Exploration vs avoidance responses to negative stimuli is switched by maternal presence (precisely, maternal odor) for young rats. Interesting to know that "evolution deemed including that option crucial", as it's hardwired with a clear hormonal pathway www.nature.com/articles/nn1... web.archive.org

How do brain areas control each other? 🧠🎛️ ✨In our NeurIPS 2025 Spotlight paper, we introduce a data-driven framework to answer this question using deep learning, nonlinear control, and differential geometry.🧵⬇️

Me: "suggest how to rebuttal a reviewer that clearly used ChatGPT to generate reviews" Chatgpt: "you can quote to them the parts that are clearly generated by ChatGPT, explaining what the correct versions of the statements are [..]" yeah.. it's called "Human Feedback or Perish"

The Ponizsa illusion - Kanizsa triangle produces Ponzo illusion, but oddly it inverts apparent depth: the longer line looks closer! Also has an inversion effect like we studied in Altan et al 2025 Proc Roy Soc (doi.org/10.1098/rspb...) but it's also in reverse! 🤔 #visionscience #psychscisky

My university's computer science department just opened a Human-Centered Computing position.. it'd be awesome to have more colleagues working in human-centered deep learning, so please apply! dcc.ing.uc.cl/departamento...

I think this makes a lot of sense, although I'm still getting used to it

We are excited to share GPN-Star, a cost-effective, biologically grounded genomic language modeling framework that achieves state-of-the-art performance across a wide range of variant effect prediction tasks relevant to human genetics. www.biorxiv.org/content/10.1... (1/n)

2 tenure-track positions at UC Chile just opened.. in the maths/stats department. We have good growing links with the dept of computational engineering, so people wanting to fill the bridge maths-CS are welcome. Have a look (and maybe click "apply") here mathjobs.org/jobs/list/27...

Nice paper arxiv.org/abs/2506.01622

Last minute twist on these positions: they are available for EVERYONE, not just EU nationals 🎉 Closing date is tomorrow on some adverts (I won't be able to find and fix them) but we will consider late applications through to early next week (Monday 16th) #roots #rootecolology #biogeochemistry #phd

Fun fact: These C:N ratios are realistic values, but the mechanism is far more complex than "27=4+23" Maths: (a+b)/(c+d)=a/c + b/d is never true for a,b,c,d>0.. first hint to dig deeper Biology: main sink of C is respiration.. plant+hopper+frass/urea are NOT the only elements in the equation..

Nutrient Dilution and the Future of Herbivores: a short thread The fossil fuel folks claimed that all the extra CO2 is great for plants. Indeed, plant mass has increased globally by about 30% in the past century. But when you load a plant up the carbs, what happens to all its other nutrients?

Hot off the presses and so so thrilled. Thanks to @inaturalist.bsky.social + computer vision we found something beautifully simple: Red and orange flowers bloom later than all the other colors in the eastern United States. Paper here: authors.elsevier.com/a/1kwzh3QW8S...

It's fascinating that generating accurate references is so difficult for LLMs, no matter how much better they become. You can clearly specify the source, instruct the model to search, and even watch it retrieve the correct paper--yet it may still produce a fictitious citation.

Learned a cool word today: "tivrasamveg".. been doing lots of that recently

New preprint alert 🚨 How can you guide diffusion and flow-based generative models when data is scarce but you have domain knowledge? We introduce Minimum Excess Work, a physics-inspired method for efficiently integrating sparse constraints. Thread below 👇https://arxiv.org/abs/2505.13375

1/6 Why does the brain maintain such precise excitatory-inhibitory balance? Our new preprint explores a provocative idea: Small, targeted deviations from this balance may serve a purpose: to encode local error signals for learning. www.biorxiv.org/content/10.1... led by @jrbch.bsky.social

Been studying dungeon synth for the past few weeks. It's a quite diverse and creative genre. If I had more time on my hands, creating stuff like this would be definitely in my top 5 hobby list.. for now listening and trying to chant them back to a 7mo baby is enough www.youtube.com/watch?v=iwGE...

