Through a series of recent breakthroughs, deep learning has boosted the entire field of machine learning. Now, even programmers who know close to nothing about this technology can use simple, efficient tools to implement programs capable of learning from data. This practical book shows you how. By using concrete examples, minimal theory, and two production-ready Python frameworks—Scikit-Learn and TensorFlow—author Aurélien Géron helps you gain an intuitive understanding of the concepts and tools for building intelligent systems. You’ll learn a range of techniques, starting with simple linear regression and progressing to deep neural networks. With exercises in each chapter to help you apply what you’ve learned, all you need is programming experience to get started. * Explore the machine learning landscape, particularly neural nets * Use Scikit-Learn to track an example machine-learning project end-to-end * Explore several training models, including support vector machines, decision trees, random forests, and ensemble methods * Use the TensorFlow library to build and train neural nets * Dive into neural net architectures, including convolutional nets, recurrent nets, and deep reinforcement learning * Learn techniques for training and scaling deep neural nets

安装python 安装wxpython 执行python python_repeater.py 它很简单，但复读mp3是够用的。 TAB一键复读，很棒。

好不好用不知道。郑码越来越不好用了。极点郑码bug比较多，不知道现在有多少改进。

真不知道为什么看这本书的人很少。这是一手UML资料啊。人们还是更喜欢看二手的东西。真不明白是为什么。不明白啊。

小小输入法，但修改了郑码的码表，采用郑码66版。

极点郑码66版编码，是一个文本文件，包括郑码6.6版的所有单字和词的编码。

郑码输入法，很好的输入法。能满足我的需求。以前一直在找好的郑码输入法，现在找到了。应该是目前为止最好的了。

讲在android中如何显示和处理图像、播放声音和视频。

我觉得是Android的入门好书，讲了基本的东西，当然也只是基本的东西。

DESIGN PATTERNS ARE class- and method-level solutions to common problems in object-oriented design. If you’re an intermediate-level Java programmer who wants to become advanced or an advancedlevel Java programmer who hasn’t yet studied design patterns, this book is for you. Design Patterns in Java™ takes a workbook approach. Each chapter focuses on a particular pattern. In addition to explaining the pattern, the chapter includes a number of challenges, each asking you to explain something or to develop code that solves a problem. We strongly urge you to stop and work through the challenges rather than try to read this book straight through. You’ll learn more by putting in the work to do the challenges, even if it’s only a chapter or two a week.

To this day, enterprise message queuing is a concept that is not well understood by most software developers. Commercial message-oriented middleware (MOM) did not help to encourage adoption of the process; most of the MOMs on the market were closed source, were costly to buy and support, and required trained system administrators for proper installation. ActiveMQ was developed to provide an open source alternative: its central theme is to put the power in the hands of developers. To date, the ActiveMQ project has been successful in this endeavor by creating a MOM that is easy to install, administer, and utilize, while providing a large number of unique features. Today, six or seven years after ActiveMQ was originally created, it’s surprising how far and widely it is being used. ActiveMQ is a crucial component in many applications. Used by small businesses and very large enterprises alike, ActiveMQ is deployed throughout a wide variety of industries around the world including manufacturing, government, retail, healthcare, finance, military, telecom, and many more. The versatility of not only ActiveMQ but also event-based systems has appealed to a very large audience of users and that appeal continues to grow. In writing a book about ActiveMQ, our intent was to provide a comprehensive guide for its features and how to use them. Although ActiveMQ implements the JMS specification, which has not moved in many years, ActiveMQ provides many features beyond this spec and it has not stopped innovating. As is always the case, authoring a book about software is a game of chase; as the software evolves, so must the book that is still being written. We did our best to keep this book up to date with ActiveMQ 5.4.1. We hope that, by reading this book, you will come to appreciate not only ActiveMQ but the concepts surrounding event-based systems. After all, some of the largest systems in the world are designed using events and message queuing.

This book does not aim to make the reader an expert in digital television (which the author himself is not). Rather, its purpose is to describe and explain, as simply and as completely as possible, the various aspects of the very complex problems that had to be solved in order to define reliable standards for broadcasting digital pictures to the consumer, and the solutions chosen for the European DVB system (Digital Video Broadcasting) based on the international MPEG-2 compression standard. The book is intended for readers with a background in electronics and some knowledge of conventional analog television (a reminder of the basic principles of existing television standards is presented for those who require it) and for those with a basic digital background. The main goal is to enable readers to understand the principles of this new technology, to have a relatively global perspective on it, and, if they wish, to investigate further any particular aspect by reading more specialized and more detailed books. At the end, there is a short bibliography and a glossary of abbreviations and expressions which will help readers to access some of these references. For ease of understanding, after a general presentation of the problem, the order in which the main aspects of digital television broadcast standards are described follows the logical progression of the signal processing steps on the transmitter side—from raw digitization used in TV studios to source coding (MPEG-2 compression and multiplexing), and on to channel coding (from forward error correction to RF modulation). JPEG and MPEG-1 “predecessor” standards of MPEG-2 are also described, as MPEG-2 uses the same basic principles.
