Try other methods for vectorizing patterns

[bhu800]

Currently, the patterns have been vectorized into Bag of Words (BoW) Model, in a most simple way - on the basis of if the word is present in a pattern or not.

But since other factors like the frequency of that word in pattern might also play a role, we can try other approaches too like -

• CountVectorizer
• TF-IDF Vectorizer

Try models using different vectorizers and see which works best.
