Fisher-IRG: Fisher-Induced Local Invariant Representation Geometry across Language and Vision Models
Abdullah All Tanvir, Xin Zhong
Semantic-preserving transformations can induce substantial motion in learned representations, while small changes may strongly affect model predictions, raising a basic question: w…

Invariant Features in Language Models: Geometric Characterization and Model Attribution
Agnibh Dasgupta, Abdullah Tanvir, Xin Zhong
Language models exhibit strong robustness to paraphrasing, suggesting that semantic information may be encoded through stable internal representations, yet the structure and origin…

TIACam: Text-Anchored Invariant Feature Learning with Auto-Augmentation for Camera-Robust Zero-Watermarking
Abdullah All Tanvir, Agnibh Dasgupta, Xin Zhong
Camera recapture introduces complex optical degradations, such as perspective warping, illumination shifts, and Moiré interference, that remain challenging for deep watermarking sy…
