This allows scPRINT zero-shot abilities -meaning no fine-tuning required- such as artificially increasing the depth of the expression profile of a cell (denoising / zero imputation), predicting the cell type, disease, sequencer, and sex of a cell, as well as creating cell embeddings 💪 .

But one of the key abilities we dived into is its inference of gene networks. We get inspired by ESM2 to design a way to extract gene networks from pre-trained transformers, which we call Large Cell Models. We extensively validate the gene network inference abilities of scPRINT, scGPT, and GENIE3, with our suite of benchmarking tools called BenGRN and GRnnData: https://t.co/FazHZYkzAO https://t.co/l9E2oFOvBj

Moreover, we don’t just release the code and the model weigths for scPRINT, but also its pre-training strategies, thanks to our dataloader and LaminDB’s new mapped dataset methods https://t.co/0wp5CsgUCK. https://t.co/JL9N3DdStx.

Taken together, the goal of these open source tools is to serve as a bedrock for future Large Cell Models developments. To improve -and possibly debug issues in- these transformer models by interrogating and benchmarking their abilities in a reproducible manner 🌍 👥.

We need to understand how the cell works but for that we need to know know what works and what doesn’t. This is my contribution to it. While still somehow a WIP, we have defined an extensive ablation study analysis with scPRINT that allows users to change. Models can be pre-trained on only one GPU for the small and medium size models and “only” 4 to 16 GPUs for the larger sized ones. 🚄

🏔️ The very large model is still undergoing training and testing. I am very happy to start building in public now and eager to see what the community will do with these tools. Do contact me if you would like to collaborate and have a try at the tool! I will provide more updates to the package and publish it on pypi in a week or so. But first.. a couple of days off! 🌴☀️ 🫡

🙏🙏🙏 I would like to thank additional collaborators from laminDB, as well as members of the Cantini Lab and Peyré Lab: @JulesSamaran , @TrimbourR , @gjhuizing , Anna Audit and @wariobrega. But most of all, my 2 great P.I.s: @LauCan88 and @gabrielpeyre 🇫🇷 🎓

💯 🙏 Also, I would like to acknowledge the important pioneering work from Geneformer, UCE, scFoundation and scGPT. Thanks to FlashAttention, pytorch, lightning, and scanpy for their toolkits. Thanks to Omnipath, Scenic+, Openproblems, Replogle et al. and Mc Calla et al. for their ground truths and benchmarking tools (all links and citations are in the paper).

Exciting new blog -- What’s up with Llama-3?

Since Llama 3’s release, it has quickly jumped to top of the leaderboard. We dive into our data and answer below questions:

- What are users asking? When do users prefer Llama 3?
- How challenging are the prompts?
- Are certain users or prompts over-represented?
- Does Llama 3 have qualitative differences that make users like it?

Key Insights:
1. Llama 3 beats top-tier models on open-ended writing and creative problems but loses a bit on close-ended math and coding problems.

[Thomas Scialom @ThomasScialom]

We had a small party to celebrate Llama-3 yesterday in Paris! The entire LLM OSS community joined us with @huggingface, @kyutai_labs, @GoogleDeepMind (Gemma), @cohere
As someone said: better that the building remains safe, or ciao the open source for AI 😆

[Arena.ai @arena]

Moreover, we observe even stronger performance in English category, where Llama 3 ranking jumps to ~1st place with GPT-4-Turbo!

It consistently performs strong against top models (see win-rate matrix) by human preference. It's been optimized for dialogue scenario with large amount of instruction data in post-training.

More analysis still ongoing with topic distribution and agreement study. We also look forward to details in Llama-3's technical report.

[Arena.ai @arena]

Exciting update -- Llama-3 full result is out, now reaching top-5 on the Arena leaderboard🔥

We've got stable enough CIs with over 12K votes. No question now Llama-3 70B is the new king of open model. Its powerful 8B variant has also surpassed many larger-size models. What an incredible launch!

Huge congrats to Llama team at @AIatMeta and for such valuable contribution to open community! Can't wait to see the 400B.

[AI at Meta @AIatMeta]

Introducing Meta Llama 3: the most capable openly available LLM to date.

Today we’re releasing 8B & 70B models that deliver on new capabilities such as improved reasoning and set a new state-of-the-art for models of their sizes.

Today's release includes the first two Llama 3 models — in the coming months we expect to introduce new capabilities, longer context windows, additional model sizes and enhanced performance + the Llama 3 research paper for the community to learn from our work.

[CL] Language Evolution with Deep Learning
M Rita, P Michel, R Chaabouni, O Pietquin, E Dupoux, F Strub [INRIA & Google DeepMind] (2024)
https://t.co/yKz8saxRfU

- Deep learning is well-suited for simulating communication games and studying language emergence and evolution.

- Communication games can be formalized as a multi-agent machine learning problem where agents are represented by deep neural networks.

- Communicative agents are designed using functional modules: perception, generation, understanding, and action. Neural networks can be used to model these modules.

- Various neural architectures like MLPs, CNNs, RNNs and Transformers can be used to implement the agents' modules depending on the input data type and task.

- Optimization techniques like supervised learning and reinforcement learning are used to train the agents to develop a shared communication protocol and solve the game.

- The Visual Discrimination Game is a common case study in emergent communication research with neural agents.

- Recent work has explored more realistic simulations beyond simple referential games, such as embodied agents in 2D worlds.

- Despite successes, current simulations have limitations in realism and the languages that emerge are still far from natural languages.

Meta presents SpiRit-LM

Interleaved Spoken and Written Language Model

paper page: https://t.co/ESqeR4BzYu

introduce SPIRIT-LM, a foundation multimodal language model that freely mixes text and speech. Our model is based on a pretrained text language model that we extend to the speech modality by continuously training it on text and speech units. Speech and text sequences are concatenated as a single set of tokens, and trained with a word-level interleaving method using a small automatically-curated speech-text parallel corpus. SPIRIT-LM comes in two versions: a BASE version that uses speech semantic units and an EXPRESSIVE version that models expressivity using pitch and style units in addition to the semantic units. For both versions, the text is encoded with subword BPE tokens. The resulting model displays both the semantic abilities of text models and the expressive abilities of speech models. Additionally, we demonstrate that SPIRIT-LM is able to learn new tasks in a few-shot fashion across modalities (i.e. ASR, TTS, Speech Classification).

[Baptiste Rozière @b_roziere]

We released a 70B version of CodeLlama today! Trained on 1T tokens, it is a much stronger base model for coding tasks. I look forward to seeing what the community will do with it! :)
