我系于2017年11月03日上午10:00在智园A7栋1113会议室，举办了“MDS Codes for Distributed Storage system”和“Progress and Development Trend of Cache Assisted Wireless Communication Technology”两场专题讲座，西南交通大学唐小虎教授及陈庆春教授为此次讲座主讲人。

在此次讲座中，唐小虎教授跟大家分享的是在分布式存储系统当中MDS编码技术，针对现今的大数据时代，通过MDS编码来提高数据存储的效率和减少存储的冗余，唐教授给出了巧妙的理论推导和形象的数学模型来解释MDS编码方式。陈庆春教授首先就编码方式、理论框架和应用等几个方面为大家介绍了缓存辅助无线通信技术，重点阐述了缓存辅助的协作多中继的网络和缓存辅助无限能量收获中继网络的应用，最后针对高速缓存辅助无线通信技术的发展现状，陈教授和大家一起畅谈了该技术在计算-存储-协同通信和人工智能方向上的广阔前景。

讲座结束后，现场前来听取的同学提出了有关讲座内容的问题，两位教授一一作出解答。
