The terms CI/CD stands for Continuous Integration and Continuous Delivery – Deployment. Before we jump into how all these work, let’s take a step back and walk through the process of ML. Most of the data scientists do their data analytics on their laptops. For every data analytics projects ...

Many organizations today are adopting data science practices as part of their digital transformation initiatives. However, most of them won’t reap the rewards of mining their data without a data strategy and a clear-cut blueprint for scaling data s...

A few weeks ago we released our new framework and, together with our customers, we have already implemented exciting use cases. YUNA elements is a lean, easy to learn, secure and scalable framework for the development, organization and administration of script-based data processing and analysis projects for the languages R, ...

This post was inspired by one of Thomas Neitmann’s posts showing how to write some debugging code in R and Python to automatically search code errors on StackOverflow. Below is a simpler example where we do this with Amazon’s site. In this blog we are going to write ...

I recently created a few datasets to facilitate analyzing the interaction between demographics and political party affiliations of US Congressional Districts. My goal was to create this graph: I added this data to Choroplethr and pushed the new version to CRAN. This post walks you through using these datasets, the ...

Did you know that Ohio’s state song is Hang On Sloopy, best known as a hit for the McCoys in 1965? Me either, but this week in the State-Off Tournament we’ll see if seventh seed Ohio (7) can cough hang on against second seeded Texas (2). We’ll also continue building ...

This fall, the R Consortium’s support for advancing data science in medicine continues with the third of three exceptional events, pulling together experts in their fields, including the Covid-19 Data Forum,... The post We’ll be at R/Pharma – Oct 12-15, 2020 appeared first on R Consortium.

theme_web_bw theme_web_classic theme_web_void This will be a very short post compared to the detailed stuff I usually write. Just what it says on the tin – I made some tweaks to my three favorite {ggplot2} themes – theme_bw(), theme_classic(), and theme_void() – to make ...

Spinning on that dizzy edge (Just Like Heaven, The Cure) This post talks about a generative system called Physarum model, which simulates the evolution of a colony of extremely simple organisms that, under certain environmental conditions, result into complex behaviors. Apart from the scientific interest of the topic, this model ...

Lately I’ve been publishing screencasts demonstrating how to use the tidymodels framework, from first steps in modeling to how to evaluate complex models. Today’s screencast admittedly does not result in the best performing model you’ll ever see, but it is really fun and uses this week’s #...

Co-varying predictors can be a messy business. They make estimates unstable, reducing our statistical power and making interpretation more difficult. In this post I will demonstrate how ignoring the presence of co-variation between predictors when exploring our models can lead to odd results and how we might deal with this ...

2020 has been a tough year, and I've been doing my best to keep busy (and distracted from all the insanity - both at the personal and worldwide levels). Earlier this year, I took a course in machine learning techniques and have been working on applying...
