Certified Robustness to Text Adversarial Attacks by Randomized [MASK]

1 code implementation8 May 2021 Jiehang Zeng, Xiaoqing Zheng, Jianhan Xu, Linyang Li, Liping Yuan, Xuanjing Huang

Recently, few certified defense methods have been developed to provably guarantee the robustness of a text classifier to adversarial synonym substitutions.

SparseGAN: Sparse Generative Adversarial Network for Text Generation

no code implementations22 Mar 2021 Liping Yuan, Jiehang Zeng, Xiaoqing Zheng

It is still a challenging task to learn a neural text generation model under the framework of generative adversarial networks (GANs) since the entire training process is not differentiable.
