T3

This is the official code base for the EMNLP 2020 paper, "T3: Tree-Autoencoder Constrained Adversarial Text Generation for Targeted Attack".

This repo contains the code to attack both classification models (self-attentive models and BERT) and question answering models (BiDAF and BERT). We put our attack code in each folders.

You may use our code to attack other NLP tasks.

Note

Before using our T3(Sent), a tree-based autoencoder needs to be trained in a large corpus.

Train Tree-based Autoencoder

We trained our tree-based autoencoder on the Yelp review training dataset.

Related code can be found SAM-attack/my_generator/. Before training, each sentence in the training set should be parsed by Stanford CoreNLP Parser to get its dependency structures.

We also provide our pre-trained tree auto-encoder checkpoint here.
