I am currently studying LSTM and RNNs.



I came across several concepts like Multidimensional LSTM and Stacked LSTM.



I have used Stacked LSTM and it gives me a better performance than single LSTM. As per my understanding, if I increase the depth of LSTM, the number of hidden units also increases. It means overfitting, right? Then why am I getting better results?



[Note: I have used BatchNorm and Dropout after every stack of LSTM ]
