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: Planet MySQL; Author: The Pythian Group; Introduction In this post we will explore one approach to MySQL high availability with HAProxy, Consul and Orchestrator.Let’s briefly go over each piece of the puzzle first:– HAProxy is usually installed on the application servers or an intermediate connection layer, and is in charge of connecting the application to the appropriate backend (reader or writer). The most common deployment I’ve seen is to have separate ports for writes (which are routed to the master) and reads (which are load balanced over a pool of slaves).– Orchestrator’s role is to monitor the topology and ...

Feed: Planet MySQL; Author: MySQL Server Dev Team; The MySQL Development Team is proud to announce the second GA release of InnoDB cluster! We listened carefully to the feedback we got from the previous major release (1.0 GA) and the last release candidate (8.0.4 RC) and incorporated many of the suggested changes. And that’s not all, we have introduced exciting new features and fixed several bugs to reach the desired maturity state. Here are the highlights of this release! MySQL Shell 8.0 For this release, we have, as always, focused on the usability of InnoDB cluster as a whole. With ... Read More

These are my sketchnotes for Sam Charrington’s podcast This Week in Machine Learning and AI about Reproducibility and the Philosophy of Data with Clare Gollnick: Sketchnotes from TWiMLAI talk #121: Reproducibility and the Philosophy of Data with Clare Gollnick You can listen to the podcast here. In this episode, i’m joined by Clare Gollnick, CTO of Terbium Labs, to discuss her thoughts on the “reproducibility crisis” currently haunting the scientific landscape. For a little background, a “Nature” survey in 2016 showed that more than 70% of researchers have tried and failed to reproduce another ... 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

Feed: R-bloggers. Author: Marcelo S. Perlin. – My paper about the penetration of predatory journals in Brazil, Is predatory publishing a real threat? Evidence from a large database study, just got published in Scientometrics!. The working paper version is available in SSRN. This is a nice example of a data-intensive scientific work cycle, from gathering data to reporting results. Everything was done in R, using web scrapping algorithms, parallel processing, tidyverse packages and more. This was a special project for me, given its implications in science making in Brazil. It took me nearly one year to produce and execute the ... Read More
