The tf-idf logistic regression that learns to assign weights to the words outperforms the rest tf-idf based models.ConclusionIn this article, I described the text classification models of the DeepPavlov framework..The relevant code can be found in the Colab notebook..These models were specifically developed to be effective for a small training dataset..However, if a large enough dataset is available, more sophisticated deep learning models can be applied.I would like to thank Mikhail Burtsev, Luiza Sayfullina, Olga Kairova, and the entire team of the iPavlov lab for the insightful comments..
