2018年10月16日上午，应赵才荣副研究员、苗夺谦教授的邀请，加拿大里贾纳大学姚一豫教授来电信学院作学术报告，暨第130期智信讲坛，并与师生在C310室进行了学术交流。

学院师生对姚一豫教授的到来表示热烈欢迎，讲座会场座无虚席。苗夺谦教授首先向大家介绍了姚老师的成就，姚教授表示很荣幸在同济大学举办此次报告。姚教授作了题为“The Art and Science of Three-Way Decisions”的学术报告。他指出，粒计算（Granular Computing）是基于信息粒的问题求解与数据分析理论方法，粒计算以信息粒为基本计算单位，以处理数据不确定性、建立大规模复杂数据的有效分析模型为研究目标，已成为数据挖掘与知识发现领域的一类重要计算范式。三支决策是粒计算理论的新方向，已经在诸多机器学习应用问题中体现出巨大的发展潜力。报告将简要回顾三支决策的起源，发展，并深入分析三支决策理论的学术贡献。 他的近期研究“三支决策的分、治、效”思想已经将三支决策理论与哲学思想深入结合，奠定了三支决策理论的哲学基础。

姚教授的报告学术积淀深厚，对在场师生的学习和研究产生巨大的影响。报告结束后，姚教授对在场师生提出的问题均做了精准详细解答，大家都受益匪浅。
