SQL Primer: An Accelerated Introduction to SQL Basics-Rahul Batra2018-10-27
Build a core level of competency in SQL so you can recognize the parts of queries and write simple SQL statements. SQL knowledge is essential for anyone involved in programming, data science, and data management. This book covers features of SQL that are standardized and common across most database vendors. You will gain a base of knowledge that will prepare you to go deeper into the specifics of any database product you might encounter. Examples in the book are worked in PostgreSQL and SQLite, but the bulk of the examples are platform agnostic and will work on any database platform supporting SQL. Early in the book you learn about table design, the importance of keys as row identifiers, and essential query operations. You then move into more advanced topics such as grouping and summarizing, creating calculated fields, joining data from multiple tables when it makes business sense to do so, and more. Throughout the book, you are exposed to a set-based approach to the language and are provided a good grounding in subtle but important topics such as the effects of null value on query results. With the explosion of data science, SQL has regained its prominence as a top skill to have for technologists and decision makers worldwide. SQL Primer will guide you from the very basics of SQL through to the mainstream features you need to have a solid, working knowledge of this important, data-oriented language.
【12】Deep speech 2 End-to-end speech recognition in english and mandarin.pdf2019-08-26
We show that an end-to-end deep learning approach can be used to recognize either English or Mandarin Chinese speech—two vastly different languages. Because it replaces entire pipelines of hand-engineered components with neural networks, end-to-end learning allows us to handle a diverse variety of speech including noisy environments, accents and different languages. Key to our approach is our application of HPC techniques, resulting in a 7x speedup over our previous system . Because of this efficiency, experiments that previously took weeks now run in days. This enables us to iterate more quickly to identify superior architectures and algorithms. As a result, in several cases, our system is competitive with the transcription of human workers when benchmarked on standard datasets. Finally, using a technique called Batch Dispatch with GPUs in the data center, we show that our system can be inexpensively deployed in an online setting, delivering low latency when serving users at scale.

3-D convolutional neural networks (3-D-convNets) have been very recently proposed for action recognition in videos, and promising results are achieved. However, existing 3- D-convNets has two “artificial” requirements that may reduce the quality of video analysis: 1) It requires a fixed-sized (e.g., 112×112) input video; and 2)most of the 3-D-convNets require a fixed-length input (i.e., video shots with fixed number of frames). To tackle these issues, we propose an end-to-end pipeline named Two-stream 3-D-convNet Fusion, which can recognize human actions in videos of arbitrary size and length using multiple features. Specifically, we decompose a video into spatial and temporal shots. By taking a sequence of shots as input, each stream is implemented using a spatial temporal pyramid pooling (STPP) convNet with a long short-term memory (LSTM) or CNN-E model, softmax scores of which are combined by a late fusion.We devise the STPP convNet to extract equal-dimensional descriptions for each variable-size shot, andwe adopt theLSTM/CNN-Emodel to learn a global description for the input video using these time-varying descriptions. With these advantages, our method should improve all 3-D CNN-based video analysis methods. We empirically evaluate our method for action recognition in videos and the experimental results show that our method outperforms the state-of-the-art methods (both 2-D and 3-D based) on three standard benchmark datasets (UCF101, HMDB51 and ACT datasets).
