Why?!? Why!? "To adjust for baseline confounding a pseudo-population was generated using propensity score overlap weighting. This created an emulated trial scenario ...." For the description ... it even doesn't account the time varying charact. of vax (GBM - PS) #episky

causal meditation folks. Help! I have a scenario in which Rcde / Rpnde / Rtnde are <1, and Rpnie/Rtnie >1 (way weaker than the direct ones). It's VAX (exp), infection (med), and MACE (outcome). I m struggling to interpret this. #episky #rstats

UC Berkeley Law creates new AI policy that bans AI for "conceptualizing, outlining, drafting, revising, translating, or editing any work submitted for credit" or exams because "thinking remains the sine qua non of good lawyering (and of a quality legal education)." That's what I'm talking about.

Rule:
The use of AI is prohibited for aid in conceptualizing, outlining, drafting, revising,
translating, or editing any work submitted for credit. AI use is prohibited for any use for
any purpose in any exam situation. Students may not upload course
materials—including assignments, readings, slides, class recordings, or other class
content—into generative AI systems. AI can be used for research on papers ONLY for the
limited purpose of identifying sources, such as cases, statutes, or secondary sources.
Students are responsible for the accuracy of their research and all other aspects of their
submitted work. Citations to sources that do not exist will raise a presumption of
prohibited AI use

I can only suggest to start noticing it as a first step. Time to stop the typical weird and gross habit of the whole world citing very specific USA scholars, when they never even read our work properly let alone cite it, but certainly benefit from it. Honestly, start ignoring these people. 3/

LLMs have entered the chat. And the guardrails are off. I've had the "pleasure" of seeing some R code that is clearly the result of some misguided prompt producing some very wrong and worse than useless results. This is bad. It's worse than "decision tree statistics", worse than not knowing. 4/

It might seem ridiculous for Nvidia to spend more on AI programming than it would cost to have humans to do the same programming. But it makes sense if you consider Silicon Valley's back-scratch culture, since spending on AI flows to other tech companies, who then funnel it back to Nvidia.

Headline: "The cost of compute is far beyond the costs of the employees:" Nvidia executive says right now AI is more expensive than paying human workers

Just read a comment: "... In my use, there is plenty of critical reasoning and direction by me in getting AI to do tasks that I want...." Is it like a gambler addict thinking they can direct the slot machines and they are learning techniques?

In a Brazilian self-controlled case series of 5055 hospitalizations for Guillain–Barré syndrome, laboratory-confirmed dengue was associated with an increased risk of Guillain–Barré syndrome occurring within 42 days. Learn more: nej.md/4cjXU8h
