However, existing\napproaches struggle to capture the multi-dimensional, distributional nuances of\nhuman preferences. Methods such as RiC that directly inject raw reward value...

[ " Patients are increasingly turning to online health Q&A communities for social\nsupport to improve their well-being. However, when this support received does\nnot align with their specific needs, it may prove ineffective or even\ndetrimental. This necessitates a model capable of identifying the social\nsupport ne...

[ " Phishing attacks remain a critical cybersecurity threat. Attackers constantly\nrefine their methods, making phishing emails harder to detect. Traditional\ndetection methods, including rule-based systems and supervised machine learning\nmodels, either rely on predefined patterns like blacklists, which can be\nbyp...

[ " Reinforcement Learning with Human Feedback (RLHF) has achieved great success\nin aligning large language models (LLMs) with human preferences. Prevalent RLHF\napproaches are reward-based, following the Bradley-Terry (BT) model assumption,\nwhich may not fully capture the complexity of human preferences. In this ...

[ " Syntax connects words to each other in very specific ways. Two words are\nsyntactically connected if they depend\n directly on each other. Syntactic connections usually happen within a\nsentence. Gathering all those connection\n across several sentences gives birth to syntax networks. Earlier studies in\nthe f...

[ " Hallucinations pose a significant obstacle to the reliability and widespread\nadoption of language models, yet their accurate measurement remains a\npersistent challenge. While many task- and domain-specific metrics have been\nproposed to assess faithfulness and factuality concerns, the robustness and\ngeneraliz...

[ " LLMs have paved the way for truly simple document-level machine translation,\nbut challenges such as omission errors remain. In this paper, we study a simple\nmethod for handling document-level machine translation, by leveraging previous\ncontexts in a multi-turn conversational manner. Specifically, by decomposi...

[ " LLMs are often claimed to be capable of Natural Language Inference (NLI),\nwhich is widely regarded as a cornerstone of more complex forms of reasoning.\nHowever, recent works show that LLMs still suffer from hallucinations in NLI\ndue to attestation bias, where LLMs overly rely on propositional memory to\nbuild...
