How to get accuracy > 88

#1

I currently have accuracy of 88% using ngrams from 1 to 3. How to get 90% accuracy as others?

#2

Hey,
You can try to use more powerful networks like LSTMs for this task

#3

Others have probably got a higher accuracy using this same approach. What tuning can I do in this particular method?

Sorry for the late reply, they have got 89,90 with lstms only
