📢 New dataset out! We introduce HypoGen💥, a dataset of ~5.5K structured problem–hypothesis pairs (Bit–Flip–Spark + Chain‑of‑Reasoning) to advance LLM-driven scientific ideation💡. Fine‑tuned LLaMA 3.1 8B & R1‑distilled models show significant gains. Humans are still the best🥇.

Our two-stage fine-tuning process adapts the model for both image captioning and visual question answering in the astronomy domain, making complex astronomical concepts more accessible through natural conversation

We fine-tuned LLaVA on ~30k astronomical images with captions & QA pairs from NASA APOD, ESO, and Hubble archives to create a model that understands astronomical concepts in visual form 👉 hf.co/datasets/UniverseTBD/AstroLLaVA_convos

🎉 HAPPY BIRTHDAY, UniverseTBD! 🚀 As we turn 2, we’re going 2^2. Launching a new project per day for the next four days. We hope that you all enjoy these works as much as we have enjoyed working on them. Stay tuned for the big reveals!

This work wouldn't have been possible without collaboration between more than two dozen researchers and institutions 👇

The MMU compiles crossmatched observations of astronomy's most important telescopes, including: - over 120M galaxy images - over 5M stellar and galactic spectra - Light curves for over 3.5M astronomical objects - Measurements of nearly 220M stars - Supernova and galaxy classifications

Excited to announce the Multimodal Universe (MMU): a huge 100TB dataset bringing together the largest ML-focused collection of astronomical observations ever assembled to accelerate open AI and astronomy research github.com/MultimodalUn... Think ImageNet, but for space 🔭 #astrocode 🧵

Join us on Discord tomorrow (Nov 28th) at 15:00 UTC for our monthly talk 🔭 🧪 ! @micginolfi.bsky.social (U Florence) will be talking about how we can infer many galaxy properties via a single neural net (nice X thread here with more details: x.com/micginolfi/s...). Link: discord.gg/9PXcTH7cTn?e...
