Hierarchy generation for numerical data

WebAbstract. Organisms are non-equilibrium, stationary systems self-organized via spontaneous symmetry breaking and undergoing metabolic cycles with broken detailed balance in the environment. The thermodynamic free-energy (FE) principle describes an organism’s homeostasis as the regulation of biochemical work constrained by the physical FE cost. WebA concept hierarchy is a kind of concise and general form of concept description that organizes relationships of data and expresses knowledge as a tree-like or partial ordering structure. In this paper, we propose an approach to generate concept hierarchies automatically for a given data set with nominal attributes based on rough entropy.
