LSTM TO STRING CATEGORICAL LABELS

1 view (last 30 days)
Hi Please help with with this code, there are two questions,
  1. Looks like my LSTM cannot achieve any better accuracy - what could be the cause?
  2. At the very end of the code, I wanted to to plot a confusion chart, - 1 - I used a for loop to capture the predicted labels from the trained network, is there a one line command for this type of data structure?
  3. Still on the confusion chart, what would be the best way to create the true labels set, I see the one I used in the function call for confusion chart is really incomplete, I am expecting the true labels set to be 40 x 5 matrix just like the test set.

Hi I managed to resolve the second part, I realized that I had not indexed my categorical lables properly on line 20 of the code.
I still want to know what the training can only achieve around 80 % accuracy. How can I improve this?

I realized that there was a problem in my data. I had some duplications, this has been sorted by cleaning my input file LSTMdataIn.xlsx
