StegaVAR: Privacy-Preserving Video Action Recognition via Steganographic Domain Analysis

AAAI 2026technical

Despite the rapid progress of deep learning in video action recognition (VAR) in recent years, privacy leakage in videos remains a critical concern. Current state-of-the-art privacy-preserving methods often rely on anonymization. These methods suffer from (1) low concealment, where producing visuall

WET: Mitigating World-Conditioned Knowledge Conflicts via World Entropy Tethering

ICML 2026poster

Large language models (LLMs) face a "loyalty dilemma" when correctness is conditioned on an active world-of-discourse. We identify a systemic failure mode---world misattribution---where models implicitly ground generation in an incompatible regime and drift from the target world. We propose World En…

Quantifying and Analyzing Entity-Level Memorization in Large Language Models

AAAI 2024technical

Large language models (LLMs) have been proven capable of memorizing their training data, which can be extracted through specifically designed prompts. As the scale of datasets continues to grow, privacy risks arising from memorization have attracted increasing attention. Quantifying language model m…
