A Feature Weighted Fuzzy Clustering Algorithm Based on Multistrategy Grey Wolf Optimization
Algorithm 3
MSGWO-WFCM.
Input: dataset X = {x1,…,xN}, number of clusters K, parameters m and t, number of population n, initial value ainitial and terminal value afinal of the convergence factor, threshold parameter ξ, maximum iterations tmax, and fitness value ft(Vt) of t generation population
Output: clustering result vector q
(1)
Use the strategy of population diversity to initialize n populations. The centroid matrix of the ith population is Vi (i = 1,…,n);
(2)
Initialize the weight matrix Wi corresponding to the i-th particle;
