Volodymyr Zelensky is NOT a dictator. Vladimir Putin IS a dictator. Zelensky didn’t start the war in Ukraine. Putin did. Hope this clarifies things for anyone who is confused.

Finally, in frustration, I asked if it could write a regex to find all occurrence of the bracketed numbers in the output. It got the regex wrong. What's going on here? I feel like the emperor has no clothes. Are people solely using these tools to write boilerplate? (10/10)

I hope I'm wrong, and that there's something I'm not seeing, but as far as I can tell, this appears to be a craven and somewhat pathetic bid from the Nobel committee to capitalize on AI hype by arbitrarily changing their standards, and I find it all rather distasteful. (6/6)

Even though it’s rather outside my area of expertise, «On the Independence Assumption in Neurosymbolic Learning» by @EmilevanKrieken and @PMinervini communicates and leaves the proofs in the paper. #ICML2024

[CL] The Geometry of Categorical and Hierarchical Concepts in Large Language Models K Park, Y J Choe, Y Jiang, V Veitch [University of Chicago] (2024) arxiv.org/abs/2406.01506 - The paper studies how categorical concepts like {mammal, bird, reptile, fish} and hierarchical concepts like animal vs mammal are represented in large language models. - It extends the linear representation hypothesis, which says high-level concepts are linearly encoded, from binary concepts to categorical and hierarchical concepts. - It shows categorical concepts are represented as simplices, with vertices corresponding to binary features like mammal, bird, etc. - It shows hierarchical concepts are encoded through orthogonality. For example, the representations of animal and mammal are orthogonal. - It validates these theoretical results empirically on the Gemma large language model, estimating representations for 957 hierarchically related concepts from WordNet.

Kharkiv, Ukraine's 2nd largest city, is under relentless missile and Shahed drone attacks, mercilessly targeting innocent civilians. In just the past weeks, these barbaric assaults have taken the lives of at least 15 people, leaving countless others wounded, including vulnerable children. Ukraine urgently requires additional air defense systems to shield its citizens. Every second counts. #UkraineNeedsAirDefense
