Hello,

Currently, COCA accepts datasets that are univariate. Is it possible to expand to multivariate?

Thanks, Marcia

Sorry, the original COCA does not perform well on multivariate time series. We guess that this may be because the model is not complex enough. You can try deepening the network layers and replacing LSTM with the Transformer.
