Bigger isn’t better, but major AI policies (like the Biden EO) focus only on model size & compute. However, models are useless without data! In our latest work, we highlight the need for data-centric AI policy and reveal the shortcomings of the status quo.

I'm a PhD student in the Electrical Engineering and Computer Science school (BAIR lab) at UC Berkeley. Including the summer stipend, we get paid approximately $47,700/year. They also cover health insurance and any fees. Additionally, first years in BAIR get a $5k grant.
To increase transparency around grad school stipends, retweet this tweet with your department, university, and annual stipend. I'll go first: I'm a PhD student in the Computing and Mathematical Sciences (CMS) department at Caltech, and I'm paid $36k/year.

I wholly disagree with this take. Show me something like SAM working on cluttered port scenes with layover and multi-pathing and then let's talk. Until then, keep working on SAR. And if anyone has better labeled then ship detection, then release them
To all the grad students working on yet another SAR ship detection model - I just saw someone in Slack use Meta’s new “Segment Anything” model on a port and it found all the ships, plus segmented the water from land.
Stop now. I repeat, stop now. It’s time to reevaluate.
