摘要粒计算的形式化研究一直没有被仔细讨论. 文中在集合论框架下, 对粒计算做了系统研究,
给出了粒度空间的三层模型(论域, 基, 粒结构). 借用逻辑语言L 判定粒的可定义性 …

Granule description is a fundamental problem in granular computing. Although the spirit of
granular computing has been widely adopted in scientific researches, how to classify and …

In this paper, we discuss a semantically sound approach to covering-based rough sets. We
recall and elaborate on a conceptual approach to Pawlak's rough set model, in which we …

Granule description is one of the main challenges to realize explainable AI technologies
through information granules. Specifically, granule description of incomplete data is still an …

A framework is proposed for studying a particular class of set-theoretic approaches to
granular computing. A granule is a subset of a universal set, a granular structure is a family …

Granule description is a fundamental problem in granular computing. The existing studies
are mainly based on Wille's concept lattice, and attribute reduction techniques, eg, minimal …

The problem of concept formation and learning is examined from the viewpoint of granular
computing. Correspondences are drawn between granules and concepts, between …

Knowledge plays a central role in human and artificial intelligence. One of the key
characteristics of knowledge is its structured organization. Knowledge can be and should be …

Granular computing is an emerging field of study that attempts to formalize and explore
methods and heuristics of human problem solving with multiple levels of granularity and …

Multilevel granular structures play a fundamental role in granular computing. In this chapter,
we present a general framework of granular spaces. Within the framework, we examine the …
