Fun challenge that is apparently hard for LLMs (at least all those I could get my hands on): solving carefully drafted anagrams! New ARC challenge? :D PS: credits go to family Lehmann from Kassel who invent those ridiculously hard Xmas puzzles every year!

Segment radixsort, prefixsums and pointwise transforms are just OPed on GPUs. The amount of throughput you can get on a single cheap device is ridiculous! And you can implement so much crazy stuff with just that. ❤️

I’ll be at NeurIPS next week –happy to connect! Hit me up if you’d like to meet up and chat :) (tabular deep learning; in-context learning; SSL; AI in EU; politics; where to get good coffee/food; your favourite Parks and Rec moment; …)

The link between diffusion models and optimal transport is still a bit of an enigma to me. One thing that's clear: different diffusion models trained on similar datasets tend to recover similar mappings. If these are generally not OT, in what sense are they optimal instead?

I wrote a summary of the main ingredients of the neat proof by Hugo Lavenant that diffusion models do not generally define optimal transport. github.com/mathematical...

What this misses is that major changes that Elon made changed it from an open forum to an extremely distorted two-tier system - primarily boosting bluecheck replies to the top of every interaction. People with different beliefs can come here too, but they'll interact on a more level field.

Opinion - The problem with Bluesky: It won’t broaden our horizons: In the wake of Donald Trump’s election win, the social-media platform has enjoyed a surge of new users looking for an alternative to Elon Musk’s X. But will it be useful, if it just creates an echo chamber for the left?
