Non-Monotonic Attention-based Read/Write Policy Learning for Simultaneous Translation

Posted by klaurent March 28, 2025March 31, 2025Stanford, This Week: Astrophysics

Kavli Affiliate: Zeeshan Ahmed | First 5 Authors: Zeeshan Ahmed, Frank Seide, Zhe Liu, Rastislav Rabatin, Jachym Kolar | Summary: Simultaneous or streaming machine translation generates translation while reading the input stream. These systems face a quality/latency trade-off, aiming to achieve high translation quality similar to non-streaming models with minimal latency. We propose an approach […]

Proposal for a shared transverse LLP detector for FCC-ee and FCC-hh and a forward LLP detector for FCC-hh

Posted by klaurent March 27, 2025March 31, 2025This Week: Astrophysics, Tokyo

Kavli Affiliate: Shigeki Matsumoto | First 5 Authors: Biplob Bhattacherjee, Camellia Bose, Herbi K. Dreiner, Nivedita Ghosh, Shigeki Matsumoto | Summary: As the particle physics community has explored most of the conventional avenues for new physics, the more elusive areas are becoming increasingly appealing. One such potential region, where new physics might be hiding, involves […]

Wave Interference in Self-Interacting Fuzzy Dark Matter

Posted by klaurent March 27, 2025March 31, 2025Chicago, This Week: Astrophysics

Kavli Affiliate: Wayne Hu | First 5 Authors: Christian Capanelli, Wayne Hu, Evan McDonough, , | Summary: In the Fuzzy Dark Matter (FDM) scenario, the dark matter is composed of an ultra-light scalar field with coherence length and wave interference on astrophysical scales. Scalar fields generically have quartic self-interactions that modify their dispersion relation and […]
