Privacy is at the core of everything we do, and #GoogleHealthStudies protects information in a few important ways — learn more: https://t.co/rJlEtDcVK4

We conducted cyber evaluations of Claude Mythos Preview and found that it is the first model to complete an AISI cyber range end-to-end. 🧵

When I was younger, I always worshiped people who could find the right solution to a difficult problem. But now I've realized that it is so much harder and so much more important to find the right problem to work on, even if you cannot find a solution yet.

Health experts worry as Meta rolls back some COVID misinformation policies https://t.co/uJGZSs7maT

@johnbrownstein: "One of the biggest challenges we faced with the pandemic... was not the virus itself but it was the #misinformation that was generated around the science..."

Nothing but respect. Thank you!

Professor Strang gave his last Linear Algebra lecture today after 66 years at MIT.

Strang was among the first to upload his classes to MIT OpenCourseWare when it first came online in the early 2000s. His 18.06 lectures have been viewed millions of times around the world

Every economist I know says that it takes 15 to 20 years before a new general purpose technology has a measurable effect on productivity.
The delay is determined by how fast people learn to use it.

So no, AI is not going to cause instant mass unemployment.

It's going to displace jobs over time and make people more productive, just like every other technological revolution before that.

Because intelligence is the primary (maybe only) survival advantage of homo sapiens, we may have evolved hard-wiring to value it over all other capabilities in nature. Perhaps partly why we are fascinated, and discomforted, by AI. And why we think it must be highly complex.

[Gaurav Tuli, PhD @_gtuli]

Rightly pointed out and said!

My new favorite thing - Bing's new ChatGPT bot argues with a user, gaslights them about the current year being 2022, says their phone might have a virus, and says "You have not been a good user"

Why? Because the person asked where Avatar 2 is showing nearby

Concerning uptick of wastewater monitoring by @BiobotAnalytics.
Time for the CDC to integrate #wastewater analysis in guidance to the public.
Time to accelerate the distribution of tests, masks, and vaccines.

@MauSantillana @NUnetsi @Northeastern Many more congratulations, Mauricio🎉 You are a rockstar and your work always has high betweenness centrality no matter the group or university you join :)

Lol. Most of #asia is eating the Italian food wrong. Especially, on the things unacceptable to Italians. #pizza #dataviz

@samarth_swarup happy Thanksgiving! Waiting for your yearly post :)

Temporal bias serves to amplify differences between the case (e.g. disease) and control (e.g. healthy) populations, improving apparent predictive accuracy and exaggerating effect sizes of predictors. reductio ad absurdum example: pregnant/non-pregnant See details in 2/

@adhigunamahend1 @burkov @adhigunamahend1
That means, one way to avoid concept shift is to NOT use static ranges for cardinal to ordinal var conversions (eg., 50K<= midincome<100K) while reducing dimensionality etc. USE dynamic quartiles instead?? #MachineLearning

The CDC has officially recommended the vaccine for kids over five. 28 million children can now get vaccinated against covid-19! What a day