Diskeeper 2008 v12.0.759.02010-07-04
October 16, 2007 Diskeeper[R] 2008 (Build 758) TABLE OF CONTENTS ================= A. PLATFORMS AND OPERATING SYSTEM VERSIONS SUPPORTED B. OVERVIEW OF DISKEEPER 2008 C. CHANGES DISKEEPER 2008 D. CHANGES IN THIS RELEASE E. KNOWN ISSUES IN THIS RELEASE F. KNOWN INCOMPATIBILITIES G. INSTALLING DISKEEPER H. UNINSTALLING DISKEEPER I. TABLE OF SUPPORTED OPERATING SYSTEMS ----------------------------------------------------------------- A. PLATFORMS AND WINDOWS[R] VERSIONS SUPPORTED =============================================== Diskeeper runs on the Intel[R] x86 platform (including compatible CPUs from other manufacturers) running Windows Vista[TM], Windows Home Server, Windows Server[TM] 2003, Windows XP, or Windows 2000. Note that Windows 2000 systems must be running Service Pack 3 or higher. The Windows versions supported vary by Diskeeper edition. See the Table of Supported Operating Systems later in this document for a chart of the different Diskeeper editions and the Windows versions each supports. Note that x64 versions of Diskeeper will only install on x64 editions of Windows. B. OVERVIEW OF DISKEEPER 2008 ============================== For over a decade, Diskeeper has led the way in Windows system defragmentation technology, and Diskeeper 2008 continues with the tradition of true Set It and Forget It[R] performance enhancement that is a hallmark of the Diskeeper name. Whether you抳e used Diskeeper before or not, you may already be familiar with some of its features, but Diskeeper 2008 adds refinements to these features, and a number of other core enhancements. New users will find Diskeeper to be easy to use, yet comprehensive in its capabilities. Experienced Diskeeper users will recognize familiar features, but see improvements in Diskeeper (and their system) performance. This list summarizes the most important features in the various editions. More information about each of these features is available in the Diskeeper Help system: Fully Automatic Operation ------------------------- Diskeeper is designed to operate without your intervention. Simply install Diskeeper, then sit back and let it take care of the details. Of course, you can also run Diskeeper manually. (But you probably have better things to do with your time. That抯 what Automatic Defragmentation with InvisiTasking is for!) Diskeeper Family of Products ---------------------------- The Diskeeper family of products offers specialized automatic defragmentation of Windows operating systems ranging from Windows 2000 through Windows XP, Windows Vista, Windows Home Server, and Windows Server 2003 Datacenter. Descriptive Console Interface ----------------------------- The Diskeeper console provides an intuitive and informative defragmentation experience. Common commands are grouped together in the Quick Launch pane, and a group of tabbed panes show you a wide variety of information. Diskeeper shows you the condition of your disks, and provides suggestions for improving or maintaining your disks. Performance and Volume Health Analysis -------------------------------------- Diskeeper collects and displays data regarding the performance and overall health of your volumes in the Dashboard tab. This information allows you to be more proactive in the management and maintenance of your computers. I-FAAST[R] (Intelligent File Access Acceleration Technology) ------------------------------------------------------------ Intelligent File Access Acceleration Sequencing Technology (I-FAAST) improves file access/creation by up to 80% (average 10%-20%) above and beyond the improvement provided by defragmentation alone. This is the first industry implementation of "Disk Performance Calibration", the modern evolution of the outdated and inconclusive disk optimization strategies of the past. Frag Shield[TM] --------------- One situation that can impair the performance and reliability of your computer is fragmentation of the Master File Table (MFT) on NTFS volumes and your paging files. Since the operating system relies heavily on the MFT and paging file, the effect of fragmentation is often much greater than when a normal file is fragmented. The Frag Shield feature keeps your MFTs defragmented automatically, and monitors paging file usage and makes suggestions to keep it performing at its best, too. Terabyte Volume Engine[TM] -------------------------- A Diskeeper exclusive, the Terabyte Volume Engine (TVE) is designed to efficiently defragment extremely large (larger than 60 GB) volumes. This feature is available in selected Diskeeper editions. Boot-Time Defragmentation ------------------------- Defragment files at boot-time that cannot be moved safely when Windows is running. Exclusion Lists --------------- Diskeeper exclusion lists allow you to specify files and directories that will not be allowed to be processed by Diskeeper. Event Logging ------------- Diskeeper records information about its activity in two ways. First, general information about previously-run defragmentation job is shown in the Log tab within the Diskeeper console. Additional information can also be stored in a log file. A