主讲人简介：
Davide Ciucci received a PhD in 2004 in computer science from the University of Milan and the Habilitation (HdR) from the University of Toulouse III in 2013. He is currently associate professor at the University of Milano-Bicocca. His research activity is about uncertainty representation and management, with particular reference to rough sets and non-classical logics, on which he published more than 90 papers. He is president of the International Rough Set Society, Senior Area Editor of Int. J. of Approximate Reasoning and Associate Editor of Array.
讲座介绍：
We will introduce the notion of orthopair as a set with uncertain boundaries and we will discuss its relationship to some knowledge representation tools including three-valued logics and rough sets. A collection of orthopairs will then be used to define an orthopartition as a generalized partition with uncertainty. Finally, uncertainty measures will be introduced on orthopairs and orthopartitions and their applicability to Machine Learning will be investigated, in particular to evaluate soft clustering algorithms and to address data ambiguity with the proposal of some three-way-in and three-way-our learning algorithms.
