Old code with now reduced norms of 2 and increased sampling of 7. Bug is where train and test are separately normalized, which can lead to biases and jumps. This is addressed in the 927*lstm_time code, where it tries to first construct normalized series and then split the data in order to avoid jumps. Issue is still with the time split component, that does not work. Therefore this code is a test reference if the other 927_time code does not work.
