It's slow by design, because it's optimized for readability. > tfidf = StemmedTfidfVectorizer(min_df=1, stop_words='english', analyzer='word', ngram_range=(1,1)) return lambda doc: english_stemmer.stemWords(analyzer(doc)) analyzer = super(TfidfVectorizer, self).build_analyzer() > class StemmedTfidfVectorizer(TfidfVectorizer): > english_stemmer = Stemmer.Stemmer('en') You can speed this up by using a smarter implementation of the Snowball stemmer, e.g., PyStemmer: > import Stemmer > tfidf = TfidfVectorizer(min_df=1, stop_words='english', analyzer='word', ngram_range=(1,1)) Unsurprisingly, it's NLTK that is slow: > tfidf = StemmedTfidfVectorizer(min_df=1, stop_words='english', analyzer='word', ngram_range=(1,1)) I tried converting the list X_train into an np.array but there was no difference in performance. # Line below takes 6-7 seconds on my machine The second series looks to deliver more of the same, so lets open the bags and take a look. Even if you had no plans to actually play the game with them, they were a worthwhile purchase.

#Review super vectorizer 2 code#
I am working on text data, and two lines of simple tfidf unigram vectorization is taking up 99.2% of the total time the code takes to execute. After thoroughly profiling my program, I have been able to pinpoint that it is being slowed down by the vectorizer.
