Feed: Featured Blog Posts - Data Science Central. Author: Nishtha Saxena. Data is growing every minute, and it’s not showing any sign of stopping. The pylon holding up the commercial enterprise of today is information – and it’s been the same way for decades. Petabytes and Exabytes of data racing through the information expressway of the 21st century, however have companies across the world scurrying to assimilate the most audacious datasets possible – all in the hope of gleaning that extra insight, that extra edge, over the others in the race. If you aren’t leveraging data, your own or from ... Read More

Feed: Planet big data. Author: Samantha Leggat. It feels like 1999 all over again, when Y2K was looming and IT pros were pulling consecutive all-nighters to get ready for it. GDPR, which is a set of rules under which the EU strengthens data protection for approximately 750 million people, is more than cleaning email lists and landing pages.

But let’s look away from the doom and gloom toward the light and opportunities. Yes, there are opportunities. Let’s look at ... Read More

Feed: Featured Blog Posts - Data Science Central. Author: Capri Granville. The Explainable Machine Learning Challenge is a collaboration between Google, FICO and academics at Berkeley, Oxford, Imperial, UC Irvine and MIT, to generate new research in the area of algorithmic explainability. Teams will be challenged to create machine learning models with both high accuracy and explainability; they will use a real-world financial dataset provided by FICO. Designers and end users of machine learning algorithms will both benefit from more interpretable and explainable algorithms. Machine learning model designers will benefit from Model explanations, written explanations describing the functioning of a ... Read More

Feed: R-bloggers. Author: Thinking inside the box. A maintenance update of RcppGSL just brought version 0.3.5 to CRAN, a mere twelve days after the RcppGSL 0.3.4. release. Just like yesterday’s upload of inline 0.3.15 it was prompted by a CRAN request to update the per-package manual page; see the inline post for details. The RcppGSL package provides an interface from R to the GNU GSL using the Rcpp package. No user-facing new code or features were added. The NEWS file entries follow below: Changes in version 0.3.5 (2018-05-19) Update package manual page using references to DESCRIPTION file [CRAN request]. Courtesy ... Read More

Feed: R-bloggers. Author: aghaynes. The openrouteservice provides a new method to get geodata into R. It has an API (or a set of them) and an R package has been written to communicate with said API(s) and is available from GitHub. I’ve just been playing around with the examples on this page, in the thought of using it for a project (more on that later if I get anywhere with it). Anyways…onto the code…which is primarily a modification from the examples page I mentioned earlier (see that page for more examples). devtools::install_github("GIScience/openrouteservice-r") Load some libraries library(openrouteservice) library(leaflet) Set the API ...
