Training data and Training target in Neural Networks
15 views (last 30 days)
I am having a signal in form of vector (1*25000). I want to split this signal into four parts x_train, y_train, x_test and y_test (according to 70-30% training and testing method) in MATLAB. Can anyone help me how to split this vector form signal into these four parts?

You cannot make any intelligent decisions until you have examined a plot of the data!!!
(WRONG!!! Plotting the data first is the ultimate beginning decision!!!)
Hope this helps.

You have correctly divided the data using randperm. Since you didn’t have ground truth, you are taking last 8750 as ground truth as per following code:
mat_1 = reshape(train_data, [rownr_1, colnr_1]);
x_train = mat_1(:,1);
y_train = mat_1(:,2);
which is incorrect. Select the correct ground truth.
