Astronomy today is in an exciting and challenging era with the fast-increasing amount of data from large-scale sky surveys and future facilities.
- the Sloan Digital Sky Survey (SDSS) founded in 2000 has observed ~50 million galaxies,
- the Dark Energy Survey has found over 300 million galaxies since starting its observation in 2013, and in the near future,
- the Vera C. Rubin Observatory will carry out an astronomical survey to observe ~20 billion galaxies.
This accelerates the development of machine learning (ML) and artificial intelligence (AI) in astronomical studies.
In this talk, Sunny will give an overview of how astronomers react to the plethora of astronomical data and how ML and AI help improve conventional analyses in various aspects,
as well as inspire new perspectives to look into data in galaxy studies.
Hopefully see you all at the Wetlands Centre (Discovery Room) , Raffle & Refreshments as usual.
