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

  • Introduction to flow matching and continuous normalizing flows
  • Vector fields and optimal transport
  • Single population modeling of stellar properties
  • Conditional flow matching for population-dependent generation
  • Applications to isochrone and stellar catalog generation

Angled from the upper left corner to the lower right corner is a cone-shaped orange-red cloud known as Herbig-Haro 49/50. This feature takes up about three-fourths of the length of this angle. The upper left end of this feature has a translucent, rounded end. The conical feature widens slightly from the rounded end at the upper right down to the lower right. Along the cone there are additional rounded edges, like edges of a wave, and intricate foamy-like details, as well as a clearer view of the black background of space. In the upper left, overlapping with the rounded end of Herbig-Haro 49/50, is a background spiral galaxy with a concentrated blue center that fades outward to blend with red spiral arms. The background of space is speckled with some white stars and smaller, more numerous, fainter white galaxies throughout.
