Happy to share the first article of my PhD, which is now available as a pre-proof!
We looked at methods used to adjust existing (AI/ML) clinical prediction models to new contexts, like different hospitals, clinical domains or to a specific individual.
Curious to hear your thoughts!😃

Plug-and-play use of tree-based methods: Consequences for clinical prediction modelling
Tree-based models such as Random Forest and XGBoost are increasingly being used for
clinical prediction, but certain aspects of their behavior are often overlooked. This
article aims to illustrate the...

New paper! 😃 We talk about using tree-based methods, such as Random Forests, for clinical prediction & what (not) to expect from them, with many illustrations. Let me know what you think!

Happy to share the first paper of my PhD is published☺️!
In case you like to use class imbalance corrections, maybe it is interesting. Let me know what you think!

This might be the first time after 10 years that boosted trees are not the best default choice when working with data in tables.
Instead a pre-trained neural network is, the new TabPFN, as we just published in Nature 🎉

Some time ago I wrote a non-technical introduction to marginal effects, in case you don't know the underlying logic yet. The idea is to use your model as a prediction machine that can be queried to return answers to precisely the questions you're interested in.

✨ Unleash your inner stats sparkle ✨ with this very non-technical introduction to marginal effects
Let’s admit right away that “marginal effects” doesn’t sound like the most sexy topic. I’m not saying that to further marginalize these poor effects. It’s just that statistics, in and of itself, barel...
