Unserious post:

Now that (some) #AI researchers and engineers have rockstars-level salaries and notoriety, will they also have stage (or, better, paper) names?

Made it alive and well to the last day of #ACL2025NLP? Hats off you to you (well…us…)!!!

Time to collect the last energy and pass by our poster this afternoon 😀

Lorenzo Bertolini @lorenzoscottb.bsky.social · Jul 25

I’ll be at #ACL2025NLP next week, with a paper for the #GeBNLP workshop!

In this work, we tested the ability of a task-level explainability method to trace biological-sex biases in medical image classification, using general and biomedical VLMs.

Not pressing _this_ work at #ACL2025NLP, but always happy to chat NLP/AI for dream analysis 😴🤖

Lorenzo Bertolini @lorenzoscottb.bsky.social · Jul 23

👋 #sleeppeeps In this new work, we show how multiple LLMs appear to easily process #dreams, and reflect previously observed differences in reports (e.g., male-female, blind-sighted).

We also argue for caution linking dreams and bizarreness when using #LLMs

Introducing PreDA (prefix-based dream annotation), a set of generative LLMs tuned to annotate dream reports for 6 Hall & Van De Castle features! The paper will be presented at LOD 25 conference later this year as a long contribution. Models available here huggingface.co/jrc-ai

💤 As I approach the end of my PostDoc at IMT Lucca, I’m looking for a new job!

🧠 Ideally: Research roles related to sleep/dream/consciousness/cognitive science.

🤖 Open to scientific writing & data analysis, too.

📍 Milan, nearby areas, or Switzerland.

DMs open 💃🏼

Would computational approaches like open source toolkit and/or trained models (e.g. LLMs) be of interest too?

It's Sunday morning so taking a minute for a nerdy thread (on math, tokenizers and LLMs) of the work of our intern Garreth

By adding a few lines of code to the base Llama 3 tokenizer, he got a free boost in arithmetic performance 😮

Good question, but o don’t think so. I haven’t seen/found anyone yet.

Lorenzo Bertolini @lorenzoscottb.bsky.social · Nov 20

Thanks, but it seems that the response is quite full of errors/hallucinations. In the paper of the first two datasets, there is no mention of existing age-based metadata (nor in the dataset download web page), while the third I donìt think it qualifies as histopath.

Lorenzo Bertolini @lorenzoscottb.bsky.social · Nov 20

Hi alI quick dataset question:

I’m looking for a collection of histopathological images (no specific requirements wrt organ/disease/task) which includes metadata on participants’ (approximate) age.

Any suggestion?
