SEAS: Self-Evolving Adversarial Safety Optimization for Large Language Models

Autor: Diao, Muxi, Li, Rumei, Liu, Shiyang, Liao, Guogang, Wang, Jingang, Cai, Xunliang, Xu, Weiran

As large language models (LLMs) continue to advance in capability and influence, ensuring their security and preventing harmful outputs has become crucial. A promising approach to address these concerns involves training models to automatically gener

Report

A microwave photonic prototype for concurrent radar detection and spectrum sensing over an 8 to 40 GHz bandwidth

Autor: Shi, Taixia, Liang, Dingding, Wang, Lu, Li, Lin, Guo, Shaogang, Gao, Jiawei, Li, Xiaowei, Lin, Chulun, Shi, Lei, Ding, Baogang, Liu, Shiyang, Yang, Fangyi, Jiang, Chi, Chen, Yang

In this work, a microwave photonic prototype for concurrent radar detection and spectrum sensing is proposed, designed, built, and investigated. A direct digital synthesizer and an analog electronic circuit are integrated to generate an intermediate

Reducing the impact of non-ideal PRBS on microwave photonic random demodulators by low biasing the optical modulator via PRBS amplitude compression

Autor: Liu, Shiyang, Chen, Yang

A novel method for reducing the impact of non-ideal pseudo-random binary sequence (PRBS) on microwave photonic random demodulators (RDs) in a photonics-assisted compressed sensing (CS) system is proposed. Different from the commonly used method that
