Deep neural networks (DNNs) are vulnerable to adversarial examples, perturbations to correctly classified examples which can cause the network to misclassify. In the image domain, these perturbations are often virtually indistinguishable to human perception, causing humans and state-of-the-art models to disagree. Deep neural networks (DNNs) are vulnerable to adversarial examples, perturbations to correctly classified examples which can cause the model to misclassify. However, in the natural language domain, small perturbations are clearly . For example, a generative model can successfully be trained to generate the next most likely video frames by learning the features of the previous frames. In this paper, we propose a geometry-inspired attack for generating natural language adversarial examples. In this paper, we focus on perturbations beyond word-level substitution, and present AdvExpander, a method that crafts new adversarial examples by expanding text. Here I wish to make a literature review on the paper Generating Natural Language Adversarial Examples by Alzantot et al., which makes a very interesting contribution toward adversarial attack methods in NLP and is published in EMNLP 2018. Fortunately, standard attacking methods generate adversarial texts in a pair-wise way, that is, an adversarial text can only be created from a real-world text by replacing a few words. turb examples such that humans correctly classify, but high-performing models misclassify.
