@tomgoldsteincs Saw this paper yesterday: https://t.co/4h3Bkb9Psg Performance is nowhere near current large models, but could have interesting implication with the mathematically interpretable framing. Would be curious what you think?

[Amy B. Zhang @Amy_B_Zhang]

@infoxiao Too true that was our standup today (Though in this case it’s trading effort for traceability)

@hokei hope you and those around you are ok! Very disturbed by the subway news… (somehow the phone number I have for you doesn’t seem to be correct)

In 2020, Renee DiResta (@noUpside) and the Stanford Internet Observatory worked to detect and track misleading election-related narratives. At the next DLI seminar, she describes the project's findings and how to apply them to health misinformation. More: https://t.co/XKvDYCnb5I

My TED talk launched! Wrote it 9 months ago then lost the iconic stage+audience due to COVID, but I still poured my❤️into it. Thanks to all who’ve encouraged me to keep speaking out over the past 5 years. I won’t stop fighting; our democracy’s at stake. https://t.co/Xkp2SwGT18

Our work on low-rank MDP approximation is on arXiv. We take a CLT-style view, reducing to a small number of states while still mimicking the first and second moments of the transition matrix. And this simple aggregation algorithm is backed theoretically. Excited to explore more!

There is such amazing solidarity! Laughing through tears at the lovely people sharing their voices and legends...

Very surprised to learn about #LightPolution from a ted talk given by astrophysicist Kelsey Johnson. It not only affects ecosystems but also damages human health: it is linked to obesity and correlated with various types of cancer. Plus the excessive light wastes $3B /yr!

The first court case when a self-driving car kills a kid wearing this t-shirt will be one for the history books. I can see the defense now: “The kid asked for it!”

Black Mirror episode in the making.

@ebagdasa The sun is also a star. Apparently very badly rated, also I didn't actually watch so can't say for myself either.

Selected a movie at random on the flight, and looked up to find an entire scene was set on Roosevelt Island!

Going to the annual conference always gives me a renewed appreciation of how operations research is such a wonderful field that works to bring improvements in all areas~ Also how great a department Cornell ORIE is!

[Amy B. Zhang @Amy_B_Zhang]

The blockchain seminar in fact had me thinking how the advantages of the technology seem to line up with major challenges faced by an NGO. Indeed there’re already existing use cases, which will be exciting to learn about, and hopefully prompt more potential applications.

[Amy B. Zhang @Amy_B_Zhang]

Great exposures in the past week at CornellTech: a panel about precision medicine in cancer care invited by https://t.co/dR2hNOB9BC, and a seminar on the use of blockchain in the financial markets given by Puneet Singhvi from Citi.

Just learned about a research initiative in China that uses ML to detect users of a platform who express suicidal tendencies, then initiates (very considerate) interactions. Their recent survey from thousands of intervened users was truly amazing to see! #WorldMentalHealthDay
