So excited for CCN2026!!! 🧠🤔🤖🗽
arguably the most important component of AI for neuroscience:
data, and its usability
Join us at #NeurIPS2025 for our Data on the Brain & Mind workshop! We aim to connect machine learning researchers and neuroscientists/cognitive scientists, with a focus on emerging datasets.

New preprint!
tl;dr — We ran around late at night to record wild rats in NYC and figured out how to quantify their behavior and environment. 🧵

In many brain areas, neuronal tuning is heterogeneous. But how does this diversity help behavior? We show how tuning diversity shapes representational geometry and boosts coding efficiency for perception in our new preprint: www.biorxiv.org/content/10.1...
(w/ @sueyeonchung.bsky.social&Tony Movshon)
Topics include but are not limited to:
•Optimal and adaptive stimulus selection for fitting, developing, testing or validating models
•Stimulus ensembles for model comparison
•Methods to generate stimuli with “naturalistic” properties
•Experimental paradigms and results using model-optimized stimuli
Consider submitting your recent work on stimulus synthesis and selection to our special issue at JOV!
What is the probability of an image? What do the highest and lowest probability images look like? Do natural images lie on a low-dimensional manifold?
In a new preprint with Zahra Kadkhodaie and @eerosim.bsky.social, we develop a novel energy-based model in order to answer these questions: 🧵
Just a few months until Cognitive Computational Neuroscience comes to Amsterdam! Check out our now-complete schedule for #CCN2025, with descriptions of each of the Generative Adversarial Collaborations (GACs), Keynotes-and-Tutorials (K&Ts), Community Events, Keynote Speakers, and social activities!
I’m happy to be at #VSS2025 and share what our lab has been up to this year!
I’m also honored to receive this year’s young investigator award and will give a short talk at the awards ceremony Monday
The symposium also serves to kick off a special issue of JOV!
"Choose your stimuli wisely: Advances in stimulus synthesis and selection"

Paper Deadline: Dec 12th
For those not able to attend tomorrow, I will strive to post some of the highlights here 👀 👀 👀
Super excited for our #VSS2025 symposium tomorrow, "Model-optimized stimuli: more than just pretty pictures".
Join us to talk about designing and using synthetic stimuli for testing properties of visual perception!
May 16th @ 1-3PM in Talk Room #2

This is joint work with fantastic co-authors from @flatironinstitute.org Center for Computational Neuroscience: @lipshutz.bsky.social (co-first) @sarah-harvey.bsky.social @itsneuronal.bsky.social @eerosim.bsky.social
These examples demonstrate how our framework can be used to probe for informative differences in local sensitivities between complex models, and suggest how it could be used to compare model representations with human perception.
In a second example, we apply our method to a set of deep neural network models and reveal differences in the local geometry that arise due to architecture and training types, illustrating the method's potential for revealing interpretable differences between computational models.
As an example, we use this framework to compare a set of simple models of the early visual system, identifying a novel set of image distortions that allow immediate comparison of the models by visual inspection.
This provides an efficient method to generate stimulus distortions that discriminate image representations. These distortions can be used to test which model is closest to human perception.
We then extend this work to show that the metric may be used to optimally differentiate a set of *many* models, by finding a pair of “principal distortions” that maximize the variance of the models under this metric.
We use the FIM to define a metric on the local geometry of an image representation near a base image. This metric can be related to previous work investigating the sensitivities of one or two models.
We propose a framework for comparing a set of image representations in terms of their local geometries. We quantify the local geometry of a representation using the Fisher information matrix (FIM), a standard statistical tool for characterizing the sensitivity to local stimulus distortions.
Recent work suggests that many models are converging to representations that are similar to each other and (maybe) to human perception. However, similarity often focuses on stimuli that are far apart in stimulus space. Even if global geometry is similar, the local geometry can be quite different.
We are presenting our work “Discriminating image representations with principal distortions” at #ICLR2025 today (4/24) at 3pm! If you are interested in comparing model representations with other models or human perception, stop by poster #63. Highlights in 🧵
