Incremental ELMVIS for unsupervised learning
Anton Akusok, Emil Eirola, Yoan Miche +5
An incremental version of the ELMVIS+ method is proposed in this paper. It iteratively selects a few best fitting data samples from a large pool, and adds them to the model. The me…
Te-REX: a sample of extragalactic TeV-emitting candidates
B. Balmaverde, A. Caccianiga, R. Della Ceca +7
The REX (Radio-Emitting X-ray sources) is a catalogue produced by cross-matching X-ray data from the ROSAT-PSPC archive of pointed observations and radio data from the NRAO VLA Sky…
The GW compendium: A practical guide to theoretical photoemission spectroscopy
Dorothea Golze, Marc Dvorak, Patrick Rinke
The GW approximation in electronic structure theory has become a widespread tool for predicting electronic excitations in chemical compounds and materials. In the realm of theoreti…
The Solar Radius at 37 GHz through Cycles 22 to 24
Caius L. Selhorst, Juha Kallunki, C. G. Giménez de Castro +2
To better understand the influence of the activity cycle on the solar atmosphere, we report the time variation of the radius observed at 37 GHz (=8.1 mm) obtained by the Metsäho…
How much physics is in a current-voltage curve? Inferring defect properties from photovoltaic device measurements
Rachel C. Kurchin, Jeremy R. Poindexter, Ville Vähänissi +3
Defect-assisted recombination processes are critical to understand, as they frequently limit photovoltaic (PV) device performance. However, the physical parameters governing these…
HAL: Improved Text-Image Matching by Mitigating Visual Semantic Hubs
Fangyu Liu, Rongtian Ye, Xun Wang +1
The hubness problem widely exists in high-dimensional embedding space and is a fundamental source of error for cross-modal matching tasks. In this work, we study the emergence of h…
