Dream x Engineering Symposium A gathering of world leaders in sleep and dream science exploring how we can influence dreaming with precision to improve well-being, accelerate learning, and treat clinical conditions.

👋 #sleeppeeps, this weekend I’ll be at the DxE simposyum at MIT to present some preliminary work at the intersection of AI and neuroscience to trace #dream event in event #EEG signal. Come say hi at the event, or drop a line if you’re in the Boston area and wanna chat 😀

All the models are back online, and the full paper should be out soon too 😃

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 😀

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

Strengths and Limitations of Word-Based Task Explainability in Vision Language Models: a Case Study on Biological Sex Biases in the Medical Domain Lorenzo Bertolini, Valentin Comte, Victoria Ruiz-Serra, Lia Orfei, Mario Ceresa. Proceedings of the 6th Workshop on Gender Bias in Natural Language Processing (GeBNLP). 2025.

Paper: aclanthology.org/2025.gebnlp-...

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.

Frontiers | Dreams are more “predictable” than you think IntroductionA growing body of work has used machine learning and AI tools to analyse dream reports, and compare them to other textual content. Since these to...

👋 #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

Happy to share that our work on #conformalprediction for pulmonary nodule detection has been accepted for presentation at COPA 25 conference!

💤 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 😮

E quindi come si sta da queste parti?

Work in progress -- suggestions for NLP-ers based in the EU/Europe & already on Bluesky very welcome!

Heya, happy to be on the list if there is still a slot 🙂

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

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.

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?

A useful and very informed add to the debate would also be @lampinen.bsky.social 🙂

YouTube video by Manlio De Domenico The “great Xodus” and the growth of BlueSky

As a computational social scientist I could not miss to follow this beautiful creature: the BlueSky social network during its growth in the last hours!

In this video I show just a snapshot for about 210k users and their 500k-ish connections #academicsky

Nice to see so many new #sleeppeeps on #SleepSky! I’m just gonna leave this here again 😅

(btw the paper and DReAMy abstract have now been published!)

Statistical Uncertainty in Word Embeddings: GloVe-V

Neural models, from word vectors through transformers, use point estimate representations. They can have large variances, which often loom large in CSS applications.
