Splet21. feb. 2024 · We have demonstrated this with synthetic documents where LSTM trounced the bags-of-words approach (Naive Bayes working with tf-idf vectors) for classification. But for a real text corpus of movie reviews for binary sentiment classification, we have shown that both LSTM and SVM (with tf-idf vectors) were comparable in quality even while the ...
