Antarctic sea ice over the past 130 000 years – Part 2: A review of its role in the Earth system
Abstract. Antarctic sea-ice cover reached historically low levels in 2023, consistent with the simulated decline in sea-ice extent in response to anthropogenic warming. As Antarctic sea ice is closely...

Context Language Models New agent architecture where the LLM can edit its own context it seems to have emergent capabilities, creates its own memory management & organization algorithms, and coordinates multi agents github.com/facebookrese...
Diagram titled "How a Context Language Model edits its context: A simple step-by-step view" outlining an 8-step process:
 * Start of turn: Current editable context exists in memory with old messages.
 * LLM reads the context: The LLM evaluates the context and decides to run a bash command to edit it.
 * Harness mirrors context: The harness mirrors the old editable context into a file at /tmp/.live_ctx/LIVE_CTX_MAIN.txt.
 * Bash command runs: The bash command executes and may edit that file.
 * Harness parses file: If the file changed, the harness parses it back into a new edited context.
 * Tool call appended: The current assistant tool call is appended to the edited context.
 * Tool result appended: The tool result is appended below the tool call.
 * Next turn starts: The next turn begins with the edited old context, previous tool call, and previous tool result.
Key idea box: "The model edits the prior context first. The tool call and tool result from the current turn are appended afterward, so they can only be compacted on the next turn."
Footer summary:
 * Ordinary LM: Context mostly grows by appending.
 * CLM: The model can rewrite the editable part of context between turns.

1/n New paper - V-GIFT 🎁 Self-supervised tasks like rotation prediction or colorization were big in 2018. Do they still matter? Yes. We turn them into visual instruction tuning data for MLLMs. Result: models rely more on the image and perform better on vision tasks 👀

If you're training models with more than one loss term, I can again strongly recommend our ConFIG optimizer: tum-pbs.github.io/ConFIG/ , simply swap out Adam&Co. for ConFIG, and you can potentially see substantial reductions in your training loss 😁 We'd also be curious to hear how it works for you

Graph Transformers (GTs) can handle long-range dependencies and resolve information bottlenecks, but they’re computationally expensive. Our new model, Spexphormer, helps scale them to much larger graphs – check it out at NeurIPS next week, or the preview here! [1/13] #NeurIPS2024

A common question nowadays: Which is better, diffusion or flow matching? 🤔 Our answer: They’re two sides of the same coin. We wrote a blog post to show how diffusion models and Gaussian flow matching are equivalent. That’s great: It means you can use them interchangeably.
