Joint Character-Level Convolutional and Generative Adversarial Networks for Text Classification

Abstract EN

With the continuous renewal of text classification rules, text classifiers need more powerful generalization ability to process the datasets with new text categories or small training samples.

In this paper, we propose a text classification framework under insufficient training sample conditions.

In the framework, we first quantify the texts by a character-level convolutional neural network and input the textual features into an adversarial network and a classifier, respectively.

Then, we use the real textual features to train a generator and a discriminator so as to make the distribution of generated data consistent with that of real data.

Finally, the classifier is cooperatively trained by real data and generated data.

Extensive experimental validation on four public datasets demonstrates that our method significantly performs better than the comparative methods.
