Dimensions of my inputs are as follows: X_train_reshape = np.reshape( Dealing with a Multivariate Time Series - VAR. As you can see here, the formula to standardize is: This means that x' should be the mean of all the lists in a column (for example F1), and S should be the stdev of all the lists in a column. Or phrased differently, our problem is essentially the problem of classifying multivariate time series. Suspicious php links found on cPanel visitors, Predicting using ML model on training set. Also, if the change in scale is small, but the model breaks down it means that the model is not robust to small disturbances, a problem in and of itself, in my opinion. A possible reason could be that, although PCMCI has been proposed to analyze large-scale multivariate time series, during the two-stage process of the algorithm, if any of the PC-stage or MCI-stage fault, the results may be changed, which may be more evident for short time series with a large number of variables. So, if it's constant then your scale shouldn't change if you calculated it on subsamples.
