Llama 3 is insanely moving fast.

People are really pushing Llama 3 to its limits in incredible ways.

10 wild examples (and use cases)

[Daniel Vila Suero @dvilasuero]

This is actually huge:

- No SFT stage (e.g., Zephyr used 200k examples)
- Preference tuning with 7K examples only (other models trained with at least 60k samples)

I've put a lot of care & love building the DPO version of the amazing Capybara dataset from @ldjconfirmed so I'm really pleased to see these results.

Let's double down on useful open data for OSS AI developers and researchers

Redefining Retrieval in RAG

A nice comprehensive study that focuses on the components needed to improve the retrieval component of a RAG system.

Confirms that the position of relevant information should be placed near the query. The model will struggle to attend to the information if this is not the case.

Surprisingly, it finds that related documents don't necessarily lead to improved performance for the RAG system. Even more unexpectedly, irrelevant and noisy documents can actually help drive up accuracy if placed correctly.

We need more systematic studies around RAG. The hard part of a RAG system is typically the retriever component. Just dumping relevant docs into the context is not an effective approach but it's what a lot of LLM devs do.

I like that the Ragas library proposes the use of several metrics for assessing a RAG system at both the generation and retrieval stages, including an end-to-end evaluation. It's a good first step but we still need better ways to integrate external information that can be effectively leveraged by the generative component.

@karpathy Cool! 💪 Looks like we share the same vision. Feel free to have a look at the preprint of our paper "Prompt-to-OS" which has been accepted at the Vision track of the next IEEE CogMI conf. A joint work with @gtolomei, @fabreetseo and @GioTrappolini.

Still can't handle the indecisiveness between Barbie and Oppenheimer? 😫💥 Don't fret!
Come to the presentation of our new perspective paper, "Multimodal Neural Databases", where we lay out the vision for database-like queries on multimodal data.

Three papers accepted at NeurIPS'22 (!!)

1) Efficiently training low-curvature neural networks (https://t.co/nL2FpxuNKh), w/ Kyle Matoba, @hima_lakkaraju, @francoisfleuret

We propose to build NNs that are "as linear as possible", and thus eliminate excess model curvature.
