Not enough input arguments
显示 更早的评论
Why is it said not enough input arguments at momentum1 = zeros(size(W1)); ?
function [W1, W5, Wo] = MnistConv(W1, W5, Wo, X, D)
alpha = 0.01;
beta = 0.95;
momentum1 = zeros(size(W1));
momentum5 = zeros(size(W5));
momentumo = zeros(size(Wo));
N = length(D);
bsize = 100;
blist = 1:bsize:(N-bsize+1);
for batch = 1:length(blist)
dW1 = zeros(size(W1));
dW5 = zeros(size(W5));
dWo = zeros(size(Wo));
begin = blist(batch);
for k = begin:begin+bsize-1
x = X(:, :, k);
y1 = Conv(x, W1);
y2 = ReLU(y1);
y3 = Pool(y2);
y4 = reshape(y3, [],1);
v5 = W5*y4;
y5 = ReLU(v5);
v = Wo*y5;
y = Softmax(v);
d = zeros(10, 1);
d(sub2ind(size(d), D(k), 1)) = 1;
e = d - y;
delta = e;
e5 = Wo' * delta;
delta5= (y5 > 0).* e5;
e4 = W5' * delta5;
e3 = reshape(e4, size(y3));
e2 = zeros(size(y2));
W3 = ones(size(y2)) / (2*2);
for c = 1:20
e2(:, :,c) = kron(e3(:, :, c), ones([2 2])) .*W3(:, :, c);
end
delta2 = (y2 > 0) .* e2;
delta1_x = zeros(size(W1));
for c = 1:20
delta1_x(:, :,c) = conv2(x(:, :), rot90(delta2(:, :,c), 2), 'valid');
end
dW1 = dW1 + delta1_x;
dW5 = dW5 + delta5*y4';
dWo = dWo + delta*y5';
end
dW1 = dW1 / bsize;
dW5 = dW5 / bsize;
dWo = dWo / bsize;
momentum1 = alpha*dW1 + beta*momentum1;
W1 = W1 + momentum1;
momentum5 = alpha*dW5 + beta*momentum5;
W5 = W5 + momentum5;
momentumo = alpha*dWo + beta*momentumo;
Wo = Wo + momentumo;
end
end

"Why is it said not enough input arguments at momentum1 = zeros(size(W1)); ?"
Because you called the function without any input arguments (probably by clicking the big greeen "Run" button).
You need to call your function (e.g. from the MATLAB command line) with five input arguments, e,g.:
W1 = 1;
W5 = 2;
Wo = 3;
X = 4;
D = 5;
[W1, W5, Wo] = MnistConv(W1, W5, Wo, X, D)
Of course you will need to define appropriate arrays and values to suit whatever task you are doing, not just copy 1, 2, 3, etc. from my answer. And in future ignore that big green button.

it's not test code. run test MnistConvcode then run Matlab.
