基于模拟的经验贝叶斯

Xinwei Shen, Diana Cai, Cheng Zhang, David M. Blei

机构 * Department of Statistics University of Washington(统计学系华盛顿大学) Department of Computer Science Cornell University(计算机科学系康奈尔大学) School of Mathematical Sciences and Center for Statistical Science Peking University(数学科学学院与统计科学中心北京大学) Departments of Computer Science and Statistics Columbia University(计算机科学与统计学系哥伦比亚大学)

AI总结 研究针对似然只能通过模拟器获得的情况开发经验贝叶斯方法,引入基于模拟的经验贝叶斯(SBEB),通过观测数据、模拟器样本和推断网络计算估计,迭代细化先验,经实验证明其比固定先验的SBI提高了准确性。

Adversarial Prompts for Acceptance Collapse in Speculative Decoding

推测解码中用于接受崩溃的对抗性提示

Run Wang, Chaoyi Zhou, Xi Liu, Yi Zhu, Amir Salarpour, Pedram MohajerAnsari, Zhi-Qi Cheng, Feng Luo, Siyu Huang, Mert D. Pesé

机构 * Clemson University(克莱姆森大学) Wayne State University(韦恩州立大学) University of Washington(华盛顿大学)

AI总结 研究针对推测解码中草稿-目标对齐漏洞的攻击,提出ADSD方法,利用Soft-Collapse及目标保留目标生成对抗性后缀,在GSM8K数据集上验证其有效性,还证明该漏洞存在于多方面。
