I wrote about attention, the mathematical operation that enables LLMs to process language at scale. Devised by Dzmitry Bahdanau in 2014, the trick was supercharged in the famous paper "Attention Is All You Need." I ask: 𝘞𝘩𝘺 is it all you need? Is it? quantamagazine.org/is-attent…

How much of published finance holds up?
I attempted to replicate the main result of every paper in JF, JFE & RFS, 2000–2020.
1,328 in-sample replications; 1,005 out-of-sample. 75% reproduced in sample. But only 42% in later data. Median coeff. : 0.93 → 0.45 of the published.

At long last, my paper with @poweill, @mahyarkargar, and Sebastian Plante is in print in the @JofFinance! A short thread on the paper… 1/n

Today #Bulgaria celebrates the Day of St. Cyril and St. Methodius as well as the creation of the Bulgarian alphabet commonly known as Cyrillic. Here is what happened /🧵

Today #Bulgaria commemorates the victims of the totalitarian Communist regime. For 45 years the Red terror altered the lives of over 1 million Bulgarians - from killing and torture to denying them work, education and meaningful social life. Never again!
Amazing, I will read with interest. I leafed through the Balkan crusades and the book seems to points to some initial root causes for the fall of the Balkans to the Ottomans such as the immense political fragmentation. Spot on, great work

This reminds me of an old Soviet joke (context: Cossacks were a prototypical “tough guy” in Soviet jokes).
A Soviet official from the city was visiting the far east and being shown around by a Cossack.
They run a red light.
The official asks the Cossack, why didn’t you stop?
Offended, the Cossack replies: we are a proud and strong people, why would we stop just because a light asks us to?
They keep driving, and then stop at a green light.
The official asks, why did you stop, the light is green?
The Cossack: oh we have to stop. There might be another Cossack driving through and we don’t want to get hit.
Nice illustration of equilibrium :)

На днешната дата, през 1886 г. България печели първата война в своята нова история, подписвайки Букурещкия договор. С него се приключва Сръбско-българската война. Тази победа гарантира опазването на Съединението и демонстрира пред Европа единството и силата на българския народ.
Честит празник!

Normally, it's:
1) write a paper & submit
3) get reviews (~3 months)
4) revise paper & resubmit
5) wait for response (~3 months)
...what if we could simulate this process in minutes?
Could we fix issues?
Anticipate misconceptions?
Get ideas for new analyses/experiments?

Днес е най-хубавия Български празник!
Факт е, че Кирилицата наричана още Българската азбука е създадена от учениците на светите братя,след смъртта им в земите на днешна Македония, тогава част от Българското царство. Създадена по заръка на Българския цар и подарена на вси Славяни!

For some clarity Petar Bogdan Bakshev (Petrus Deodatus) is a Bulgarian catholic Archbishop from the town of Chiprovtsi (northwest Bulgaria) who wrote the first Bulgarian 🇧🇬 history in Latin ca. 1667:
