As someone interested in formalism, I don't understand why logic textbook authors are so defensive about it. Like, “no, no, no, we are not the syntactic Taliban, we believe in mathematical truth.” Even when it is not necessary for what they are doing.
Fitness sites: Don't check your weight everyday.
Me: Without sufficient recent data on the noise process how can I ensure the optimality of my filter?
{I'm on the Terence Tao diet: An epsilon of calorie deficit. So efficient signal extraction is important.}
Since the common refinement of two axis-aligned partitions is itself an axis-aligned partition, any predictor based on a finite ensemble of decision trees can be replaced by a single decision tree.
I thought I was competent to teach Python. Then I was asked to explain this.
If A is 1×10, B is 10×50 and C is 50×1000, then (AB)C is much cheapter to calculate than A(BC).
Used this to argue why neural networks use reverse mode autodiff rather than forward mode (the matrices are the Jacobians of the layers).
Had a class on numpy and gave a lecture instead on clock frequency*ipc*simd and memory hierarchy. Who cares what it is calculating as long as you can make it go vroom :)
I want to pack all four months' data for a household from a CPHS wave into a single vector just so that I can call it a wave packet.
First draft of my lecture notes chapter what I find to be to the most difficult part of ML. The problem of induction. Would greatly appreciate comments. www.jyotirmoy.net/posts/2024-1...
Thanks to a work project, I discovered how expensive it is to control a touch monitor from more than 2m away. I'd have set up a remote desktop over WiFi and called it a day, but apparently it is considered too fragile by the pros. www.avaccess.com/products/4ke...
They are Eliza-fying Claude. Seeing a sharp uptick in the number of responses that end with a question to me. Must everything succumb at the altar of Engagement?
Hardbound book on desk, new translation of Karl Marx's 'Capital'
Got the new translation. At first sight the modernization of the language reads well, though I hope they have not smoothened away all of the old man's fire and brimstone. Paper too thin, print shows through @princetonupress.bsky.social
Agreed. I'm just saying that such a common and important function should have a short name. And giving it the name e will be neat as it represents e^. The only counterargument I can think of is that making function names longer makes them easier to visually distinguish from variables.
Avoiding cramped and ever-rising superscripts, which is why we have exp.
Wouldn't it be better to rename exp() to e()?
For the second time in my career, someone has tried to seriously insult me by saying that my research is more sociology than proper history.
I could never find that insulting.
Quite the opposite, actually.

Claude (new Sonnet) is fun to chat with, but it let me down again yesterday when I tried to do serious work with it, making errors in solving quadratic and linear equations, producing LaTeX that did not compile. Also the very smallness of the output size limit becomes a pain too quickly.
there are *surprisingly many* open problems when it comes to theory/methods in causal inference

Of course these are my early freshman level observations. Maybe more reading will show me how wrong I am being. (4/n)
These responses in the colonial period are also the subject matter of many of these works. But there seems to be very little self-reflexivity that they themselves are playing out a later act of the very drama that they are studying. (3/n)
One, trying to catch up and if possible beat the West at its own technology. Hence Theory. Two, trying to establish incommensurality to say that we were never in a race anyway. Hence Orientalism. (2/n)
I'm only now reading the PoCo-PoMo literature of the late 20th century — Partho Chatterjee, Ashish Nandy, Dipesh Chakrabarty etc — and finding it a hoot.
It seems to be a amalgam of the two fundamental Indian responses to Western superiority. (1/n)
I did a thread a year or so ago, on the bad site, about how marigolds were a late insertion into Hindu rituals (late = 15th-16th centuries).
Hindu nationalists hounded me for weeks over it.

CTRL (2024) is just sanitised Demonlover (2002).
Why aren't more people talking about the replication crisis in particle physics? How can the CERN people call themselves scientists when no one else in the whole world has even replicated their apparatus, to speak nothing of their results.
Give me a criteria for selecting subjects to be taught at the university which includes math but excludes astrology. Don't say usefulness, you'll offend many mathematicians.
First post
People from cultures where donuts are traditionally eaten: are you supposed to dunk them in coffee? I know there is a whole fast-food chain named after this, but it still does not seem like a good idea.
AJR getting the Nobel got me into a fight with friends about capitalism and colonialism. Now Wainwright and Vershynin are gathering dust and I'm trying to figure out 'What is History?'
They should have given the prize to Athey.
Interesting. I put the exact same thing on here and on Twitter. Ratio of likes to followers here is 1/200. Ratio of likes to rollowers on Twitter is 1/166, so very close. Folow me. I post about the JFE, some of my own work, complaints (and I'm usually funny when I'm pissed off), and food.
