Interpretable "AI" is just a distraction from safe and useful "AI"

No.

I wonder who those people are who come here dying to know what GenAI has done with some prompt you put in

If you think AI is cool, wait until you learn about regression analysis

NEW PREPRINT Explainable AI refers to an extremely popular group of approaches that aim to open "black box" AI models. But what can we see when we open the black AI box? We use Galit Shmueli's framework (to describe, predict or explain) to evaluate arxiv.org/abs/2508.05753

The healthcare literature is filled with "risk factors". This word combination makes research findings sound important by implying causality, while avoiding direct claims of having identified causal associations that are easily critiqued.

When forced to make a choice, my choice will be logistic regression model over linear probability model 103% of the time

Post just up: Is multiple imputation making up information? tldr: no. Includes a cheeky simulation study to demonstrate the point. open.substack.com/pub/tpmorris...

You can have all the omni-omics data in the world and the bestest algorithms, but eventually a predicted probability is produced & it should be evaluated using well-established methods, and correctly implemented in the context of medical decision making. statsepi.substack.com/i/140315566/...

Depending which methods guru you ask every analytical task is “essentially” a missing data problem, a causal inference problem, a Bayesian problem, a regression problem or a machine learning problem

Surprisingly common thing: comparisons of prediction models developed using, say, Logistic Regression, Random Forest and XGBoost with conclusion XGBoost is "good" because it yields slightly higher AUC than LR or RF using the same data Fact that "better" doesn't always mean "good" seems lost

What is common knowledge in your field, but shocks outsiders? Validated does not mean it works as intended. It means someone has evaluated it (and may have concluded it doesn’t work at all)

**New Lancet DH paper** "Importance of sample size on the quality & utility of AI-based prediction models for healthcare" - for broad audience - explains why inadequate SS harms #AI model training, evaluation & performance - pushback to claims SS irrelevant to AI research 👇 tinyurl.com/yrje52fn

People always ask me, “how do I know my manuscript is done?” There’s only one way, my friends. If your file name looks something like this: Manuscript - Final Draft 3.7 FINAL FINAL - FINAL (5).docx Then, and only then, is it time.

Re-proposing the Occam's taser: an automatic electric shock for anyone riding the AI hype train making their models unnecessarily complex

Rule of thumb: If your model requires data to look like this (balanced after SMOTE), then maybe you want to use a different model

We should really ban all use of AI from all our education because the use of AI will make our students dumb, and banning innovation has worked really well before

As scientists it is difficult to stay in love with the questions once you fall in love with the answers

So glad they let us use this turn-of-phrase @maartenvsmeden.bsky.social doi.org/10.1016/j.jc...

So.... about using large language models (e.g. chatGPT) for writing motivation letters for a job I get it! And honestly, use all the technology you need to write the best letter you can But after reading dozens of letters with almost EXACTLY the same intro paragraph I do get a bit tired of it

Only 5 days left to apply for our 3 PhD positions at the @umcutrecht.bsky.social 🎓 🏃🏃‍♀️

Code or it did not happen

‘Wow, this treatment was no better than placebo – because the placebo was so effective!’ It’s such a shame the term ‘placebo effect’ is so widely known and used. There are fundamental challenges with identifying it and most of the claims don’t even try. It’s just change-from-baseline every time.

Before citing a paper the least you can do is thoroughly read… 1st year student: the entire literature on the subject Grad student: the paper you cite Post-grad: title and abstract and scan the rest of the paper Professor: the title. PLEASE read the title

Industry that promises "explainability" to patients of their AI or other complex analytical models should be held against the highest standards which they will not be able to meet

The end of an era, but a new one begins. 🚀 Best of luck, Shan and Elena, in your future endeavors! And as for me… I'm looking for a new PhD candidate interested in methods research! I'm looking for a new PhD candidate interested in methods research! www.academictransfer.com/en/jobs/3503...

Five years ago @laurewynants.bsky.social and I started this living review. Within 1 year we reviewed >700 prediction models for COVID and we found many to be poor and decided to stop reviewing. Many external validation studies followed confirming many indeed were poor www.bmj.com/content/369/...

Nice summary of our recent paper on SMOTE w/ @alcarriero.bsky.social @benvancalster.bsky.social

ChatGPT is great but all I really want is MS powerpoint files that are < 10 MB

For everyone thinking that we simply tell doctors they should *not* use LLMs for decision making and that they will listen to that, just look at these numbers: "76% of respondents reported using general-purpose LLMs in clinical decision-making" www.fiercehealthcare.com/special-repo...

The best thing about being an AI bro is that you get to play in everybody’s junk yard

You all talk AI meanwhile I am still stuck in this world where MS Word refuses to do simple alignment and font tasks

This is sad...
