Rough Sets, Pareto Optimality, and Swarm Algorithms Explained

24(a) Meaning of Indiscernibility

  • Two objects are indiscernible if they have same values for a chosen set of attributes.

  • Forms equivalence classes (granules).

  • Basis for lower/upper approximations in Rough Sets.


24(b) Reduct & Core

Reduct

  • Minimum subset of attributes giving same classification power as full set.

  • Removing any attribute → information loss.

Core

  • Intersection of all reducts


  • Contains attributes must for classification.

Example (Medical dataset)


  • Attributes: Headache, Muscle Pain, Temperature
