The method groups clients by data similarity and prioritizes those with higher loss, achieving up to 12% better accuracy while reducing communication overhead by 50%.
Researchers introduce VoxEmo, a comprehensive benchmark for evaluating Speech Large Language Models on emotion recognition tasks across 35 emotion corpora and 15 languages. The benchmark addresses evaluation challenges in open text generation and introduces novel protocols that better align with human subjective emotion perception.
Researchers developed CMA-ES-IG, a new algorithm that helps robots learn user preferences more effectively by incorporating user experience considerations. The algorithm suggests perceptually distinct and informative robot behaviors for users to rank, showing improved scalability, computational efficiency, and user satisfaction compared to existing methods.
Researchers propose RbtAct, a novel approach that uses peer review rebuttals as supervision to train AI models for generating more actionable scientific review feedback. The system leverages a new dataset RMR-75K and fine-tuned Llama-3.1-8B model to produce focused, implementable guidance rather than superficial comments.
Researchers have developed a pseudo-projector technique that can be integrated into existing transformer-based language models to improve their robustness and training dynamics without changing core architecture. The method, inspired by multigrid paradigms, acts as a hidden-representation corrector that reduces sensitivity to noise by suppressing directions from label-irrelevant input content.
