Iam working with EMG signals .I found features of three signals and I need to use classfication learner app.When I use the same set of features the accuracy is varying for same validation (like cross validation and Hold out validation) with PCA.Why it is like that?
How can I get the accuracy same for all the time

Before every run, use rng() to set the random number seed to a consistent value.
Most training systems for classifiers and neural networks use random numbers.

for K = 1 : 5
rng(12345)
run the classification at this point
%you should get consistent answers
end
