Early-science data from the Australian Square Kilometre Array Pathfinder (ASKAP) are coming fast. Wide-area radio projects such as the Evolutionary Map of the Universe (EMU) and the Polarisation Sky Survey of the Universe’s Magnetism (POSSUM) already have terabytes of ASKAP observations for use in early-science and survey planning. In this talk presented at C3DIS 2019 in Canberra and AI in Astronomy at ESO (Garching), I explain how I found a meaningful feature representation for prediction on early-science observations.
Legacy wide-area radio surveys have much science to offer, if we can get useful data out. I developed a machine learning approach to cross-identifying a large number of radio sources, and used this to make radio luminosity functions.
I conduct a comical critical analysis on the talk immediately preceding mine at the 2019 Stromlo Student Seminars (itself by Adam Rains).
Next-generation radio telescopes will change radio astronomy. But what are next-generation radio telescopes? And what do we see in the radio sky? A talk presented at Smith's Alternative for the ANU Astronomy Society.
I discuss the science of Sailor Scouts in this comedy talk for the Stromlo Student Seminars 2018.
How does sourcing data from citizen science affect model validation? A talk presented at the Collaborative Conference on Computational and Data Intensive Science 2018 at the Melbourne Conference and Exhibition Centre.
We present a machine learning approach for the task of determining the infrared host galaxies of radio emissions detected in wide-area radio surveys. Our method is trained on both expert cross-identifications and crowdsourced cross-identifications from Radio Galaxy Zoo and applied to observations from the Australia Telescope Large Area Survey.
Using classifiers for things that aren't classification. A talk presented at the 2017 Mount Stromlo Student Seminars at the Australian National University.
