Hi @marijnhazelbag,
For the moment we are only estimating quantiles using the quantile regression like in the paper and main M4 competition.
We have implemented a multi-quantile loss function here:
https://github.com/Nixtla/nixtlats/blob/master/nixtlats/losses/pytorch.py#L317
I imagine, it could be easy to adapt the final layer of the ES-RNN to output multi-quantiles.
https://github.com/kdgutier/esrnn_torch/blob/master/ESRNN/utils/ESRNN.py#L285
Let me know if you want to try it, or would you need help with it.

Thank you for the swift response! I will try and let you know if I run into problems :)

I am reaching a friend who might have already done it to point you to his work.

Hi, @marijnhazelbag,
Thanks for your interest. We have written the multi-quantile version of the ESRNN model: MQESRNN; you can find it in our new library for time series forecasting using Deep Learning named nixtlats, in particular here. You can import it using:
from nixtlats.models.esrnn.mqesrnn import MQESRNN
You pass a list of percentiles to obtain prediction intervals; for example, if you want a 90% prediction interval, you could use training_percentiles=[5, 50, 95]
. Under the hood, the model trains the ESRNN model using the multiquantile loss.

Thank you, gentlemen! I really appreciate it.
