Dependency Reasoning for Aspect Sentiment Quadruple Prediction
Shima Esfandyar, Shima Esfandyari, Seywan Soleymanbaigi +3
Aspect Sentiment Quadruple Prediction (ASQP) is fundamentally a relational reasoning problem: identifying aspect-opinion-category-sentiment quadruples requires modeling structured…
Automated Detection and Structuring of Social Tipping Point Evidence in Climate related Documents: A Modular AI Framework
Kavindu Perera, Mohammad Abaeiani, Ekaterina Gilman +14
The climate literature has grown faster than review teams can read it. That gap matters most for a concept like the environmental social tipping point, the threshold at which a sma…
TUR-DPO: Topology- and Uncertainty-Aware Direct Preference Optimization
Abdulhady Abas Abdullah, Fatemeh Daneshfar, Seyedali Mirjalili +1
Aligning large language models (LLMs) with human preferences is commonly done via reinforcement learning from human feedback (RLHF) with Proximal Policy Optimization (PPO) or, more…
Beyond Wave Variables: A Data-Driven Ensemble Approach for Enhanced Teleoperation Transparency and Stability
Nour Mitiche, Farid Ferguene, Mourad Oussalah
Time delays in communication channels present significant challenges for bilateral teleoperation systems, affecting both transparency and stability. Although traditional wave varia…
