code:
input = [0 0 1;
0 1 1;
1 0 1;
1 1 1;
];
correct_Output = [0 0.5;
0 0.9;
1 1.2;
1 1.3;
];
Weight = 2*rand(1,3) - 1;
for epoch = 1:10000
Weight = SGD_method(Weight,input,correct_Output);
end
save('Trained_Network.mat')
%function
function Weight = SGD_method(Weight,input, correct_Output)
alpha = 0.9;
N = 4;
for k = 1:N
transposed_Input = input(k,:)';
d = correct_Output(k);
weighted_Sum = Weight*transposed_Input;
output = Sigmoid(weighted_Sum);
error = d-output;
delta = output*(1-output)*error;
dWeight = alpha*delta*transposed_Input;
Weight(1) = Weight(1) + dWeight(1);
Weight(2) = Weight(2) + dWeight(2);
Weight(3) = Weight(3) + dWeight(3);
end
end
%function
function y = Sigmoid(x)
y = 1/(1+exp(-x));
end
the above code excutes if
correct_Output = [0
0
1
1
]
but i want to execute the above code such that the
correct_Output = [0 0.5;
0 0.9;
1 1.2;
1 1.3;
];
Could anyone please help me on this.
