Am still not sure about a good solution for reducing vocabulary, but I think history needs to be additionally reduced too, perhaps using something like this:
historyCounts := historyCounts rejectWithOccurrences: [ :each :count |
count < aNumber ]
Because technically, if we are reducing the ngrams using the same threshold, then those words we are "throwing out" of ngramCounts
will have the same or even higher occurence in historyCounts
and therefore should be safe to delete. Tell me what you think, @olekscode.
In the method we are deleting ngrams and reducing history counts, i think vocabulary needs to be cleaned up too (when word history becomes zero, for instance).
The main idea of this method is to get rid of tokens and their sequences that we find irrelevant, in order to speed up reading from file or lookup within the model. And in this case always keeping all the vocabulary entries defeats the purpose.
