Is this LSTM model underfitting?

Question

I think this model is underfitting. Is this correct?

_________________________________________________________________
Layer (type)                 Output Shape              Param #   
=================================================================
lstm_1 (LSTM)                (50, 60, 100)             42400

_________________________________________________________________
dropout_2 (Dropout)          (50, 60)                  0

dense_1 (Dense)              (50, 20)                  1220

dense_2 (Dense)              (50, 1)                   21        
=================================================================

The above is a summary of the model.
Any advice on how the model could be improved?

Answer 1

You need to include optimizer you used to make sure it is correct. By the way, your drop-out layers are not going to do anything, so you should take them away.

You likely don’t have test and train data in time-series because all data points are connected. It just has prediction value and ground truth of each period.

I recommend you use the whole dataset and rotate changing hyper-parameters of LSTM to find the best model.
