LSTM in Deeplearning errors

Hello, Rapidminer community!
I recently started using Rapidminer and drawing inspiration from an LSTM network from Kaggle I have set out to try and make my own. Whenever I run the model it throws me the error "java.lang.IllegalArgumentException: J: Index [0] must not be >= shape[0]=1." at the apply model process.
The second problem I have (which might be the root to the evil) is the fact that my model keeps saying "Couldn't update network in epoch 1", "Couldn't update network in epoch n". This shows up in the logs view of the process. I have tried adjusting the biases and weights but I haven't been able to remove the said error.
Any help would be greatly appreciated.

    With LSTM, you need to use the TimeSeries to Tensor operator. I suggest that you look at the Airline passenger with regression LSTM example. It is a bit more involved to setup. Also, I wouldn't split your data like that. You will get quite different results depending on your split points. Take a look at sliding windows.

    Thank you for the help, however I after modelling my model after the airline passenger example I get a problem in the select process. "Process failed: Collection size is 0, requested element index is 1.".

    Everything is made as in the in the sample however it still throws that error :/
    It also gives the following output when training which is concerning (and possible root to the select process problem): "Epoch: 1, training score: NaN, testing score: NaN"

    @hughesfleming68 any input on my comment? Not to be rude or anything, but its been a few days. I appreciate the help
  • hughesfleming68hughesfleming68 Member Posts: 313   Unicorn
    @Repletion. I will check your process when I get to the office. Keep in mind that many people provide support to other users on a voluntary basis. We can't always be available. If you are going to post a process that you would like help with, please post some data. It is very hard to debug without it.
  • RepletionRepletion Member Posts: 24 Contributor I
    @hughesfleming68 yea I have alot of respect for you and the others who are helping here on the forums. Regarding the data, I forgot to post it in the comment I made. I have attached the csv file in this comment now.

    Got it. I will take a look.

    Not this one!
  • RepletionRepletion Member Posts: 24 Contributor I
    @hughesfleming68 thank you so much! You are god sent. 2 questions though (theoritical)
    What is the optimal amount of tensors to use? 1 tensor for every variable?
    What is most effective to use in a deep learning model, minibatches, or no minibatches? If no, then when is it a good idea to use minibatches?

    Again thank you for the help, much appriciated!

    @hughesfleming68 I see that part of the solution was changing the activation function of the LSTM layer to sigmoid instead of Relu, why cant I use Relu? It just throws the Nan epochs. I want to use Relu since its "superior" to the other activation functions.
  • hughesfleming68hughesfleming68 Member Posts: 313   Unicorn
    Yes, I noticed that too. Before you can determine which activation function is better you will need sort out your data. Your data scaling is all over the place because of the lack of normalization. Once the site is working again I will help you with your other questions. Right now it is very difficult to use.
