Background

Following on from Tony's scistaff meeting about Astronomy AI institutes in August 2023, we decided it would be good to set up a regular (~monthly) series of meetings on using AI/ML focused especially on VLASS, which, as it produces a large, uniform set of images and other products makes it a good candidate for this sort of work, but also covering other areas e.g. science ready data products, pipeline QA etc, particularly with an eye towards what will be needed for ngVLA.

Aim

To draft a white paper/VLASS memo on these topics (on a timescale ~ 1 year) and, if we find some particularly compelling use cases, to include an implementation plan, an estimate of the resources needed to carry it out and outreach to possible partners from the NSF's AI institute effort.

Resources

There exists a rich literature of astronomical uses of AI/ML, here are some interesting papers/talks that might be relevant. See also this set of PASP papers on machine learning in astronomy
