Transforming text to numbers with BoW

Now that you've built a vocabulary from the customer reviews, you're ready to transform each review into a numerical format using the Bag-of-Words (BoW) model. This step creates a structured matrix where each row represents a review and each column corresponds to a word from the vocabulary.

The cleaned_reviews list and the fitted vectorizer are pre-loaded for you.
