I'm currently trying to build a simple model for predicting time series. The goal would be to train the model with a sequence so that the model is able to predict future values.
I'm using tensorflow and lstm cells to do so. The model is trained with truncated backpropagation through time. My question is how to structure the data for training.
For example let's assume we want to learn the given sequence:
[1,2,3,4,5,6,7,8,9,10,11,...]
And we unroll the network for num_steps=4.
Option 1
input data label
1,2,3,4 2,3,4,5
5,6,7,8 6,7,8,9
9,10,11,12 10,11,12,13
...
Option 2
input data label
1,2,3,4 2,3,4,5
2,3,4,5 3,4,5,6
3,4,5,6 4,5,6,7
...
Option 3
input data label
1,2,3,4 5
2,3,4,5 6
3,4,5,6 7
...
Option 4
input data label
1,2,3,4 5
5,6,7,8 9
9,10,11,12 13
...
Any help would be appreciated.
