Pre-processing
Simple changes in data pre-processing or the data cleaning stage can quite often give you dramatically better results. For instance, making sure that your entire corpus is in lowercase can help you reduce the number of unique words (your vocabulary size) by a significant fraction.
If your numeric representation of words is skewed by the word frequency, sometimes it helps to normalize and/or scale the same. The laziest hack is to simply divide by the frequency.
