Want embeddings for your neural recordings? You'll have better decoders with less data and a much more interesting story around connectivity. Check out @GeelingC and @czlwang's awesome work at #ICLR2025. From BrainBERT to the Population Transformer arxiv.org/abs/2406.03044
Geeling Chau@GeelingC

🎉Excited to share: My first ML conference paper, Population Transformer 🧠, is an Oral at #ICLR2025! This work has truly evolved since its first appearance as a workshop paper last year. So thankful to have worked with the best advisors + collaborators! 🤗 More soon!

Interested in large-scale neuroscience of language and multimodal representations? We have the dataset for you, the Brain Treebank! Come to our oral at NeurIPS. Today at 3:50pm PST, East Meeting room braintreebank.dev Now with extra foundation models arxiv.org/abs/2302.14367

With @IBM and @USAF_AI, next time someone tries to sell their object detector, measure how hard the dataset they're making claims on is. We've also learned there's something special about language-supervised vision models, check out the paper! objectnet.dev/mvt/ 3/3

Our new metric, Minimum Viewing Time, MVT, can be used to objectively judge dataset difficulty, to guide new dataset development, and even to speed up object detectors by using simple models for simple images. 2/3

What if we solved every object detection benchmark? Would machines be human-level? At @NeurIPSConf we measure how hard object detection datasets are for humans for the first time. Over 90% of benchmark images are easy! news.mit.edu/2023/image-rec… 1/3

@FinanceMuseum @smithsonian How is the @FinanceMuseum associated with the Smithsonian given its views on race and slavery? Does the Smithsonian support the view that the North stated the civil war as a form of economic aggression against the south?

Is this 1821 or 2021? @FinanceMuseum's "Genealogy of American Finance" doesn't mention slavery and redlining anywhere in 324 pages. They do take time to praise Wells Fargo for lending to "ethnic minorities". A bank that had to apologize for using slaves as collateral for loans...

You would this is from the Pocket Guide to Misogyny, but it's a popular book on negotiation. Reading the literature on negotiation strategies to teach machines how to bargain has been a shocking. How can business schools continue to teach this drivel in the 21st century?

@candacerossio That person said so many hateful and racist things. She kept saying "I'm a woman, we're stupid." Sadly I still see her around campus sometimes. The fact that someone like this can be part of our community, and that there is no recourse, is really outrageous.

"Wow- you don't cuss a lot or use ebonics. You're so different than the rest of them!" Approx 2 months into my PhD, about 50 feet from my office 🙃🙃 #BlackintheIvory
Shardé M. Davis, Ph.D.@DrShardeDavis

Wow! Y’all, @smileitsjoy & I started #BlackintheIvory less than 12hrs ago. I thought we’d be the only ones to use it, but it’s caught on. And so many folx are seeing our stories. We are TRUTH tellers. I KNOW it’s painful (trust). But if you feel comfortable, please cont. sharing.

Not only do word embeddings have biases, our work with @candacerossio shows adding vision to ground embeddings makes biases worse using new data & tests. Vision datasets are very biased arxiv.org/abs/2002.08911 Doesn't matter, it was in the 40% of #IJCAI rejections without review!

Our dataset, ObjectNet, a new kind of object recognition dataset that includes controls for biases, is being released at #NeurIPS this week. Removing biases leads to a sharp drop in performance, opening the way to more robust computer vision. objectnet.dev

@michaelhoffman @lpachter When a journal gets an ML paper, they should include ML reviewers. I can't imagine they had any in their normal pool. It would be nice if papers like this also included at least one ML coauthor that can vet what's going. There are so many of us! We aren't hard to find!

@MassRMV What's up with the wait times on the website? I'm in a line that's supposed to be 15 minutes long in Watertown. We're more than an hour out from seeing someone and 15 minutes in don't even have a ticket.

@AskLyft Just talked to them. Please don't drop this. He's going to end up hurting someone one day by losing it like that.

@lyft How do I report an abusive and obscene driver? He told me to fuck off because he didn't like where I'm going and sounded deranged and dangerous. I hope you can listen to his threatening call. Get this guy off your app!
