Kaggle competition for "Airborne Object Recognition Challenge"

@kaggle.com seriously? Are you really hosting an "object recognition" challenge with classes which include "plane,drone,human,ship" and goals which include "identifying objects of interest in operational contexts"?

๐ŸงตNew paper: "Lost in Backpropagation: The LM Head is a Gradient Bottleneck"
The output layer of LLMs destroys 95-99% of your training signal during backpropagation, and this significantly slows down pretraining ๐Ÿ‘‡

In light of the current funding situation (worldwide), a modest proposal: instead of pouring billions of dollars into GenAI claiming "it *could* accelerate science and research," consider putting 1% of that amount in what *will* accelerate science and research. Namely, funding science and research.

I would grab this opportunity and go full VC; I would rephrase the above as multi-label classification with labels: possible / sensical / dystopian and require that the candidates shatter the AI startups

Tiles for three authors on Overleaf that spell out "ALE", as in beer.

The best feature of overleaf is the subliminal messages it produces by choosing how to order the author tiles.

It was a long day, and Overleaf was like, maybe you should go to the pub!
