问题同样为聚类小联系一种问题
问题原述:将文件1.mat中数据分为两类;
算法介绍见文献:Gan G, Wu J. A convergence theorem for the fuzzy subspace clustering (FSC) algorithm. Pattern Recognition, 2008,41(6):
clear; clc; load 1.mat; jig=data'; z=[jig(1,:) jig(2,:)]; w=ones([2,100])./100; alp=2; lmd=0.5; err=0.01; dd=ones([1,2]); errma=1; E=0; n=1; while errma>err; n=n+1; if n==1000000; break; end u=zeros([2,200]); for i=1:200; for j=1:2; dd(1,j)=w(j,:).^alp*((jig(i,:)-z(j,:)).^2)'; if j==2 && dd(1,j)>dd(1,1); u(1,i)=1; end if j==2 && dd(1,j)<=dd(1,1); u(2,i)=1; end end end adds=0; for j=1:2; for i=1:200; adds=adds+u(j,i)*w(j,:).^alp*((jig(i,:)-z(j,:)).^2)'; end end EE=lmd*sum(sum(w.^alp))+adds; errma=abs(EE-E); E=EE; for j=1:2; for h=1:100; sum1=0; for t=1:100; sum2=0; sum3=0; for i=1:200; sum2=sum2+u(j,i)*(jig(i,j)-z(j,h))^2; sum3=sum3+u(j,i)*(jig(i,t)-z(j,t))^2; end sum1=sum1+((sum2+lmd)/(sum3+lmd))^(1/(alp-1)); end w(j,h)=1/sum1; end end for j=1:2; for h=1:100; z(j,h)=u(j,:)*jig(:,h)/sum(u(j,:)); end end end
