Multi-class text classification model with Keras. A step-by-step introduction. Originally published on Medium. NLP.

dataset = tf.keras.utils.get_file( fname="aclImdb.tar.gz", ... Feed the text classifier with training data. clf.fit(x_train, y_train, epochs=2) # Predict ...

Learn about Python text classification with Keras. Work your way from a bag-of-words model with logistic regression to more advanced methods leading to convolutional neural networks. See why word embeddings are useful and how you can use pretrained word embeddings. Use hyperparameter optimization to squeeze more performance out of your model.

Nov 06, 2019 · Text classification from scratch. Authors: Mark Omernick, Francois Chollet Date created: 2019/11/06 Last modified: 2020/05/17 Description: Text sentiment classification starting from raw text files.

May 10, 2020 · Introduction. This example demonstrates the implementation of the Switch Transformer model for text classification. The Switch Transformer replaces the feedforward network (FFN) layer in the standard Transformer with a Mixture of Expert (MoE) routing layer, where each expert operates independently on the tokens in the sequence.
