How Does Diffusion Influence Pretrained Language Models on Out-of-Distribution Data?

Kavli Affiliate: Jing Wang | First 5 Authors: Huazheng Wang, Daixuan Cheng, Haifeng Sun, Jingyu Wang, Qi Qi | Summary: Transformer-based pretrained language models (PLMs) have achieved great success in modern NLP. An important advantage of PLMs is good out-of-distribution (OOD) robustness. Recently, diffusion models have attracted a lot of work to apply diffusion to […]

Reinforcement Learning for Sequential Decoding of Generalized LDPC Codes

Kavli Affiliate: Salman Habib | First 5 Authors: Salman Habib, David G. M. Mitchell, , , | Summary: In this work, we propose reinforcement learning (RL) for sequential decoding of moderate length generalized low-density parity-check (GLDPC) codes. Here, sequential decoding refers to scheduling all the generalized constraint nodes (GCNs) and single parity-check nodes (SPCNs) of […]

Flat-sky Angular Power Spectra Revisited

Kavli Affiliate: Anthony Challinor | First 5 Authors: Zucheng Gao, Zvonimir Vlah, Anthony Challinor, , | Summary: We revisit the flat-sky approximation for evaluating the angular power spectra of projected random fields by retaining information about the correlations along the line of sight. With broad, overlapping radial window functions, these line-of-sight correlations are suppressed and […]

A Novel Computationally Efficient Group Signature for Anonymous and Secure V2X Communications

Kavli Affiliate: Jia Liu | First 5 Authors: Jia Liu, Liqun Chen, Mehrdad Dianati, Carsten Maple, Yan Yan | Summary: The use of vehicle-to-everything (V2X) communication is expected to significantly improve road safety and traffic management. We present an efficient protocol, called the AEE protocol, for protecting data authenticity and user privacy in V2X applications. […]

Non-Supersymmetric Heterotic Strings on a Circle

Kavli Affiliate: Savdeep Sethi | First 5 Authors: Bernardo Fraiman, Mariana Graña, Héctor Parra De Freitas, Savdeep Sethi, | Summary: Motivated by a recent construction of non-supersymmetric $text{AdS}_3$, we revisit the $O(16)times O(16)$ heterotic string compactified on a torus. The string one-loop potential energy has interesting dependence on the classical moduli; extrema of this potential […]

The impact of cosmic rays on the interstellar medium and galactic outflows of Milky Way analogues

Kavli Affiliate: Debora Sijacki | First 5 Authors: Francisco Rodríguez Montero, Sergio Martin-Alvarez, Adrianne Slyz, Julien Devriendt, Yohan Dubois | Summary: During the last decade, cosmological simulations have managed to reproduce realistic and morphologically diverse galaxies, spanning the Hubble sequence. Central to this success was a phenomenological calibration of the few included feedback processes, whilst […]
