I want to show the NSF there would be broad support+utility for a "National Deep Inference" service for >100b LLMs.

If your research would be enabled by an inference service on open LLMs w API access+overrides to internal activations, params, gradients: please boost this thread!

(I'm also gathering feedback on twitter - more details here:)

I have put together a curated list of about 50 papers that (IMO) were seminal in defining what "Deep Learning" is today, to share with my students. Goes from 1943-2022.

https://papers.baulab.info/00_README.html

Question for the AI fediverse: What is missing off this list that should be on it?

Had a great time meeting people at #BlackboxNLP and #EMNLP2022 last week. You can see my talk as well as great talks by Lena Voita and Catherine Olsson on youtube here:

OK, I get it now: the "Federated" feed shows all posts that people on my local server follow

https://techcrunch.com/2022/11/08/what-is-mastodon/#:~:text=that%20people%20in%20your%20server%20follow

I am switching to sigmoid.social. The federated feed here is way more interesting to me than my original random server.

Replying to
@boazbaraktcs Yes I also think that, just the mechanics of having a good setup to deal with the practical aspects of working with unwieldy large models, in a research setting, will be important. It will make a big difference if it becomes easy and routine.

Replying to
@boazbaraktcs yes, agreed, lightweight fine-tuning or techniques like soft-prompts need to be accssible. Seems like such iterated or batch use-cases are a 2nd tier of service; you might be willing to wait longer for results.

@wattenberg@mastodon.social

I have tried the first few steps of the prompts in this article.

I can confirm that GPT can define a language along with conjugations and do basic translations applying the words and rules that are set out.

Ok, wow.

As the 2022 US election results are finalized, @arnab_api@twitter.com and Jaden Fiotto-Kaufmann have been directly loading memories of the new officeholders into GPT-J. Find it here: https://election-memit.baulab.us/#/ It demonstrates the MEMIT method https://twitter.com/mengk20/status/1588581237345595394?s=20&t=WVgviK2JGyAqJ3SEIKs-XA

How & where do large language models (LLMs) like GPT store knowledge? Can we surgically write *new* facts into them, just like we write records into databases? Explainer 🧵 on how interpretability & model editing go hand-in-hand, and why these emerging areas are so important 👇

My student Rohit Gandikota is finding that large diffusion models like SDXL can be controlled very precisely with low-rank changes in parameters.

His twitter thread on "Concept Sliders" is also a great survey of current diffusion model controllability work. The nice thing about modern image synthesis is that the results are gorgeous.

Help him spread the word!

Have you ever wanted to make a precise change when generating images with diffusion models?🎨 We present Concept Sliders, which enable smooth control to create your vision, fix common problems, and a "fix hands" sliders too. Here's an explainer on how sliders work🧵

My student Koyena Pal will be presenting some cool work at #CoNLL2023.

Her Future Lens (https://future.baulab.info) can look a single hidden state of an LLM and see what a transformer is planning, several tokens ahead.

It can make reading the internal states much more intuitive!

Look for us if you'll be in Singapore for EMNLP/BlackboxNLP/CoNLL.

Work with Jiuding Sun, Andrew Yuan, and Byron Wallace.

#LLMs are trained to predict the next word. But we found that they are overachievers! When GPT-J is busy predicting the next word, our Future Lens (https://t.co/KF8qOBAbkd) sees that it's already thinking several words ahead – see "Back to the Future" below... #CoNLL2023 🧵 1/8

Eric Todd has a really interesting new preprint on arXiv:

https://functions.baulab.info

He shows LLMs contain vector representations of functions that compose and apply in diverse contexts.

It could be a powerful tool for understanding reasoning mechanisms within LLMs.

Eric explains more on a twitter thread here

https://x.com/ericwtodd/status/1717277426873766104?s=20

It's his paper of his PhD. Help him spread the word!

LLMs represent words as vector embeddings. Do they represent *functions* as vectors too? Yes! This has implications for how we think about “reasoning” in language models. New preprint w/ @millicent_li, @arnab_api, @amuuueller, @byron_c_wallace, @davidbau: https://t.co/NCsbctXpMq

People are speculating, "it's over." If so: what a strange way to close down a major property.

I will be at #Neurips2022 this week! Reach out to me to connect+chat about mechanisms in LLMs, AI alignment, knowledge, privacy, image synthesis, interpretability. And Wed PM (Session 4 Hall J #226) find Kevin's poster on editing GPT https://neurips.cc/virtual/2022/poster/53864 https://twitter.com/mengk20/status/1588581237345595394

@jcorgan Yeah! The idea of a neural network is almost as old as the idea of a computer.

@jcorgan Notorious, but, IMO still worth a read today. With all the magic being pulled off by finite-input networks like Transformers today, it makes you wonder: have we ever really resolved the computability question that Minsky+Papert raised decades ago?
