Mitigating Closed-model Adversarial Examples with Bayesian Neural Modeling for Enhanced End-to-End Speech Recognition

Posted by klaurent Stanford

Kavli Affiliate: Zeeshan Ahmed | First 5 Authors: Chao-Han Huck Yang, Zeeshan Ahmed, Yile Gu, Joseph Szurley, Roger Ren | Summary: In this work, we aim to enhance the system robustness of end-to-end automatic speech recognition (ASR) against adversarially-noisy speech examples. We focus on a rigorous and empirical "closed-model adversarial robustness" setting (e.g., on-device or […]

Massive Galaxy Mergers Have Distinctive Global HI Profiles

Posted by klaurent Peking

Kavli Affiliate: Jing Wang | First 5 Authors: Pei Zuo, Luis C. Ho, Jing Wang, Niankun Yu, Jinyi Shangguan | Summary: The global 21 cm HI emission-line profile of a galaxy encodes valuable information on the spatial distribution and kinematics of the neutral atomic gas. Galaxy interactions significantly influence the HI disk and imprint observable […]

Observation and origin of non-thermal hard X-rays from Jupiter

Posted by klaurent MIT

Kavli Affiliate: Melania Nynka | First 5 Authors: Kaya Mori, Charles Hailey, Gabriel Bridges, Shifra Mandel, Amani Garvin | Summary: Electrons accelerated on Earth by a rich variety of wave scattering or stochastic processes generate hard non-thermal X-ray bremsstrahlung up to >~ 1 MeV and power Earth’s various types of aurorae. Although Jupiter’s magnetic field […]

Reassessing the Evidence for Time Variability in the Atmosphere of the Exoplanet HAT-P-7 b

Posted by klaurent MIT

Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Maura Lally, Andrew Vanderburg, , , | Summary: We reassess the claimed detection of variability in the atmosphere of the hot Jupiter HAT-P-7 b, reported by Armstrong et al. (2016). Although astronomers expect hot Jupiters to have changing atmospheres, variability is challenging to detect. We looked for […]

Modular Products and Modules for Finite Groups

Posted by Chicago

Kavli Affiliate: Jeffrey A. Harvey | First 5 Authors: John F. R. Duncan, Jeffrey A. Harvey, Brandon C. Rayhaun, , | Summary: Motivated by the appearance of penumbral moonshine, and by evidence that penumbral moonshine enjoys an extensive relationship to generalized monstrous moonshine via infinite products, we establish a general construction in this work which […]

Spectral sirens: cosmology from the full mass distribution of compact binaries

Posted by Chicago

Kavli Affiliate: Daniel E. Holz | First 5 Authors: Jose María Ezquiaga, Daniel E. Holz, , , | Summary: We explore the use of the mass spectrum of neutron stars and black holes in gravitational-wave compact binary sources as a cosmological probe. These standard siren sources provide direct measurements of luminosity distance. In addition, features […]

Incorporating galaxy cluster triaxiality in stacked cluster weak lensing analyses

Posted by dbos Stanford

Kavli Affiliate: Eli Rykoff | First 5 Authors: Zhuowen Zhang, Hao-Yi Wu, Yuanyuan Zhang, Joshua Frieman, Chun-Hao To | Summary: Counts of galaxy clusters offer a high-precision probe of cosmology, but control of systematic errors will determine the accuracy of this measurement. Using Buzzard simulations, we quantify one such systematic, the triaxiality distribution of clusters […]
