Interesting in how animals learn a sensory decision-making task from scratch? Come check out Helena Liu's (@helenaliu24.bsky.social) poster in the Saturday poster session at #cosyne2026 !

Proud to be a collaborator on this paper on compact deep neural network models of V4, with Ben Cowley (@benjocowley.bsky.social), Pati Stan, & Matt Smith, now finally out in print (by which I mean online).

Excited to be co-organising a #cosyne2026 workshop with Alison Comrie on 'algorithms for learning from scratch'! With a great line-up of speakers, we'll be tackling the question of what processes enable naive biological & artificial agents to adapt to new situations. Info here: tinyurl.com/4u8enf7k

New paper with @deanpospisil.bsky.social , in which we introduce a new estimator for the "signal eigenspectrum" (i.e., the eigenvalues of the noiseless population responses). We re-analyze data from Stringer et al 2019 and show eigenvalues of mouse V1 are well explained by a broken power.

Bichan Wu (@bichanw.bsky.social) & I wrote a tutorial paper on Reduced Rank Regression (RRR) — the statistical method underlying "communication subspaces" from Semedo et al 2019 — aimed at neuroscientists. arxiv.org/abs/2512.12467

Great opportunity to learn to use fancy neural data analysis tools developed at the @flatironinstitute.org. Sign up for this workshop at SFN 2025!

Now out in @natcomms.nature.com‬: Mice and monkeys spontaneously shift through comparable cognitive states - and it's written all over their faces! (1/7) www.nature.com/articles/s41...

Diffusion modeling folks: many sources (including Wikipedia) cite Robbins 1956 as the original source for Tweedie's formula (E[z | x] = x + sig^2 \grad log p(x)). But as far as I can tell — the formula appears nowhere in that paper. Did I miss it? Can anyone explain what's going on here?

"to run a contest that you end up not funding as a private organization at this time is… both extremely wasteful of these people’s time, and just devastating in terms of morale." I spoke with @aniloza.bsky.social at STAT today about HHMI's decision not to fund this round of Hanna Gray applicants.

We are writing a tutorial paper on reduced rank regression (RRR), aimed primarily at neuroscientists. Q: Does anyone have suggestions for where to publish such a paper?

"We are passionate about science and its benefits to society, but we fear more what will happen if we do not help defend everyone’s fundamental rights." Op-ed I co-wrote w/ @samwang.bsky.social @jpillowtime.bsky.social @ilanawitten.bsky.social & David Tank www.dailyprincetonian.com/article/2025...

This drone situation in NJ is bonkers! Patch has had the best coverage so far. patch.com/new-jersey/p...

(recycled form X @ 2021) Are you interested in the dimensionality of neural data, but missed our #BernsteinConference workshop? Worry not! Instead, join me in this long thread (1/37) attempting to summarise it and (my view of) the field more broadly.

Princeton folks — check out this story from Carolyn Jones about safety on our local roads! Interesting stats even if you're not a safety geek... 🧐

V. proud of this paper on "cell type dynamical systems", to appear at NeurIPS 2024 — led by the fearless @aditijh.bsky.social !!

If you've used @intlbrainlab.bsky.social data or tools in some way, could you spare 1 minute to tell us how? short survey: docs.google.com/forms/d/e/1F... Thanks in advance! 🙏
