UnitNorm: Rethinking Normalization for Transformers in Time Series

Kavli Affiliate: Xiang Zhang | First 5 Authors: Nan Huang, Christian Kümmerle, Xiang Zhang, , | Summary: Normalization techniques are crucial for enhancing Transformer models’ performance and stability in time series analysis tasks, yet traditional methods like batch and layer normalization often lead to issues such as token shift, attention shift, and sparse attention. We […]

The density-bounded twilight of starbursts in the early Universe

Kavli Affiliate: Roberto Maiolino | First 5 Authors: William McClymont, Sandro Tacchella, Francesco D’Eugenio, Callum Witten, Xihan Ji | Summary: The peculiar nebular emission displayed by galaxies in the early Universe presents a unique opportunity to gain insight into the regulation of star formation in extreme environments. We investigate 500 (109) galaxies with deep NIRSpec/PRISM […]

Complementarity for a Dynamical Black Hole

Kavli Affiliate: Yasunori Nomura | First 5 Authors: Benjamin Concepcion, Yasunori Nomura, Kyle Ritchie, Samuel Weiss, | Summary: Black hole complementarity posits that the interior of a black hole is not independent from its Hawking radiation. This leads to an apparent violation of causality: the interior can be acausally affected by operators acting solely on […]

Faraday tomography with CHIME: the `tadpole’ feature G137+7

Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: Nasser Mohammed, Anna Ordog, Rebecca A. Booth, Andrea Bracco, Jo-Anne C. Brown | Summary: A direct consequence of Faraday rotation is that the polarized radio sky does not resemble the total intensity sky at long wavelengths. We analyze G137+7, which is undetectable in total intensity but […]

$nπ$ phase ambiguity of cosmic birefringence

Kavli Affiliate: Toshiya Namikawa | First 5 Authors: Fumihiro Naokawa, Toshiya Namikawa, Kai Murai, Ippei Obata, Kohei Kamada | Summary: We point out that the rotation angle $beta$ of cosmic birefringence, which is a recently reported parity-violating signal in the cosmic microwave background (CMB), has a phase ambiguity of $npi ,(ninmathbb{Z})$. This ambiguity has a […]
