Hello all,
I wonder is it necessary or correct to do z score transformation before PCA? I

I did some more tests. My issue that I brought up may be related to the

I have an SVR model that uses custom kernel as follows:
1)
sgk = dual_laplace_gaussian_swarm(ss)
svr_cust_sig = SVR(kernel=sgk, C=C_Value, epsilon = epsilon_value)
svr_fit = svr_cust_sig.fit(X, y)
#X is an array shape is [93, 24] where each row is a time in the columns are
variables for the mode
