Multitask Learning for Low Resource Spoken Language Understanding
Quentin Meeus, Marie-Francine Moens, Hugo Van hamme
We explore the benefits that multitask learning offer to speech processing as we train models on dual objectives with automatic speech recognition and intent classification or sent…
The VLT-FLAMES Tarantula Survey: Observational evidence for two distinct populations of massive runaway stars in 30 Doradus
H. Sana, O. H. Ramírez-Agudelo, V. Hénault-Brunet +17
Two main scenarios have been proposed for origin of massive runaway stars -- dynamical ejection or release from a binary at the first core collapse -- but their relative contributi…
First spatially resolved Na I and He I transitions towards an MYSO. Finding new tracers for the gaseous star/disc interface
Evgenia Koumpia, M. Koutoulaki, W. -J. de Wit +4
With steady observational advances, the formation of massive stars is being understood in more detail. Numerical models are converging on a scenario where accretion discs play a ke…
Generation of solar chromosphere heating and coronal outflows by two-fluid waves
M. Pelekhata, K. Murawski, S. Poedts
Context. It is known that Alfvén and magnetoacoustic waves both contribute to the heating of the solar chromosphere and drive plasma outflows. In both cases, the thermalization of…
Improving CME evolution and arrival predictions with AMR and grid stretching in Icarus
Tinatin Baratashvili, Christine Verbeke, Nicolas Wijsen +1
Coronal Mass Ejections (CMEs) are one of the main drivers of disturbances in the interplanetary space. Strong CMEs, when directed towards the Earth, cause geo-magnetic storms upon…
Radiative Transfer as a Bayesian Linear Regression problem
Frederik De Ceuster, Thomas Ceulemans, Jon Cockayne +2
Electromagnetic radiation plays a crucial role in various physical and chemical processes. Hence, almost all astrophysical simulations require some form of radiative transfer model…
