As a native of CT, I can tell you that there's lots of things about the state that are very annoying (most notably the traffic). Rosa DeLauro, however, is a treasure
Rep. Rosa DeLauro: "On the food stamp issue, the money is there! Let them not get away with saying they can't do it. Their political will isn't there to feed the people who rely on the SNAP program which is the most effective anti-hunger program in the USA."

We wrote here why we shouldn't even call such unprincipled data dredging or fishing for statistically significant effects "exploratory research". It's time we start taking scientific exploration seriously. Again.

We wrote an article explaining why you shouldn't put several variables into a regression model and report which are statistically significant - even as exploratory research. bmjmedicine.bmj.com/content/4/1/.... How did we do?

Been going through my old machine learning books, and, especially in books on neural networks, you see language like this. The machine "learns weights.." etc. Yet, fitting a maximum likelihood solution iteratively, or using MCMC to for Bayes is the same idea, but no such "learning" metaphor
Chatbots — LLMs — do not know facts and are not designed to be able to accurately answer factual questions. They are designed to find and mimic patterns of words, probabilistically. When they’re “right” it’s because correct things are often written down, so those patterns are frequent. That’s all.

One of the more concerning aspects of this is how long it will take for the new ballroom to be usable and what that says about how long Trump plans to be able to use it
President Trump is plowing ahead with plans to build a grand ballroom where the East Wing of the White House currently stands. The plans have not gone through the committee tasked with overseeing such projects.
The East Wing could fully be demolished soon, as preservationists urge caution

I’ve been reading some old neural networks texts and one thing that strikes me is the vast difference between a problem like optical character recognition and that of clinical prediction models. The former problem being relatively well-defined with synthetic examples easily produced.

Anyway Hakeem Jeffries and Chuck Schumer are both New Yorkers and the top Democrats in the House and Senate, respectively, and any point they could learn how to use a shutdown to make the point that we’re living in fascism.
