So far the data was not normalized... is that the reason the predictions are not that good?

nmheim commented 5 years ago

In addition to normalizing the data, adding a bias vector to the ESNCell improves prediction a lot (commit 9830b5cccf0c19eeed24ef340694b9c8ec917176). Still have to run over the whole dataset to produce some concrete numbers.

Check what the internal TanhRNNCell of pytorch does. There is a possible second bias term for the reservoir layer, which could mean that the input and reservoir layers have two seperate activation functions...

@jamesavery prediction performance should be fixed with 181dc9b0cbcb0ff0b08153716b04baef2590a4a1
