Computers. Text Mining, Scraping and Sentiment Analysis with R. Are you an advanced R user, looking to expand your R toolbox? Are you interested in social media sentiment analysis? Do you want to learn how you can get and use Twitter data for your R analysis? Do you want to learn how you can systematically find related words (keywords) to a search term using Twitter and R? Are you interested in creating visualizations like wordclouds out of text data? Do you want to learn which R packages you can use for web scraping and text analysis purposes? If YES came to your mind to some of those points – this course might be tailored towards your needs! This course will teach you anything you need to know about how to handle social media data in R.
During this course we will take a walk through the whole text analysis process of Twitter data. At first you will learn which packages are available for social media analysis. You will learn how to scrape social media (Twitter) data and get it into your R session. What R you waiting for? Martin.

In recent years, machine learning has made a lot of progress in different application domains such as computer vision and speech recognition. Most of this success has been achieved by scaling up existing methods to leverage the information contained in big data. In particular, models tailored for sequential prediction have shown strong results in challenging natural language problems such as language modeling. With the recent success of deep learning, one can ask how far are we from developing a real artificial intelligence as shown in science fiction movies. In our recent work, we show that certain simple sequential patterns cannot be learned by these popular deep learning approaches. We propose a novel sequence prediction approach which has the capability to learn these simple concepts. The model includes a memory structure that is learned to operate in a way to solve the training tasks. In the paper, we also demonstrate what a non-trivial example of what the model could learn.
Operating Systems: Three Easy Pieces. Blog: Why Textbooks Should Be Free Quick: Free Book Chapters - Buy Hardcover - Buy Softcover - Buy PDF - Buy from EU - Buy in India - Buy T-shirt - Donate - For Teachers - Homework - Projects - News - Acknowledgements - Other Books Welcome to Operating Systems: Three Easy Pieces (now version 1.00 -- see book news for details), a free online operating systems book!
The book is centered around three conceptual pieces that are fundamental to operating systems: virtualization, concurrency, and persistence. In understanding the conceptual, you will also learn the practical, including how an operating system does things like schedule the CPU, manage memory, and store files persistently. Lots of fun stuff! This book is and will always be free in PDF form, as seen below. For those of you wishing to BUY a copy, please consider the following: Can't bear to go out in public without an operating system?

About the Speaker: Conrad Kramer Conrad Kramer started developing for iOS after he got involved with the jailbreak scene back in 2010 with his first tweak Graviboard. Since then, he has gotten into regular iOS development and worked on various open source projects in the Cocoa community, like AFOAuth2Client and WFNotificationCenter.
Conrad now spends all of his waking hours on Workflow, an automation tool for iOS, where he works on anything from the server backend to building the complex drag and drop interactions. I’m Conrad Kramer, an iOS developer at Workflow, and I will discuss reverse engineering of iOS apps. There are two pain points when you’re doing reverse engineering. Operating tools are difficult because the tools themselves are usually not very well documented and pretty obscure. I decided to start with a test subject, Lyft’s iOS app, because it’s written entirely in Swift. Sitios Web donde aprender a programar gratis y algunos consejos para no perderte. Saber programar es cada vez más necesario en nuestros días. Muchos países ya incluyen la asignatura de programación en sus planes de estudio desde muy pequeños.
Los que ya estamos un poco más mayorcitos podemos aprender a programar por nuestra cuenta. Iniciarse no es difícil aunque requiere algo de tiempo y dedicación por nuestra parte para conocer los lenguajes más populares. El problema para los no iniciados es que frecuentemente la programación se percibe como un campo muy cambiante, donde hay una continua proliferación de versiones y pugnas entre casas comerciales que hacen que los lenguajes cambien muy rápidamente y al final resulta difícil tener claro qué es lo más conveniente aprender. Hoy existen en Internet muchas herramientas y páginas web gratuitas que te pueden ayudar a descifrar los secretos de ese código que ahora no entendemos. Me he tomado la libertad de recopilar lugares donde perderle el miedo a que nos muerda el código Code.org: Es un sitio pensado en niños. Depende.

Raymond As editor of the Jargon File and author of a few other well-known documents of similar nature, I often get email requests from enthusiastic network newbies asking (in effect) "how can I learn to be a wizardly hacker? ". Back in 1996 I noticed that there didn't seem to be any other FAQs or web documents that addressed this vital question, so I started this one.

Web scraping software enable webmasters, bloggers, journalist and virtual assistants to harvest data from a certain website whether text, numbers, contact details and images in a structured way which cannot be done easily through manually copying and pasting due to the large amount of data that needs to be scraped. Web Scraper Usage List of Best Web Scraping Software There are hundreds of Web Scrapers today available for both commercial and personal use. Import.io 1. 10 places where anyone can learn to code. Teens, tweens and kids are often referred to as “digital natives.” Having grown up with the Internet, smartphones and tablets, they’re often extraordinarily adept at interacting with digital technology.
But Mitch Resnick, who spoke at TEDxBeaconStreet, is skeptical of this descriptor. Sure, young people can text and chat and play games, he says, “but that doesn’t really make you fluent.” Mitch Resnick: Let's teach kids to code Fluency, Resnick proposes in this TED Talk, comes not through interacting with new technologies, but through creating them. The former is like reading, while the latter is like writing. He means this figuratively — that creating new technologies, like writing a book, requires creative expression — but also literally: to make new computer programs, you actually must write the code.
