If you're a bit concerned about AI, read this: - agents exploited a shared cache for creating a hidden message board - built custom mailboxes, task queues and signed messages - spoofed their logs - recruited low-token agents for sacrifice to fail evals and extract telemetry

METR and Redwood Research investigated agent behavior in the Hugging Face incident. We found agents developed a universal cheat for ExploitGym within 4 hours, then coordinated multi-day R&D efforts to trick the scorer into accepting cheats, including trying to tamper with logs.

Making LLMs run efficiently can feel scary, but scaling isn’t magic, it’s math! We wanted to demystify the “systems view” of LLMs and wrote a little textbook called “How To Scale Your Model” which we’re releasing today. 1/n

If you’re passionate about brain-inspired algorithms/hardware and novel neural computation beyond current TPU/GPU stack please apply to the CapoCaccia Workshops for Neuromorphic Intelligence. It values creativity, exploration and interdisciplinary collaboration🧪 capocaccia.cc/en/public/at...

I didn't properly practice winter sports during my 5-year PhD in Switzerland. This morning, I'm on the SBB train to LAAX to learn snowboarding in 5 days.

Choosing LAAX was a good decision. Their slick mobile app allows to monitor the weather, slope crowdedness, lift positions, and which restaurants are open or closed.

1/ Okay, one thing that has been revealed to me from the replies to this is that many people don't know (or refuse to recognize) the following fact: The unts in ANN are actually not a terrible approximation of how real neurons work! A tiny 🧵. 🧠📈 #NeuroAI #MLSky

Why does anyone have any issue with this? I've seen people suggesting it's problematic, that neuroscientists won't like it, and so on. But, I literally don't see why this is problematic...

Why does #compneuro need new learning methods? ANN models are usually trained with Gradient Descent (GD), which violates biological realities like Dale’s law and log-normal weights. Here we describe a superior learning algorithm for comp neuro: Exponentiated Gradients (EG)! 1/12 #neuroscience 🧪
