"If you want to use the model in my code (the link you passed), you need to have the data correctly shaped: (1 sequence, total_time_steps, 5 features) Important: I don't know if this is the best way or the best model to do this, but this model is predicting 7 time steps ahead of the input ( time_shift=7) Data and initial vars See more Your model wasn't very powerful for this task, so I tried a bigger one (this on the other hand is too powerful) See more Notice that I had to train 2000+ epochs for the model to have good results. I added the validation data so we can compare the loss for train and test. See more Please notice that this model is overfitting, it means it can learn the training data and get bad results in test data. To solve this you must experimentally try smaller models, use dropout … See more Important: as for predicting the end of a sequence based on the beginning, it's important that the model sees the beginning to adjust the internal states, so I'm predicting the entire data (x_predict), not only the test data.
