Eighth post of our series on classification from scratch. The latest one was on the SVM, and today, I want to get back on very old stuff, with here also a linear separation of the space, using Fisher’s linear discriminent analysis. Bayes (naive) classifier Consider the follwing naive classification ...

n this series of posts I will set out to recreate some of the visualizations from the book “Knowledge is Beautiful” by David McCandless in R.David McCandless is author of two bestselling infographics books and gave a TED talk about data visualization. I bought his second book “Knowledge is ...

In this post, we’ll return to the Kaggle data containing information on Pitchfork music reviews. In a previous post, I used this dataset to cluster music genres. In the current post, I will use R and the tidytext package (and philosophy) to examine the text of the music reviews. ...

A guest post by @MaxMaPichler, MSc student in the Group for Theoretical Ecology / UR Artificial neural networks, especially deep neural networks and (deep) convolutions neural networks, have become increasingly popular in recent years, dominating most machine learning competitions since the early 2010’s (for reviews about DNN and (D)CNNs see ...

A new update of my sjstats-package just arrived at CRAN. This blog post demontrates those functions of the sjstats-package that deal especially with Bayesian models. The update contains some new and some revised functions to compute summary statistics of Bayesian models, which are now described in more detail. hdi() rope() ...

Seventh post of our series on classification from scratch. The latest one was on the neural nets, and today, we will discuss SVM, support vector machines. A formal introduction Here takes values in . Our model will be Thus, the space is divided by a (linear) border The distance from point ...

If you’ve been on a New York City subway platform since January 2018, you should have noticed a countdown clock that displayed an estimate of when the next train would arrive. Although there’s no official record of when trains actually stopped at each station, the countdown clock data can ...

It’s happening – and this time in Swabia. eoda is bringing you the popular trainings for R to the South of Germany. Over more than 1500 satisfied participants have trained their practical data science skills with R trainings by eoda. Offering an Introduction to R and an Introduction to Data Mining ...

In an earlier post I focused on an in depth visit with CHAID (Chi-square automatic interaction detection). There are lots of tools that can help you predict an outcome, or classify, but CHAID is especially good at helping you explain to any audience how the model arrives at it’s ...

This week in AFL Nathan Fyfe one of the brownlow favourites got rubbed out for an ear tickler to Levi Greenwood When looking at the Brownlow odds, its a bit surprising to see Max Gawn listed as the second favourite. While he is having a great season, historically Ruckman have ...
