Testing multivariate LSTM and multivariate ARIMA on synthetic time series. The approach works. Next step would be with real PISCES data set. It is still unclear how to weights for linear lag correlation model should be applied. Using just multivariate ARIMA and LSTM or lagged multivariate, where the maximum cross correlation should be the constrain on time lagged external factors?
