我想申請感知算法fisheriris數據和我嘗試這種代碼fisheriris數據和感知
function [ ] = Per()
%PERCEPTON_NN Summary of this function goes here
% Detailed explanation goes here
%%%%%%%%%%%STEP ONE INPUT DATA PREPERATION
%N=3000;
load fisheriris
tr=50; %traning
te=50; %test
epochs =150;
data=meas;
%N = size(meas,1);
%species=nonomil(species)
%figure,plot(data_shuffeled(1,:),data_shuffeled(2,:),'rx');
%%%%%%%%%%%%%%%%%%%STEP TWO INTIALIZE WEIGHT
baise=1;
w=[baise; 1 ; 1;1 ; 1];
eta=0.9; %%learning rate
%%%%%%%%%%%%%%%%%%%%%%%% Rosen Blatt learning Algo
for epoch=1 : epochs
for i=1 : tr
x=[1;data(i,1);data(i,2);data(i,3);data(i,4)]; % input vector
N = size(species,i); %desiard output
y=w'*x; % y=actual output ,w'= transpose w , mmoken y=w.*x
%%%%%%%%%%%%%%% Activation function (hardlimit)(step fn)
y=1*(y>=0)+(-1)*(y<0); % da badl el if
%%%%%%%%%%% Error calcualtion %%%%%%%
err(i)=N-y;
%%%%%%%%%%%%%% update weight %%%%%%%%%5
wnew=w+ eta*err(i)*x;
w=wnew;
end
mse(epoch)=mean(err.^2);
end
%%%%%%%%%%%%%%%%%%%%%% step four classification (testing) %%%%%%%%%%%%%%%%%%5
hold on
for i=1 : te
%x=[1;data(i,1);data(i,2),data(i,3);data(i,4)];
x=[1;data(i,1);data(i,2);data(i,3);data(i,4)];
% d=data_shuffeled(3,i+tr);
N = size(species,i);
y=w'*x;
y=1*(y>=0)+(-1)*(y<0);
if (y==1)
plot(x(2),x(3),x(4),x(5),'rx');
elseif y==-1
plot(x(2),x(3),x(4),x(5),'r&');
end
end
hold off
if abs(N-y)>1E-6
testerro=testerro+1;
end
我寫了這個代碼,以使與fisheriris數據「MEAS」感知算法作爲輸入和物種「輸出」
對代碼的任何幫助或對此代碼的任何修改。
謝謝。
這個問題太籠統了。將來,請提供可管理的小代碼片段,指出您正面臨的特定問題,然後準確指出您要查找的內容 - 性能改進,獲取的錯誤等等。 – kitchenette
