- The Shape of Vulnerability: How Adversarial Perturbations Reshape the Topology of Language Model Latent Spaces (2026)
Adversarial prompts can push LLMs into degraded or harmful behaviour. Most interpretability tools look for linear features in isolated components, so they reveal little about how such inputs reshape a model's internal geometry. This ACL 2026 Student Research Workshop paper applies topological data analysis… - Using Topological Data Analysis to Characterize the Layers of Language Models Before and After Word Substitution Attacks (2026)
Synonym-swapping attacks such as TextFooler can flip a classifier's predictions. Existing analyses of these attacks examine only model outputs and reveal little about how the perturbation travels through the network. This paper uses topological data analysis (TDA) to trace how such attacks reshape attention maps at…
