Detecting Causality with Conjugation Quandles over Dihedral Groups
Zining Fan
We study whether quandle colorings can detect causality of events for links realized as skies in a -dimensional globally hyperbolic spacetime . Building off the Allen--Sw…
OPERA: Aligning Open-Ended Reasoning via Objective Perplexity-based Reinforcement Learning
Wenxuan Jiang, Zining Fan, Zijian Zhang +6
Reinforcement Learning (RL) has enabled LLMs to excel in objective reasoning tasks such as mathematics and code generation. However, applying RL to open-ended tasks, such as creati…
TR-ICRL: Test-Time Rethinking for In-Context Reinforcement Learning
Wenxuan Jiang, Yuxin Zuo, Zijian Zhang +8
In-Context Reinforcement Learning (ICRL) enables Large Language Models (LLMs) to learn online from external rewards directly within the context window. However, a central challenge…
Seamless Website Fingerprinting in Multiple Environments
Chuxu Song, Zining Fan, Hao Wang +1
Website fingerprinting (WF) attacks identify the websites visited over anonymized connections by analyzing patterns in network traffic flows, such as packet sizes, directions, or i…
