I'm curently studing the topic of Possibilistic shell clustering and I have a hard time with understanding the concept of variable $\eta$. Can somebody in simpe words explain me what exectly this variable is responsible for. The objective function which uses $\eta$ looks like that $$ J = \sum_{j=1}^{C}\sum_{i=1}^{N}u_{ij}^md_{ij}^2 + \sum_{j=1}^{C}\eta_{j}\sum_{i=1}^{N}(1-u_{ij})^m $$
