Unlike the brain, most ANNs lack any kind of organization of units🧠 In our paper (ICLR 2025) with @mayukh091 @apurvaratan, we present TopoLoss, a simple, scalable way to add brain-like topography to AI models with minimal performance loss🧵 toponets.github.io

no wrestling with obscure AWS cli commands, no massive figshare zip files, zero pain fMRI dataset that takes <5 min to get running pip install mosaic-dataset

🧠Excited to share MOSAIC: a unified fMRI mega-dataset: 430k trials, 160k stimuli, 93 subjects (and more to come!) all in a single brain space Enables massive scale for modeling the visual cortex with just 2 lines of code github.com/murtylab/mosaic-d… 🐍pip install mosaic-dataset

Don't burn up your retina for science, mainakdeb.github.io/just-dar… no bs dark-mode for papers, PDFs, and most websites. free, no install/download required :)

What if different parts of a neural network were forced to learn different aspects of the input? They start showing specialized regions like the brain Listen to @MainakDeb19 talk about an architecture that got him an ICLR 2024 spotlight! New talk from @lossfunk!

My work got featured in @TEDAIVienna👀 AtMan (NeurIPS 2023) explains LLM outputs, telling you which part of the context was critical. ted.com/talks/jonas_andrulis… neurips.cc/virtual/2023/post…

Artificial neural networks can predict neural responses of the human brain (fMRI), however, they are vulnerable to small-scale adversarial attacks imperceptible to humans 🤖🧠 In our study with @nikolasmcneal @apurvaratan accepted at Neurips 2024 Unireps workshop, we find 👇

🚀At @NeurIPSConf tomorrow? Don't miss @nikolasmcneal and @MainakDeb19 's poster at the @unireps workshop on the adversarial sensitivity of vision encoding models of fMRI responses! A brief teaser about what they find.
