Gradient-Boosting and Boostrap aggregating anything (alert: high performance): Part5, easier install and Rust backend

I stumbled upon Gaussian Processes when looking into how the MIPRO prompt optimisation algorithm works and felt compelled to learn more about it. It’s a very nifty application of Bayesian modelling to analyse functions where data points are hard...

This week we had a wonderful community call, From Novice to Contributor: Making and Supporting First-Time Contributions to FOSS, where Sunny Tseng, Pascal Burkhard, and Yaoxiang Li shared with us their experiences with, and advice for, first time cont...

The variance-covariance and the correlation matrices are two entities that describe the association between the columns of a two-way data matrix. They are very much used, e.g., in agriculture, biology and ecology and they can be easily calculated wi...

The fourth instalment of Shiny in Production is back this October, hosted at the Catalyst in Newcastle upon Tyne, with the super early bird deadline on the 31st of January! Set in the heart of Newcastle, this conference dives into the world of {s...

I sometimes use this fun interview question for aspiring data scientists: How are p-values distributed assuming the null hypothesis is true? I’ve heard a lot of reasonable answers, including: All very reasonable and intuitive answers which I would probably, at some point, have given myself. They’re also all ...

My final exam for the Monte Carlo course I taught last semester proved too much of a challenge for my fourth year students, despite being rather elementary and centred on accept-reject algorithms and importance/bridge sampling. One of the problems was a decomposition of the truncated Normal simulation method proposed ...

How can we teach “R for cell biologists” rather than teaching R to cell biologists? I’ve noticed that many R training courses will teach R – regardless of who is taking the course – and leave it to the participants to figure out how they can use R in their own ...
