Superposition- and interference-induced optical spectrum distortion in the figure-9 fiber laser

Kavli Affiliate: Xiang Zhang | First 5 Authors: Xiang Zhang, Guochao Wang, Kangrui Chang, Haobin Zheng, Yongzhuang Zhou | Summary: The spectrum of the output pulses from the figure-9 laser typically exhibits more distortion than the spectra from mode-locked lasers based on other saturable absorbers and the spectrum of its intracavity pulses. Here, we demonstrate […]

Counting Ability of Large Language Models and Impact of Tokenization

Kavli Affiliate: Xiang Zhang | First 5 Authors: Xiang Zhang, Juntai Cao, Chenyu You, , | Summary: Transformers, the backbone of modern large language models (LLMs), face inherent architectural limitations that impede their reasoning capabilities. Unlike recurrent networks, Transformers lack recurrent connections, confining them to constant-depth computation. This restriction places them in the complexity class […]
