Attention Hijacking: Backdooring Text Dataset Distillation via Semantic Anchors

ICML 2026poster

Dataset Distillation (DD) has emerged as a promising technique for compressing large-scale datasets into compact synthetic sets while preserving model performance. However, the security implications of this paradigm, particularly within the Transformer-based text classification domain, remain undere…

BDI-based Opponent Modeling and Strategy Generation for Multi-Issue Negotiation (Student Abstract)

AAAI 2026technical

Accurately modeling opponent behaviors and integrating strategy are key challenges for multi-issue automated negotiation. Existing approaches often isolate preference learning or trend prediction and lack a unified cognitive structure with coordinated reasoning. This paper proposes a BDI (Belief-Des

Reinforcement Learning in Presence of Discrete Markovian Context Evolution

ICLR 2022poster

We consider a context-dependent Reinforcement Learning (RL) setting, which is characterized by: a) an unknown finite number of not directly observable contexts; b) abrupt (discontinuous) context changes occurring during an episode; and c) Markovian context evolution. We argue that this challenging c…
