First up: Alexander Gibson @alexdgibson.bsky.social: Poor Data Provenance in Published Clinical Prediction Model Research.
I was seriously concerned about some of the Kaggle Datasets - those on stroke and diabetes raised concerns about data being fake.

Ok, time for a short thread about this paper.

My sense over the past six months or so is that chain-of-thought prompting as used in e.g. ChatGPT o.3 improves substantially upon previous systems such as ChatGPT 4.o, at least for certain tasks.

But how revolutionary is it?
If I have time I'll put together a more detailed thread tomorrow, but for now, I think this new paper about limitations of Chain-of-Thought models could be quite important. Worth a look if you're interested in these sorts of things.

Reading over my brother’s undergraduate assignment.

Criteria has a section: “Is there an appropriate amount of detail in this section so that you could replicate this study?”

I don’t remember learning about replication in my undergrad! Nice to see it getting some air time.
