The model is overfitting very fast. With just 10 epochs my model gets 97% accuracy from train data but only 62% on test data. I have tried changing the activation, reduce and increase the learning rate but the result is even worse and it never passes 62% accuracy. Is there any technique to increase the accuracy?
