We show face patches implement the following code through recurrent dynamics:
Detect face
If (face found)
Discriminate face
else
Continue to detect face
IMHO, our paper conclusively resolves a debate that has raged since I was a graduate student, about whether face patches are specialized for processing faces or not. It turns out domain-general folks were right early on, domain-specific folks were right later in the response.
So proud of @Yuelin_Shi and the entire team!
We’re hiring a new Lab Manager!
I’ve loved working in this lab — super supportive environment and meaningful work in AI + cognitive neuroscience
Highly recommend for anyone looking to gain research experience before grad school!

Honored that a piece I wrote made it to NYTimes. It's about how my mom's stroke changed my relationship to time, science, and nature. What a privilege to honor my mom in Modern Love.

🧩 Why do task vectors exist in pretrained LLMs?
Our new research uncovers how transformers form internal abstractions and the mechanisms behind in-context learning(ICL).
🚀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.

1/6 I usually don’t comment on these things, but @RylanSchaeffer et al.'s paper contains enough misconceptions that I thought it might be useful to address them. In short, effective dimensionality is not the whole story for model-brain linear regression, for several reasons: 🧵👇
(1) The spectral theory due to @canatar_a@jenellefeather@s_y_chung is misrepresented in this paper, and crucially relies on model alignment with brain data (this is already evident from their equations). In fact, they conclude that effective dimensionality alone doesn’t fully predict neural data.
(2) Even in this paper’s own Figure 2 (top left panel), networks with low participation ratios, like SRNN, still achieve high neural predictivity, already indicating that participation ratio is not a unilateral predictor of whether a model will match the brain via linear regression.
(3) Beyond MEC, this lack of a trend with effective dim. is also the case when looking at models in their match to macaque IT or human OTC. For example, Colin Conwell @_jacobprince_@talia_konkle et al.’s very thorough work: https://t.co/iWSiHOrUcd shows that effective dim isn’t related to linear prediction of human OTC (cf. their Figure 5). Moreover, in macaque IT, as @apurvaratan & others have seen, if you include very predictive models of IT responses, the effective dim to linear predictivity trend also doesn’t hold. (@jenellefeather & others don’t see this trend holding up in matches to auditory cortex either.)
(4) Furthermore, the models they cite participation ratios for, were also compared against several non-fitted metrics (like RSA, score distributions, simpler-than-linear mappings, etc.), which found similar conclusions that matched linear regression results, across MEC, IT, and auditory cortex.

This talk is quite accessible for computer scientists interested in cognitive and neuro questions. Also touches on many of the shared themes of the two areas.
