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

Feed: R-bloggers. Author: S. Walsh. Ireland is a typically stable region from a seismic activity perspective as it is distant from major plate boundaries where subduction and sea-floor spreading occur. However, in reading the following article, I was surprised to discover that earthquakes occur quite frequently both off the Irish coast and within the country itself. Most of these events occur as a result of tension and pressure release in the crustal rock. The Irish National Seismic Network (INSN) maintains a dataset on 144 local earthquakes dating back to February 1980. The variables in the dataset are event date, event ... Read More

Feed: R-bloggers. Author: Chuck Powell. As I continue to learn and grow in using R I have been trying to developthe habit of being more formal in documenting and maintaining thevarious functions and pieces of code I write. It’s not that I think theyare major inventions but they are useful and I like having them storedin one place that I can keep track of. So I started building them as apackage and even publishing them to CRAN. For any of you who might findthem of interest as well. Overview A package that includes functions that I find useful for teachingstatistics ... Read More

Feed: R-bloggers. Author: Gavin L. Simpson. Regular readers will know that I have a somewhat unhealthy relationship with GAMs and the mgcv package. I use these models all the time in my research but recently we’ve been hitting the limits of the range of models that mgcv can fit. So I’ve been looking into alternative ways to fit the GAMs I want to fit but which can handle the kinds of data or distributions that have been cropping up in our work. The brms package (Bürkner, 2017) is an excellent resource for modellers, providing a high-level R front end to ... Read More

Read through to find valuable tips they shared and up your SAS game. My second interview at SAS Global Forum 2018 was with a SAS user who shared how SAS thinks a lot like an analytical person. What an interesting thought and one that I am sure will touch many chords among SAS users.

Feed: R-bloggers. Author: Mango Solutions. (Or, how to write a Shiny app.R file that only contains a single line of code) Mark Sellors, Head of Data Engineering This post is long overdue. The information contained herein has been built up over years of deploying and hosting Shiny apps, particularly in production environments, and mainly where those Shiny apps are very large and contain a lot of code. Last year, during some of my conference talks, I told the story of Mango’s early adoption of Shiny and how it wasn’t always an easy path to production for us. In this post ... Read More

Feed: Planet MySQL; Author: Valeriy Kravchuk; I stopped reviewing MySQL Release Notes for quite a some time, but major GA releases of MySQL do not happen often, so I decided to make an exception and write about some bugs from Community users fixed in MySQL 8.0.11 GA.I'll start with good news about MySQL 8.0.11 GA! You can get sources at GitHub, and I had no problems to build on Fedora 27 on my good old QuadCore box, using the following cmake command line: [openxs@fc23 mysql-server]$ cmake . -DCMAKE_BUILD_TYPE=RelWithDebInfo -DBUILD_CONFIG=mysql_release -DFEATURE_SET=community -DWITH_EMBEDDED_SERVER=OFF -DDOWNLOAD_BOOST=1 -DWITH_BOOST=/home/openxs/boost -DENABLE_DOWNLOADS=1 -DWITH_UNIT_TESTS=OFF -DCMAKE_INSTALL_PREFIX=/home/openxs/dbs/8.0...[openxs@fc23 mysql-server]$ time make -j ...
