Spatio-temporal Reasoning for Vague Regions
Abstract. This paper extends a mereotopological theory of spatiotemporal reasoning to vague ”egg-yolk” regions. In this extension, the egg and its yolk are allowed to move and ...

Rough Sets and Higher Order Vagueness
Abstract. We present a rough set approach to vague concept approximation within the adaptive learning framework. In particular, the role of extensions of approximation spaces in se...
