Hi everyone.

I trained LSTM network for price prediction.I have info.TrainingRMSE of LSTM. But I want to get final value of RMSE for training to compare between training RMSE and testing RMSE.

How can I calculate final value of training RMSE? Please help me.Thanks.

And I have another question. Why some values of ValidationRMSE is NaN?

Hi Nazila,

You can access the final Training and Validation RMSE from the info struct returned by trainNetwork, by accessing the last element:

>> info.TrainingRMSE(end)

Some values of the vector info.ValidationRMSE are NaN since they correspond to the iterations where the model is not evaluated on the validation dataset. You can set how often the model is evaluated on the validation dataset with the ValidationFrequency training option.
