Papers with mask-then-infill procedure
Contextualized Perturbation for Textual Adversarial Attack (2021.naacl-main)
Copied to clipboard
| Challenge: | Existing techniques for generating adversarial examples are driven by local heuristic rules that are agnostic to the context, resulting in unnatural and ungrammatical outputs. |
| Approach: | They propose a ContextuaLized AdversaRial Example generation model that generates fluent and grammatical outputs through a mask-then-infill procedure. |
| Outcome: | The proposed model outperforms baseline models in terms of attack success rate, textual similarity, fluency and grammaticality. |
Controllable Fake Document Infilling for Cyber Deception (2022.findings-emnlp)
Copied to clipboard
| Challenge: | Existing approaches to deter malicious intrusion generate multiple fake versions of a document that are context-agnostic and produce sub-optimal outputs. |
| Approach: | They propose a context-aware model for creating fake documents that masks important concepts of varied lengths and then infills a realistic but fake alternative considering both the previous and future contexts. |
| Outcome: | The proposed model outperforms baseline models in generating highly believable fakes with moderate modification to protect critical information and deceive adversaries. |
