We are entering the fifth era of science. Mathematician @ninamiolane.bsky.social explains, "Instead of hoping AI will magically handle limited, noisy, specialized data, we need experts to tailor algorithms to the realities of fields like biology and medicine." Read the full article here:

🚀 Build fairer personalized ML! Our work introduces tools to evaluate trade-offs in accuracy, fairness & explanation quality. 📷Read “When ML Gets Personal” here: [http://arxiv.org/abs/2502.02786] @ninamiolane.bsky.social @gbg141.bsky.social

📊Experiments on real-world healthcare MIMIC-III data reveal: • Some subgroups benefit from personalization, others face worse predictions. • Prediction gains ≠ better explanations. • Fairness-aware ML practitioners need tools to assess when personalization helps vs. harms

Key Contributions ✅Framework to evaluate personalization across ML models ✅Finding:Fairness in accuracy≠fairness in explainability ✅New theoretical bounds on reliably evaluating personalization ✅Evidence:Regression models can handle more attributes than classification models

Personalization is everywhere, from healthcare to recommendations. While using user attributes (e.g. age, race) can boost accuracy, does it always? And at what cost to model explainability? (👇See table below for real gains or losses from personalizing a model with race and age).

🤩 Personalized ML is the engine of data-driven digital twins... ...but how does personalizing a model impact its accuracy and explainability, especially in low-data regimes?🧐 Find our paper w/ @louisacornelis.bsky.social @gbg141.bsky.social Haewon Jeong at #ICLR2026🇧🇷! @ucsbengineering.bsky.social

The tutorial "Flow With What You Know" was just awarded "Best Blog Post" for ICLR 2025! cf. iclr-blogposts.github.io/2025/about/

Been musing on the geometry of disentangled representations & factorization: Doing it by construction seems like a limiting inductive bias. What if you just add a soft geometric constraint to the loss and let the latent space sort itself out? Easy and tunable. 1/3

@abbybertics.bsky.social s reports from campus about an education system in crisis, and asks what the future might look like as students begin to tap into a tool that can think quicker, write faster and teach better than many of their instructors. 🎙️Listen here: www.economist.com/podcasts/202... !

As students tap into #AI tools that can teach better than their instructors, what does the future of education look like? 👉 @abbybertics.bsky.social from our lab @geometric-intel.bsky.social explores this question for the #TheEconomist !

Thus far, engineering has outpaced theory in the science of intelligence. But Tomaso Poggio is hopeful that theories can catch up. #neuroskyence www.thetransmitter.org/brain-inspir...

Thrilled to share @ninamiolane.bsky.social 's OpEd in @insidehighered.com with Annie K. Lamar! Open-source software and scientific infrastructure fuel discovery by removing barriers – not creating them. Time to start treating open science as the public good it is🔬💡

Thanks @insidehighered.com for publishing our OpEd w Annie K. Lamar #publicvoices of The Oped Project @ucsantabarbara.bsky.social ! 🤖Open source software & infra accelerates scientific discoveries by removing financial & technical barriers. It's about time we start treating it as a public good👇

This year I’ve been volunteering for The OpEd Project by helping writers from different backgrounds refine and place opinion pieces. They sent me a holiday gift! They didn’t need to. It’s been wonderful to work with these writers.

🔈 My first op-ed as a Public Voices Fellow on Technology in the Public Interest with The OpEd Project, out today, encourages health organizations to remember that AI is not the solution to every problem; instead, community priorities, not technology, should come first. 🔈

Thanks @thetransmitter.bsky.social for the feature! In our dementia work: 🧠 We predict cognitive decline by detecting early molecular signs. 🤖 We use LLM-augmented XAI to map key proteins to literature & accelerate biomarker discovery. @louisacornelis.bsky.social G Bernardez R Saloner K Casaletto

How are better tools and bigger datasets transforming the field? In a new special report, @thetransmitter.bsky.social explores the state of neuroscience and provides context on the field's focus, output, people and funding. Explore now: www.thetransmitter.org/state-of-neu...

Recently have been doing virtual reality experiments with mice in complex, open world environments. No linear tracks. No T-mazes. No simple gratings. No binary choices. No blocky, high contrast environments. Those are great for some experiments, but we want to focus on COMPLEX processing. (6/n)
