Beyond the Matrix Sign: Quadratic Spectral Descent

Qiaozhe Zhang, Jun Sun, Yingzhuang Liu

Muon emerges as a strong competitor of the AdamW for LLM pretraining, because the matrix-wise update it employs can potentially incur smaller second-order penalty than the once dom…

Rényi Sharpness: A Novel Sharpness that Strongly Correlates with Generalization

Qiaozhe Zhang, Jun Sun, Ruijie Zhang +1

Sharpness (of the loss minima) is widely believed to be a good indicator of generalization of neural networks. Unfortunately, the correlation between existing sharpness measures an…

Analog Self-Interference Cancellation in Full-Duplex Radios: A Fundamental Limit Perspective

Limin Liao, Jun Sun, Junzhi Wang +1

Analog self-interference cancellation (A-SIC) plays a crucial role in the implementation of in-band full-duplex (IBFD) radios, due to the fact that the inherent transmit (Tx) noise…

Achieving Interference-Free Degrees of Freedom in Cellular Networks via RIS

Junzhi Wang, Jun Sun, Zheng Xiao +2

It's widely perceived that Reconfigurable Intelligent Surfaces (RIS) cannot increase Degrees of Freedom (DoF) due to their relay nature. A notable exception is Jiang \& Yu's work.…
