Researchers introduced CoRE, a benchmark testing whether large language models can reason about human emotions through cognitive dimensions rather than just labels. The study found that while LLMs capture systematic relations between cognitive appraisals and emotions, they show misalignment with human judgments and instability across different contexts.
Researchers conducted the first comprehensive analysis of emotion representations in small language models (100M-10B parameters), finding that these models do possess internal emotion vectors similar to larger frontier models. The study evaluated 9 models across 5 architectural families and discovered that emotion representations localize at middle transformer layers, with generation-based extraction methods proving superior to comprehension-based approaches.
Researchers developed a new method called activation engineering to make AI language models express more human-like emotions in conversations. The technique uses targeted interventions on LLaMA 3.1-8B to enhance emotional characteristics like positive sentiment and personal engagement without extensive fine-tuning.
Researchers developed a two-stage prompt selection strategy for zero-shot text-to-speech synthesis that improves emotional intensity and speaker consistency. The method evaluates prompts using prosodic features, audio quality, and text-emotion coherence in a static stage, then uses textual similarity for dynamic prompt selection during synthesis.
