Deep Belief Nets in C++ and CUDA C: Volume 1
Discover the essential building blocks of the most common forms of deep belief networks. At each step this book provides intuitive motivation, a summary of the most important equations relevant to the topic, and concludes with highly commented code for threaded computation on modern CPUs as well as massive parallel processing on computers with CUDA-capable video display cards. The first of three in a series on C++ and CUDA C deep learning and belief nets, Deep Belief Nets in C++ and CUDA C: Volume 1 shows you how the structure of these elegant models is much closer to that of human brains than traditional neural networks; they have a thought process that is capable of learning abstract concepts built from simpler primitives. As such, you'll see that a typical deep belief net can learn to recognize complex patterns by optimizing millions of parameters, yet this model can still be resistant to overfitting. All the routines and algorithms presented in the book are available in the c ...

Optimizing HPC Applications with Intel Cluster Tools
Optimizing HPC Applications with Intel Cluster Tools takes the reader on a tour of the fast-growing area of high performance computing and the optimization of hybrid programs. These programs typically combine distributed memory and shared memory programming models and use the Message Passing Interface (MPI) and OpenMP for multi-threading to achieve the ultimate goal of high performance at low power consumption on enterprise-class workstations and compute clusters. The book focuses on optimization for clusters consisting of the Intel Xeon processor, but the optimization methodologies also apply to the Intel Xeon Phi coprocessor and heterogeneous clusters mixing both architectures. Besides the tutorial and reference content, the authors address and refute many myths and misconceptions surrounding the topic. The text is augmented and enriched by descriptions of real-life situations. ...

PhoneGap for Enterprise
This book covers the necessary concepts you'll need to build useful, rich, secure enterprise apps for mobile devices, and also explains portions of an example enterprise app development so that you have a working demonstration of the concepts in the book. The book focuses heavily on security concepts such as authorization, SSL and certificates, source code protection, local data store encryption, and so on, as ensuring a secure channel of communication between the user and the enterprise servers is critical. The book explores the entire app's design, covering the data model and business logic you'll use for your app. It then moves on to cover how to build middle-tier communication between the middle tier and the mobile device, handling application and network events (such as a network going offline), and culminates by showing you how to work with various rich presentation technologies. ...

Text Mining with R
Much of the data available today is unstructured and text-heavy, making it challenging for analysts to apply their usual data wrangling and visualization tools. With this practical book, you'll explore text-mining techniques with tidytext, a package that authors Julia Silge and David Robinson developed using the tidy principles behind R packages like ggraph and dplyr. You'll learn how tidytext and other tidy tools in R can make text analysis easier and more effective. The authors demonstrate how treating text as data frames enables you to manipulate, summarize, and visualize characteristics of text. You'll also learn how to integrate natural language processing (NLP) into effective workflows. Practical code examples and data explorations will help you generate real insights from literature, news, and social media. Learn how to apply the tidy text format to NLP; Use sentiment analysis to mine the emotional content of text; Identify a document's most important terms with frequency ...