wide variety of information can be saved for future reference. Simultaneous Analysis or Defragmentation Operations --------------------------------------------------- You can analyze and/or defragment more than one disk volume at a time. Different Diskeeper editions support different numbers of simultaneous operations. Command Line Operation ---------------------- You can use commands from the Windows Command Prompt or a batch file to control Diskeeper. Group Policy Support -------------------- Diskeeper can be configured network-wide with the Group Policy Editor provided with Windows 2000 Server, Windows Server 2003, Windows XP, and Windows Vista. C. CHANGES IN DISKEEPER 2008 ============================= Here is a summary of what抯 new in this version: o Complete file and free space defragmentation in the most extreme of conditions Diskeeper 2008 introduces the most powerful defragmentation engine ever developed. Even if your systems only have a percent or two of free space left available or a file in millions of fragments, Diskeeper can restore lost performance and save the applications reliant on those files from major reliability concerns. o Core "Defragmentation Intelligence" Enhancements The brains behind defragmentation is the Diskeeper "controller丒 which has been re-designed to deliver performance benefit faster and more efficiently. The controller抯 job is to detect various volume and system conditions and choose the most effective algorithm from the vast arsenal of Diskeeper defragmentation engines. o Frag Shield 2.0 Frag Shield is the first and only technology to prevent system file fragmentation gets better. No more need to run a manual and resource-intensive process. Frag Shield抯 MFT fragmentation prevention technology is now fully automatic and re-written to operate invisibly using InvisiTasking technology. o Volume Shadow Copy Service (VSS) Compatibility Mode Defragmenting VSS-enabled volumes has been complicated, until now. Diskeeper 2008 eliminates the need to choose between the benefits of VSS and defragmentation. The new VSS-compatible mode in Diskeeper 2008 affords you the ability to leverage the data protection of VSS and the performance and reliability of Diskeeper defragmentation. o Disk Performance Analyzer for Networks (DPAN) The award winning network analysis product from Diskeeper Corporation with over 30,000 downloads is now integrated into Diskeeper Administrator. In Diskeeper 2008 the clientless performance analysis technology gets a full update and tight integration with Diskeeper Administrator抯 industry-pioneering performance management functionality. Now you can get real-time performance metrics with high-level visual graphs and detailed fragmentation data on-demand or e-mailed automatically. o A special Diskeeper Edition for Windows Home Server (WHS) Diskeeper 2008 HomeServer is the only defragmentation solution specifically designed for Windows Home Server operating system. Diskeeper HomeServer provides a snap-in to the new WHS console, supporting full remote management and configuration capability from any PC in a SOHO network. o ...and of course the InvisiTasking technology continues as the underlying technology in Diskeeper. InvisiTasking is not merely an enhancement to existing features; it allows the Set It and Forget It tradition of Diskeeper to evolve to a new level of autonomous operation that provides real-time defragmentation of files without any administrative effort. D. CHANGES IN THIS RELEASE =========================== 1. This is the initial public release of Diskeeper 2008. E. KNOWN ISSUES IN THIS RELEASE ================================ 1. Although Diskeeper itself is fully compliant with Section 508 (accessibility) standards, 508 compliance is not yet fully implemented into the Diskeeper installation procedure. 2. Some of the Diskeeper installation dialogs do not display correctly on computers using the High Contrast Black display setting under the Windows Accessibility Options. Note, however, the Diskeeper console does display correctly on these computers. 3. When running Diskeeper from the Windows command prompt, the /d parameter is not an optional parameter; it is required. 4. Note that these files are not removed when Diskeeper is uninstalled: Productname.msi (for example, Diskeeper 2008 Server.msi) DKDesktopShortcut_A4ED7F98B2A54A06855C7E8804E8460E.exe These files are open during the uninstallation process, but they can safely be deleted afterwards. 5. When clicking links within Diskeeper that open web browsers, Diskeeper typically launches whichever browser has been set as the system default. However, on Windows Vista and Windows Server 2003, Internet Explorer is opened, regardless of the system default setting. 6. Under rare circumstances, an error message stating "Unhandled Exception Error 0x0000005 Press "ESC" to reboot system" may be displayed when a Boot-Time defragmentation operation is in progress. This message is displayed when the Boot-Time defragmentation engine does not receive the expected data from the operating system. If this occurs, the Boot-Time engines safely stop any further processing, to ensure the integrity of your system. 