Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：全同态加密方案及其应用研究进展
全同态 加密方案 应用研究
2023/4/13
该报告首先介绍格密码安全性分析中带来的数学问题和基于符号推导自动产生可读的分析过程。在此基础上我们初步研究了格密码方案中的参数优化问题。其次，在应用方面设计了面向基因数据的同态计算方案，将其应用于膀胱癌诊断回归模型，以及前列腺癌的神经网络模型。由于理想格上的同态计算大多归结为高次大整数的多项式乘法，我们实现了FPGA硬件上的多项式乘法加速，为将来软硬件结合的大规模隐私计算方案设计奠定了基础。

Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：基于自监督表征学习的图像聚类算法研究
自监督表征学习 图像聚类算法 语义伪标签
2023/4/17
自监督学习可以为图像聚类算法提供良好的表征，但是当表征和聚类同步学习时会存在一些问题。具体来说，基于对比的自监督学习方法通常需要大量的负样本来使得所有样本的表征分离，但是负样本会带来类别冲突，进而影响下游的聚类性能；反之，基于非对比的自监督学习方法虽然避免了类别冲突问题，但是由于缺少负样本，与聚类任务联合优化时容易造成聚类崩溃。本报告将围绕这两个问题，分别介绍基于语义伪标签和原型对比的图像聚类算法...
