to have any influence over whatever is to come. So, humans, let’s confront our possible destiny!JAMES W. CORTADA is a Senior Research Fellow at the Charles Babbage Institute at the University of Minnesota.

Software-Engineering - kompakt
Von zentraler Bedeutung für das Software-Engineering ist der Software-Lebenszyklus. Gemeint ist damit der gesamte Prozess, der zur Erstellung und Erhaltung eines Softwaresystems führt. Sowohl in traditionellen als auch in agilen Softwareerstellungsprozessen läuft dieser Lebenszyklus ab. Bewährt hat sich in der Praxis die Einteilung in sogenannte Phasen, denen die Gliederung folgt.Nach einer kurzen Einführung werden in Kapitel 2 vorab phasenübergreifende Verfahren wie divergierende Vorgehensmodelle und Projektmanagement besprochen. Kapitel 3 behandelt die Planungsphase; Kapitel 4 ist dem Requirements-Engineering gewidmet, bei dem die Software-Anforderungen kreativ konstruiert, analysiert und – traditionell oder agil – dokumentiert werden. In Kapitel 5 folgt die Besprechung der Verfahren für die Designphase der Software. Hier wird hinterfragt, wie gute Software-Architekturen Erfolg versprechend erdacht, mit der UML-Notation geeignet modelliert und in späteren Projekten wiederverwendet werden können. Kapitel 6 widmet sich der Test- und Abnahmephase und damit den wichtigen Qualitätssicherungsfragen. Abschließend wird in Kapitel 7 die Wartung – zur wirksamen Erhaltung von Softwaresystemen – erklärt.Anfänger erhalten eine schnelle Orientierung und kompaktes, fundiertes Grundwissen. Fortgeschrittene Leser finden hier ein aktuelles, gut strukturiertes Nachschlagewerk.
