> This improvement allows to prune the words with high document frequencies
> from the tf and tf-idf vectors produced by seq2sparse, based on the standard
> deviation of the words' document frequencies and specifying which rods to be
> pruned in a means of times this standard deviation. One good option is 3
> times the standard deviation
