Analyzing of optimal classifier selection for EEG signals of depression patients based on intelligent fuzzy decision support systems

In this section, we generalized the aggregation operators of LDFSs by using the concept of extended copulas and copula. First, we proposed extended copulas and generators of extended copulas for LDFSs.

Operational laws of LDFSs using extended copulas

This section provides a detailed description of the operational laws of extended copulas³² and their generators and also discuss their fundamental properties. These operations shall be used in the development of AOs of LDFSs.
