Hi,
I am trying to classify a set of ECG Data in two classes using CNN.
Iam having input of 40 records as 40x15000 and output as 40x1 categorical.
% layers defined as the CNN architecture model and % option as training option(sgdm)
Indices = crossvalind('Kfold',output , 10);
cp = classperf(output);
for i=1:10
test = (Indices == i);
train = ~test;
net = trainNetwork(input(train,:),output(train,:),layers,options);
class = classify(net,input(test,:));
classperf(cp,class, test);
end
cp.CountingMatrix();
for trainNetwork output must be categorical.
Error using classperf (line 206)
Ground truth must be a cell array of character vectors or a numeric array.
how to solve this error
I am using matlab2018a
please help!!
Thanks
