Feed: Planet MySQL; Author: Dave Stokes; JSON has proven to be a very import data format with immense popularity. A good part of my time for the last two or so years has been dedicated to this area and I even wrote a book on the subject.  This is a comparison of the implementations of handling JSON data in MySQL and MariaDB. I had requests from the community and customers for this evaluation. JSON Data Types Are Not All Equal MySQL added a JSON data type in version 5.7 and it has proven to be very popular.  MariaDB has  JSON ... Read More

Feed: Microsoft Azure Blog. Author: Ricardo Mendes. More and more we hear from our customers that building hybrid applications is necessary for their business. While Microsoft Azure continues to be the platform of choice for building applications, Azure Stack and Azure together enable building hybrid applications. The consistent experience across both makes it easy. You can use Azure services from anywhere, whether at the bottom of a mine, from inside a container on a cargo ship in the middle of the Pacific Ocean, or from the top of Aconcagua, the tallest mountain in the Andes. Literally, you can run apps ... Read More

Feed: R-bloggers. Author: ntguardian. Introduction Over the past few weeks I’ve published articles about my new package, MCHT, starting with an introduction, a further technical discussion, demonstrating maximized Monte Carlo (MMC) hypothesis testing, bootstrap hypothesis testing, and last week I showed how to handle multi-sample and multivariate data. This is the final article where I explain the capabilities of the package. I show how MCHT can handle time series data. I should mention that I’m not focused on the merits of the procedures I use as examples in these posts, and that’s going to be the case here. It’s possible ... Read More

Feed: R-bloggers. Author: John Mount. This note is about attempting to remove the bias brought in by using sample standard deviation estimates to estimate an unknown true standard deviation of a population. We establish there is a bias, concentrate on why it is not important to remove it for reasonable sized samples, and (despite that) give a very complete bias management solution. Everitt’s The Cambridge Dictionary of Statistics 2nd Edition, Cambridge University Press defines a “statistic” as: A numeric characteristic of a sample. Informally we can say a statistic is a summary. And this lets us say the field of ... Read More

Feed: AWS Compute Blog. Author: tiffany jernigan (@tiffanyfayj). Post by Vikrama Adethyaa, Solution Architect and Tiffany Jernigan, Developer Advocate Containers are an increasingly important way for you to package and deploy your applications. They are lightweight and provide a consistent, portable software environment for applications to easily run and scale anywhere. A container is launched from a container image, an executable package that includes everything needed to run an application: the application code, configuration files, runtime (for example, Java, Python, etc.), libraries, and environment variables. A container image is built up from a series of layers. For a Docker image, each ... Read More

Feed: Featured Blog Posts - Data Science Central. Author: Muhammad Rizwan. After detecting a face in an image, as seen in the earlier post ‘Face Detection Application’, we will perform face landmark estimation. Face landmark estimation means identifying key points on a face, such as the tip of the nose and the center of the eye. There are different estimation models based on the number of face landmark points. The 5 points model is the simplest one which only detects the edges of each eye and the bottom of the nose. 5 points face landmark model Other models include 68 points ... Read More

Link to webscraping the data Link to Analysis, part 1 Introduction This is the third blog post that deals with data from the game NetHack, and oh boy, did a lot ofthings happen since the last blog post! Here’s a short timeline of the events: I scraped data from alt.org/nethack and made a package with the data available on Github(that package was too big for CRAN) Then, I analyzed the data, focusing on what monsters kill the players the most, and also whereplayers die the most @GridSageGames, developer of the roguelike Cogmind and ...

Feed: Planet big data. Author: David Smith. T-Mobile, the global telecommunication company, is using R in production to automatically classify text messages to customer service  and route them to an agent that can help. The AI@T-mobile team used the keras library in R to build a natural language processing engine with Tensorflow, and deployed it to production as a docker container. The MRAN Time Machine ensures the container gets fixed R package versions for reproducibility.  While you may think first of Python for building production AI models, the keras library in R has already proven to be a first-class interface for building ...
