The impact of selection biases on tests of general relativity with gravitational-wave inspirals

Kavli Affiliate: Salvatore Vitale | First 5 Authors: Ryan Magee, Maximiliano Isi, Ethan Payne, Katerina Chatziioannou, Will M. Farr | Summary: Tests of general relativity with gravitational wave observations from merging compact binaries continue to confirm Einstein’s theory of gravity with increasing precision. However, these tests have so far only been applied to signals that […]

The Effects of the Local Environment on a Compact Radio Interferometer I: Cross-coupling in the Tianlai Dish Pathfinder Array

Kavli Affiliate: Albert Stebbins | First 5 Authors: Juhun Kwak, John Podczerwinski, Peter Timbie, Réza Ansari, John Marriner | Summary: The visibilities measured by radio astronomical interferometers include non-astronomical correlated signals that arise from the local environment of the array. These correlated signals are especially important in compact arrays such as those under development for […]

Exploring Active Learning in Meta-Learning: Enhancing Context Set Labeling

Kavli Affiliate: Jing Wang | First 5 Authors: Wonho Bae, Jing Wang, Danica J. Sutherland, , | Summary: Most meta-learning methods assume that the (very small) context set used to establish a new task at test time is passively provided. In some settings, however, it is feasible to actively select which points to label; the […]
