Rewarding Chatbots for Real-World Engagement with Millions of Users
Robert Irvine, Douglas Boubert, Vyas Raina +11
The emergence of pretrained large language models has led to the deployment of a range of social chatbots for chitchat. Although these chatbots demonstrate language ability and flu…
The Photo-Astrometric Vertical Tracer Density of the Milky Way II: Results from Gaia
Andrew Everall, Vasily Belokurov, N. Wyn Evans +2
We use Gaia photometry and astrometry to estimate the vertical spatial structure of the Milky Way at the Solar radius, formally accounting for sample incompleteness (the selection…
The Photo-Astrometric Vertical Tracer Density of the Milky Way I: The Method
Andrew Everall, N. Wyn Evans, Vasily Belokurov +2
We introduce a method to infer the vertical distribution of stars in the Milky Way using a Poisson likelihood function, with a view to applying our method to the Gaia catalogue. We…
Completeness of the Gaia-verse V: Astrometry and Radial Velocity sample selection functions in Gaia EDR3
Andrew Everall, Douglas Boubert
We risk reaching false scientific conclusions if we test our physical theories against subsets of the Gaia catalogue without correcting for the biased process by which stars make i…
A selection function toolbox for subsets of astronomical catalogues
Douglas Boubert, Andrew Everall
Large catalogues are ubiquitous throughout astronomy, but most scientific analyses are carried out on smaller samples selected from these catalogues by chosen cuts on catalogued qu…
Selection Functions in Astronomical Data Modeling, with the Space Density of White Dwarfs as Worked Example
Hans-Walter Rix, David W. Hogg, Douglas Boubert +6
Statistical studies of astronomical data sets, in particular of cataloged properties for discrete objects, are central to astrophysics. One cannot model those objects' population p…
