@harryjwang Not very long from now, these tools will be seen as barriers to the field. Will be there for the “I told you so”

Where are theee

[Anthropic @AnthropicAI]

We’re expanding our partnership with @Accenture to help enterprises move from AI pilots to production.

The Accenture Anthropic Business Group will include 30,000 professionals trained on Claude, and a product to help CIOs scale Claude Code.

@xwang_lk @ucsbNLP Any Post-doc openings? Asking for a friend

[Rehan Ahmed, PhD @_rehan_a]

@ljyflores38 @Adobe Nice work. Any plans of releasing the benchmark?

Great paper on how Google runs a commercial research lab, courtesy of Ankush Menat.

Would love to read more like this particularly from young and actively growing companies (i.e. don't send me Oracle or Bell Labs).

After Ethan's post, I went on a deep dive into this study! I could go on and on about the results but if I had to boil it down to my biggest takeaways...🧵

[Ethan Mollick @emollick]

New randomized, controlled trial of students using GPT-4 as a tutor in Nigeria. 6 weeks of after-school AI tutoring = 2 years of typical learning gains, outperforming 80% of other educational interventions.

And it helped all students, especially girls who were initially behind

This paper from DeepMind is blowing my
mind:

“Our findings reveal that models fine-tuned on weaker & cheaper generated data consistently outperform those trained on stronger & more-expensive generated data across multiple benchmarks…”

📢 Check out the lineup of papers our students will be showcasing at #EMNLP2024 in Miami next week! 🌴We'll be presenting new work on morphology, Q&A, and narratives.🔍

Why and when do preference annotators disagree? And how do reward models + LLM-as-Judge evaluators handle disagreements?

We explore both these questions in a ✨new preprint✨ from my @allen_ai internship!

There's a general feeling that AI-written text is repetitive. But this repetition goes beyond phrases like "delve into"! We can actually characterize repetition at a structural level using syntactic templates... 🧵

Hitchhiker's guide to rebranding:
- Machine learning -> statistical mechanics
- Loss function -> energy functional
- Optimize the model -> minimize free energy
- Trained model -> reached equilibrium distribution
- KL divergence -> free energy difference
- Gaussian noise -> random thermal fluctuations
- Random step -> Brownian motion
- SGD -> directional Brownian motion
- GPU -> simulated particle accelerator
- Diffusion models -> Langevin dynamics
- Reinforcement learning -> control theory
- Robotics -> physical computation
- Audio learning -> 1D signal processing
- Image learning -> 2D signal processing
- Video learning -> 3D signal processing
- Multimodal models -> multidimensional signal processing
- Sora -> learned physics engine

You're welcome
