Projects, Talks, and Writing

Big Radio Telescopes and Big Radio Galaxies

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.

Data challenges in citizen science

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.

Machine learning for radio cross-identification

Alger, M. J.; Banfield, J. K.; Ong, C. S.; Rudnick, L.; Wong, O. I.; Wolf, C.; Andernach, H.; Norris, R. P.; Shabala, S. S.

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.

I trained a classifier and now I don’t know what to do with it

Using classifiers for things that aren't classification. A talk presented at the 2017 Mount Stromlo Student Seminars at the Australian National University.
