Artificial Intelligence and Machine Learning Science and Technology Interest Group
The NASA Cosmic Origins Program AI/ML Science and Technology Interest Group (AI/ML STIG) addresses the critical need to upskill the astronomy community with AI literacy. We provide structured, domain-specific AI education through stackable, bite-sized modular training designed for astronomical research contexts.
About AI/ML STIG
Building AI Literacy for Astronomical Research
Astrophysics is an emerging technology for big-data science, and the use of Artificial Intelligence (AI) and Machine Learning (ML) technology will be inevitable in the coming decades.
The AI and ML Science and Technology Interest Group (AI/ML STIG) is motivated by the awareness that upskilling the scientific community could have a transformative impact to counter critical challenges facing astronomical research today.
By providing structured, domain-specific AI education, the AI/ML STIG aims to accelerate NASA's competitive advantage in AI-enabled space science, build the interdisciplinary workforce essential for next-generation astronomical discoveries, create a model for other NASA programs facing similar upskilling challenges, and establish NASA’s leadership in responsible AI adoption to maximize the science return from its missions by the community. The modular, community-driven approach ensures scalability while maintaining the rigor and domain relevance essential for meaningful scientific advancement. This STIG serves as a focal point for addressing these challenges through community townhalls for discussions and organizing short tutorials to address specific astronomical AI applications, modules, and foundational concepts.

News & Events
Meetings, conferences, seminars, workshops, and other news and events for the STIG
The Meaning of Understanding in AI-Laden Science. Speakers: Siyu Yao and André Curtis-Trudel. 4:00pm ET
Reinforcement Learning Fundamentals, Speaker: Carol Cuesta-Lazaro, IAS/Flatiron
A quick note: our speaker has had to cancel at the last minute due to an unexpected situation, so we'll take this week off. The good news is that next week we'll pick back up.
AI and Scientific Publishing. Speaker: Licia Verde, U. of Barcelona/JCAP
Simulation-Based Inference Speaker Tomasz Rozanski, ANU An introduction to simulation-based inference (SBI) for astronomy, using normalizing flows to perform posterior estimation in settings where the likelihood is intractable. Hands-on tutorials cover a toy physics problem and a stellar population application.…
Flow Matching Speaker Tomasz Rozanski, ANU A hands-on tutorial on flow matching for generative modeling in astronomy, covering continuous normalizing flows applied to stellar population modeling with both single and conditional population examples. Topics Covered Meeting Connection Join the Meeting