7. When installing Diskeeper 2008 over an existing Diskeeper 2007 system, in some cases the Diskeeper 2007 does not stop correctly. This can result in long completion times for the installation operation, or a crash of the Diskeeper Service. The installation will complete successfully after the Diskeeper 2007 Service is stopped. F. KNOWN INCOMPATIBILITIES =========================== 1. Diskeeper will not run on disk volumes that are locked by utilities such as CHKDSK or Scandisk. 2. The Hercules Terminator AGP 128/3D "GLH" 8MB also does not appear to display the full Boot-Time dialog, and thus appears to hang when the "Pause to view screen after defragmentation" option in the Diskeeper Boot-Time Properties as been enabled. 3. The keyboard functions during a Boot-Time Defragmentation job do not work on all combinations of hardware, HAL (hardware abstraction layer), and operating systems. We are working to provide keyboard access from the greatest combination of these elements, but if your system does not respond to the keyboard functions during a boot-time, please report the hardware configuration and full operating system version to Diskeeper Corporation Technical Support at this address: (firstname.lastname@example.org). Providing this information may help us determine why certain combinations of hardware and software cannot access the keyboard functions during Boot-Time Defragmentation. 4. Diskeeper is compatible with Roxio GoBack. Note, however, that you should add the "gobackio.bin" file to the Diskeeper exclusion list. After doing so, should be no problems running GoBack along with Diskeeper. 5. The free space figures displayed in the Diskeeper MMC snap-in may not match those shown in the Diskeeper report view if you are running Norton Protect. 6. Problems have been noted when Diskeeper is running on systems that are also running Norton Internet Security Package with the Anti-Virus component enabled. Enabling port 135 on the affected computer corrects the problem. 7. If you are running Diskeeper on a CITRIX server, exclude the "TAB.DLL" and "DkTabProvider.DLL from the CITRIX Memory Optimizer feature. If these files are not excluded, the CITRIX Memory Optimizer will flag them as being "tampered", when in fact they are not. G. INSTALLING DISKEEPER ======================== Note: Make sure you are logged onto an account that is a member of the Administrators group. Diskeeper is available either as a downloaded self-extracting compressed file, or on CD-ROM. The following instructions apply to both formats. Follow these steps to install Diskeeper: The Diskeeper installation is typically fast and simple. Here are the basic steps: 1. Insert the Diskeeper CD-ROM into the appropriate drive on your computer. (If you are installing from a downloaded file, double-click the file you downloaded.) 2. Follow the screens displayed, answering the questions asked as prompted. For more details about installing Diskeeper, see the "Diskeeper Installation" chapter in the Diskeeper User's Manual. H. UNINSTALLING DISKEEPER ========================== To uninstall Diskeeper, you must be logged into an account that is a member of the Administrators group. Follow these steps to completely remove and uninstall Diskeeper from your computer. Note that the controls may have slightly different names, depending on your version of Windows: 1. From Control Panel, double click "Add/Remove Programs". 2. Highlight the Diskeeper entry. 3. Click Remove. This removes the Diskeeper program files from your computer. In most cases, the Diskeeper installation directory will not be removed. 4. During the uninstall process, the Windows Disk Defragmenter is restored to the state it was in before Diskeeper was installed. 5. Manually delete the Diskeeper installation directory if it exists. Note: If the MMC has been installed on your computer, it will not be removed when Diskeeper is uninstalled. I.

HMM-based Script Identification for OCR2018-09-10
HMM-based Script Identification for OCR While current OCR systems are able to recognize text in an increasing number of scripts and languages, typically they still need to be told in advance what those scripts and languages are. We propose an approach that repurposes the same HMM-based system used for OCR to the task of script/language ID, by replacing character labels with script class labels. We apply it in a multi-pass overall OCR process which achieves “universal” OCR over 54 tested languages in 18 distinct scripts, over a wide variety of typefaces in each. For comparison we also consider a brute-force ap- proach, wherein a singe HMM-based OCR system is trained to recognize all considered scripts. Results are presented on a large and diverse evaluation set extracted from book im- ages, both for script identification accuracy and for overall OCR accuracy. On this evaluation data, the script ID sys- tem provided a script ID error rate of 1.73% for 18 distinct scripts. The end-to-end OCR system with the script ID sys- tem achieved a character error rate of 4.05%, an increase of 0.77% over the case where the languages are known a priori.
