1/2 Are LLMs doomed to hallucinate? No, says OpenAI's Adam Kalai at the Simons Institute workshop on The Role of TCS in Modern Machine Learning. "I don’t think it’s an inevitable problem. We can drastically reduce the amount of hallucinations." Video: simons.berkeley.edu/talks/adam-k....

1/2"Machine Learning is starting to look very different from what it looked like before": Tom Mitchell of @cmu.edu at the Simons Institute workshop on The Role of TCS in Modern Machine Learning. Video: simons.berkeley.edu/talks/tom-mi...

1/2 We've heard of the curse of dimensionality. But what about the curse of multilinguality? "If you try to pack more languages into the same size model, they are each going to degrade," said @shaynelongpre.bsky.social of @mit.edu at the Simons Institute.

1/5 Empirical conclusions depend on data and on human decisions made during the research process. @zstevenwu.bsky.social (@cmu.edu) spoke at the Simons Institute of using agents with unique personas to induce diversity in AI decision making, the baseline being the "Standard Persona."

1/4 Remember Sydney, the chatbot that urged a @nytimes.com columnist to break up with his wife? Or how an LLM fine-tuned to output insecure code became misaligned on tasks unrelated to coding? What do these have in common? — Roger Grosse of @anthropic.com and U of Toronto at the Simons Institute.

1/4 Matus Telgarsky of @newyorkuniversity.bsky.social's Courant Institute on Peter Bartlett’s unique contributions to theoretical ML through the 1990s: “For people like me, who came [into the field] in the 2000s, [his papers were] like a shining light.”

1/3 In 1958, the NY Times wrote about Frank Rosenblatt's perceptron, as an "embryo of computer designed to read and grow wiser." @ucsandiego.bsky.social's Misha Belkin examined this astonishing claim and came to a surprising conclusion, at a Simons Institute workshop honoring Peter Bartlett's work

1/4 Foundation Models: "We don't really know what we should expect [the phrase] to mean...and this causes real challenges," said Matthew McDermott of @columbiauniversity.bsky.social, at the Simons Institute workshop on Theory of Computing and Healthcare. We need a formal definition, he said.

From our friends at Berkeley Math. math.berkeley.edu/about/events...

1/2 Ken Rothman of @bostonu.bsky.social began his Distinguished Lecture at the Simons Institute on "Epidemiology is Easy – Anyone Can Do It" with a caveat: “Anyone can attempt to do it but doesn’t always work out that well.” He spoke at the workshop on Theory of Computing and Healthcare.

1/2 "There is sort of an obligation on the part of somebody who spends a lot of time thinking about privacy to open with the bad news," said Katrina Ligett of HUJI, talking about Research on Sensitive Data at the Simons Institute workshop on Theory of Computing and Healthcare.

Join us at 3:30 p.m. PT. Register to attend or access the livestream. simons.berkeley.edu/events/respo...

1/3 Will increasing compute and training data continue to improve performance of foundation models? Maybe. "I’m interested in asking: if it’s not the case, then why?" said Sewon Min of @ucberkeleyofficial.bsky.social at the Simons Institute workshop on Federated and Collaborative Learning Boot Camp

1/2 "The most striking finding we had is that the students that practiced math problems with ChatGPT without any guardrails did 17% worse on immediate subsequent exam where they did not have AI assistance." Hamsa Bastani of @upenn.edu at the Simons Institute. simons.berkeley.edu/talks/hamsa-...

1/2 Given two randomized control trials, RCT1 (100 participants) & RCT2 (1000), intuition says that RCT2 gives the better estimate of treatment effect.