Super excited to share that the 𝗦𝗘𝗩𝗔 dataset and benchmark will be presented at #NeurIPS2023!✏️🧠🤖 🌐 Website - seva-benchmark.github.io 📜 Paper - arxiv.org/abs/2312.03035 💻 Code + Materials - github.com/cogtoolslab/... Thread below 🧵-

Question for #neuroscience people: On a population of neurons and I can do 2 possible stimulations with equal total intensity and duration: (1) periodic stimulation, same intensity for all pulses (2) random stimulation, random intensity The question: will (1) or (2) elicit more spikes in total?

today I'm heavily falling prey to the "I write much better reviews than the ones that I receive" fallacy

Wow, that's remarkable

I'm looking to gather material about the practical importance of the sign of curvatures in #informationgeometry .. what are the consequences in practical statistical estimation, if we know that the curvature in the regions of interest is positive/negative? Anyone knows about this?

This quote reminds me of one of the best talk titles, by a fluidodynamics colleague, Sergio Rica "Fluids: easy to drink, hard to understand" www.youtube.com/watch?v=jVVM...

I am surprised this is the first paper on this theme. Basically the idea is to have a two step procedure that estimates the Pareto set in multi-objective optimization, which in turn can be used for regularization (e.g. by its low dimensional structure). arxiv.org/abs/2503.08849

Looking for postdocs! if you are interested in Geometric Deep Learning, Computational Chemistry, TDA, Diffusion Models, then give it a thought :)

I find the bsky feed very noisy, so I asked Claude to help me make an algorithmic feed. It's dead simple: I take a small LLM from sentence_transformers, and I take the average embedding of what I tweet minus the average in my base feed. I compute the projection and apply a threshold

Gero Friesecke wrote an OT book! Chapter 2 is the main highlight compared to other texts: The finite marginal case to me is very illuminating for the general theory. Also it has an emphasis on the multimarginal case (Gero works on DFT where that's used). Sadly, the book is paywalled and not cheap

🤹 Excited to share Erwin: A Tree-based Hierarchical Transformer for Large-scale Physical Systems joint work with @wellingmax.bsky.social and @jwvdm.bsky.social preprint: arxiv.org/abs/2502.17019 code: github.com/maxxxzdn/erwin

Didn't know about this identifiability result (attaching assumption 1 from cited paper). As w2v linear algebra disentangling of analogies like king-man+woman=queen only works under independence assumptions conditioned on context, I'm curious to see how this work extends it beyond that hypothesis.

If you'd like to avoid the bends, the TL;DR is that RL lets us filter down our search space to only those policies that are optimal for relatively simple verifiers. Paper is at arxiv.org/abs/2503.01067. Joint w/ the all-star cast of Sanjiban Choudhury, Wen Sun, Steven Wu, and Drew Bagnell. [2/n]

This kind of grant is nice, you co-apply with a "mentor" and have to take 12 months leave to go learn/work with them, and it's open to non-US applicants. The idea seems to be to help entering a new field during a sabbatical year. Wondering if there are other similar ones around..

this is a very nice format: you apply together with a "mentor" and have to take a sabbatical of 12 months so that mentor guides you within a new field

wow very unusual fishesofaustralia.net.au/home/species...

arxiv.org/pdf/2501.12997 nice paper, comparing tree depth with chain of thought depth (it's wierd when you get to know work of colleagues from arxiv only, but that's life)

I read somewhere that few things make cowards happier than the humiliation of the brave. This is one of the most shameful and disgusting pressers I have seen.

I'm not a big fan of number theory, but I like patterns.. some parts of this video were pretty engaging www.youtube.com/watch?v=dgZb...

worth a visit

true. some finer classification (of this or other kind) would help also because with the high number of submissions it's time consuming to parse for a human

Main result looks like this.. the mentioned "procedure" is an abstract one, so the point is not applicability, right? I'm not familiar with the niche of research that this interests to

An enjoyable talk by Terence Tao. I was supposed to attend in person (thanks to Teresa Huang at Flatiron), but fell sick. :( youtu.be/5ZIIGLiQWNM?...

arxiv.org/abs/2502.12717 so "small combinations of generators are all you need".. but will this true at scale?
