Multilabel Text Classification Using Deep Learning The model consists of a word embedding and GRU, max pooling operation, fully connected, and sigmoid operations. To measure the performance of multilabel classification, you can use the labeling F-score [2]. The labeling F-score evaluates multilabel classification by focusing on per-text classification with partial matches. Multi label text classification from thousands of labels I don't have machine learning experties, but I'm working on a project that has text classification requirements in it. The easiest approach I was able to understand was using fasttext.. It worked, but the accuracy is terrible. The problem is that we are trying to classify academic publications with multiple labels out of thousands of labels. Making predictions using all labels in multilabel text classification Multinomial Logistic Regression. To use a LogisticRegression classifier on all labels at once, set multi_class=multinomial. The softmax function is used to find the predicted probability of a sample belonging to a class. You'll need to reverse the one-hot encoding on the label to get back the categorical variable ( answer here).
