Agreement-Constrained Probabilistic Minimum Bayes Risk Decoding

arXiv:2512.01316v1 Announce Type: cross Abstract: Minimum Bayes risk (MBR) decoding generates high-quality translations by maximizing the expected utility of output candidates, but it evaluates all pairwise scores over the candidate set; hence, it takes quadratic time with respect to the…

Mind the data gap: Missingness Still Shapes Large Language Model Prognoses

arXiv:2512.00479v1 Announce Type: new Abstract: Data collection often reflects human decisions. In healthcare, for instance, a referral for a diagnostic test is influenced by the patient’s health, their preferences, available resources, and the practitioner’s recommendations. Despite the extensive literature on…

Human Decision-making is Susceptible to AI-driven Manipulation

arXiv:2502.07663v3 Announce Type: replace Abstract: AI systems are increasingly intertwined with daily life, assisting users with various tasks and guiding decision-making. This integration introduces risks of AI-driven manipulation, where such systems may exploit users’ cognitive biases and emotional vulnerabilities to…

Clinical-R1: Empowering Large Language Models for Faithful and Comprehensive Reasoning with Clinical Objective Relative Policy Optimization

arXiv:2512.00601v1 Announce Type: new Abstract: Recent advances in large language models (LLMs) have shown strong reasoning capabilities through large-scale pretraining and post-training reinforcement learning, demonstrated by DeepSeek-R1. However, current post-training methods, such as Grouped Relative Policy Optimization (GRPO), mainly reward…

Template-assisted Contrastive Learning of Task-oriented Dialogue Sentence Embeddings

arXiv:2305.14299v2 Announce Type: replace-cross Abstract: Learning high quality sentence embeddings from dialogues has drawn increasing attentions as it is essential to solve a variety of dialogue-oriented tasks with low annotation cost. Annotating and gathering utterance relationships in conversations are difficult,…
