Hey BlueSky! As a little weekend project, I have turned some of my #DataSci lecture notes into a blog post, now available on Towards Data Science 🥳 It's a little narrative primer on basic properties & common misconceptions on R-squared as evaluation metric for regression. Check it out!

Deeply disturbed and saddened by news of the death of Alexei Navalny.
Putin fears nothing more than dissent from his own people.

taught a fun first DataSci lecture for MSc students this week, and it turns out that debunking "myths" on properties (e.g., bounds) and meaning (e.g., % variance explained?!?) of R-squared is a great lead-up for a stats-to-prediction mindset shift. Hope to have time for a long-form post later on!

How predictable is neuroscience? Can LLMs outperform humans? Please participate in the BrainGPT.org survey to help us find out. You choose between two versions of a neuro abstract: the original vs. one with altered results. Which is which? research.sc/participant/... 1/2

While FOMOing over #EMNLP and prepping last lecture of the term (efficient LLM training/fine-tuning), I made a quick viz to explain model distillation. Up for grabs if you ever get frustrated over the lack of good figures to explain this.

New paper! We benchmarked lots of text & speech models on lang-based inference of neuropsych conditions, found that, while binary classification performance is stellar, multiclass is generally low, and discussed why this may be so. Spoiler: it's not the models, but perhaps diagnoses as a constructs👇
Can we predict depression & schizophrenia from speech? Many studies say yes! Work w @rockberta.bsky.social in Nature Mental Health shows that such markers do not discriminate between conditions & are rather markers of specific symptoms, often common across conditions. #neuroskyence #psychscisky 🧵 1/

grad students in need of a whole-brain fNIRS datasets (2+ tasks) to benchmark a CNN classifier they've developed. I have suggested openfnirs.org/data/ and tufts-hci-lab.github.io/code_and_dat.... Is there any other obvious resource I am missing and/or anyone owning such data and willing to share?
