In this paper , we extend traditional linear FKT to enable it to work in multi-class problem and also in higher dimensional -LRB- kernel -RRB- subspaces and therefore provide enhanced discrimination ability .
 used for: linear FKT, it; used for: it, multi-class problem; used for: it, higher dimensional -LRB- kernel -RRB- subspaces; feature of: it, discrimination ability; conjunction: multi-class problem, higher dimensional -LRB- kernel -RRB- subspaces
Given options, please tell me the relationships of all the listed entity pairs.Output format is "relation1: word1, word2; relation2: word3, word4". 
Option: conjunction, feature of, hyponym of, used for, part of, compare, evaluate for
