Feed: R-bloggers. Author: business-science.io - Articles. Last November, our data science team embarked on a journey to build the ultimate Data Science For Business (DS4B) learning platform. We saw a problem: A gap exists in organizations between the data science team and the business. To bridge this gap, we’ve created Business Science University, an online learning platform that teaches DS4B, using high-end machine learning algorithms, and organized in the fashion of an on-premise workshop but at a fraction of the price. I’m pleased to announce that, in 5 days, we will launch our first course, HR 201, as part of ... Read More

Feed: R-bloggers. Author: rOpenSci - open tools for open science. The Apache Tika parser is like the Babel fish in Douglas Adam’s book, “The Hitchhikers’ Guide to the Galaxy” . The Babel fish translates any natural language to any other. Although Tika does not yet translate natural language, it starts to tame the tower of babel of digital document formats. As the Babel fish allowed a person to understand Vogon poetry, Tika allows an analyst to extract text and objects from Microsoft Word. .----. ____ __\\\__ ___'--" .-. /___>------rtika '0' /____,--. ----B "".____ ___-" // / / ]/ Parsing files ...

Feed: R-bloggers. Author: Jonah. This post is by Jonah. Last week I posted here about the release of version 2.0.0 of the loo R package, but there have been a few other recent releases and updates worth mentioning. At the end of the post I also include some general thoughts on R package development with Stan and the growing number of Stan users who are releasing their own packages interfacing with rstan or one of our other packages. Interfaces rstanarm and brms: Version 2.17.4 of rstanarm and version 2.2.0 of brms were both released to provide compatibility with the new features in loo v2.0.0. Two of the ... Read More

Feed: Planet MySQL; Author: MySQL Server Dev Team; MySQL InnoDB Cluster has proven with the first GA release its potential as the native out-of-the-box HA solution for MySQL. With the second GA release, usability, stability and flexibility were greatly improved as described in the previous blog post. This tutorial aims to show how does a typical InnoDB cluster setup look like and how that setup even became simpler and more effective as before. It’s a great starting point for those not familiar with InnoDB cluster and shall help you to get started. For that purpose, we will use the new MySQL ... Read More

Feed: MariaDB Knowledge Base Article Feed. Author: . Additional Dependency Packages exist for 1.1.4, so make sure you install those based on the "Preparing for ColumnStore Installation" Guide. Note: Columnstore.xml modifications you manually made are not automatically carried forward on an upgrade. These modifications will need to be incorporated back into .XML once the upgrade has occurred. The previous configuration file will be saved as /usr/local/mariadb/columnstore/etc/Columnstore.xml.rpmsave. If you have specified a root database password (which is good practice), then you must configure a .my.cnf file with user credentials for the upgrade process to use. Create a .my.cnf file in the ...

Feed: R-bloggers. Author: R Views. I was surprised by greta. I had assumed that the tensorflow and reticulate packages would eventually enable R developers to look beyond deep learning applications and exploit the TensorFlow platform to create all manner of production-grade statistical applications. But I wasn’t thinking Bayesian. After all, Stan is probably everything a Bayesian modeler could want. Stan is a powerful, production-level probability distribution modeling engine with a slick R interface, deep documentation, and a dedicated development team. But greta lets users write TensorFlow-based Bayesian models directly in R! What could be more charming? greta removes the barrier ... Read More

Feed: R-bloggers. Author: Dr. Shirin Glander. Since I migrated my blog from Github Pages to blogdown and Netlify, I wanted to start migrating (most of) my old posts too – and use that opportunity to update them and make sure the code still works. Here I am updating my very first machine learning post from 27 Nov 2016: Can we predict flu deaths with Machine Learning and R?. Changes are marked as bold comments. The main changes I made are: using the tidyverse more consistently throughout the analysis focusing on comparing multiple imputations from the mice package, rather than comparing ... Read More
