epoch loss and accuracy

[imranshaikmuma]

epoch training accuracy is not going above 60 percentage.
I tried with different optimizers like adam, sgd and learning rates like 0.1, 0.001, 1e-4, 0.5 etc and also with batch size like 16 and 8 and also number of rnn layers 3, 6, 12.

please let me know how to improve accuracy?