The World Wide Web has been credited with bringing the Internet to the masses. The Internet was previously the stomping ground of academics and a small, elite group of computer professionals, mostly UNIX programmers and other oddball types, running obscure commands like ftp and finger, archie and telnet, and so on. With the arrival of graphical browsers for the Web, the Internet suddenly exploded. Anyone could find things on the Web. You didn't need to be "in the know" anymore--you just needed to be properly networked. Equipped with Netscape Navigator or Internet Explorer or any other browser, everyone can now explore the Internet freely. But graphical browsers can be limiting. The very interactivity that makes them the ideal interface for the Internet also makes them cumbersome when you want to automate a task. It's analogous to editing a document by hand when you'd like to write a script to do the work for you. Graphical browsers require you to navigate the Web manually. In an effort to diminish the amount of tedious pointing-and-clicking you do with your browser, this book shows you how to liberate yourself from the confines of your browser. Web Client Programming with Perl is a behind-the-scenes look at how your web browser interacts with web servers. Readers of this book will learn how the Web works and how to write software that is more flexible, dynamic, and powerful than the typical web browser. The goal here is not to rewrite the browser, but to give you the ability to retrieve, manipulate, and redistribute web-based information in an automated fashion. Who This Book Is For I like to think that this book is for everyone. But since that's a bit of an exaggeration, let's try to identify who might really enjoy this book. This book is for software developers who want to expand into a new market niche. It provides proof-of-concept examples and a compilation of web-related technical data. This book is for web administrators who maintain large amounts of data. Administrators can replace manual maintenance tasks with web robots to detect and correct problems with web sites. Robots perform tasks more accurately and quickly than human hands. But to be honest, the audience that's closest to my heart is that of computer enthusiasts, tinkerers, and motivated students, who can use this book to satisfy their curiosity about how the Web works and how to make it work for them. My editor often talks about when she first learned UNIX scripting and how it opened a world of automation for her. When you learn how to write scripts, you realize that there's very little that you can't do within that universe. With this book, you can extend that confidence to the Web. If this book is successful, then for almost any web-related task you'll find yourself thinking, "Hey, I could write a script to do that!" Unfortunately, we can't teach you everything. There are a few things that we assume that you are already familiar with: G The concept of client/server network applications and TCP/IP. G How the Internet works, and how to access it. G The Perl language. Perl was chosen as the language for examples in this book due to its ability to hide complexity. Instead of dealing with C's data structures and low-level system calls, Perl introduces higher-level functions and a straightforward way of defining and using data. If you aren't already familiar with Perl, I recommend Learning Perl by Randal Schwartz, and Programming Perl (popularly known as "The Camel Book") by Larry Wall, Tom Christiansen, and Randal Schwartz. Both of these books are published by O'Reilly & Associates, Inc. There are other fine Perl books as well. Check out http://www.perl.com for the latest book critiques. Is This Book for You? Some of you already know why you picked up this book. But others may just have a nagging feeling that it's something useful to know, though you may not be entirely sure why. At the risk of seeming self-serving, let me suggest some ways in which this book may be helpful: G Some people just like to know how things tick. If you like to think the Web is magic, fine--but there are many who don't like to get into a car without knowing what's under the hood. For those of you who desire a better technical understanding of the Web, this book demystifies the web protocol and the browser/server interaction. G Some people hate to waste even a minute of time. Given the choice between repeating an action over and over for an hour, or writing a script to automate it, these people will choose the script every time. Call it productivity or just stubbornness--the effect is the same. Through web automation, much time can be saved. Repetitive tasks, like tracking packages or stock prices, can be relegated to a web robot, leaving the user free to perform more fruitful activities (like eating lunch). G If you understand your current web environment, you are more likely to recognize areas that can be improved. Instead of waiting for solutions to show up in the marketplace, you can take an active role in shaping the future direction of your own web technology. You can develop your own specialized solutions to fit specific problems. G In today's frenzied high-tech world, knowledge isn't just power, it's money. A reasonable understanding of HTTP looks nice on the resume when you're competing for software contracts, consulting work, and jobs.
