Researchers introduce SteerEval, a new benchmark for evaluating how controllable Large Language Models are across language features, sentiment, and personality domains. The study reveals that current steering methods often fail at finer-grained control levels, highlighting significant risks when deploying LLMs in socially sensitive applications.
Researchers introduce PsyAgent, a new AI framework that creates human-like agents by combining personality modeling based on Big Five traits with contextual social awareness. The system uses structured prompts and fine-tuning to produce AI agents that maintain stable personality traits while adapting appropriately to different social situations and roles.
Researchers introduce SensorPersona, an LLM-based system that continuously extracts user personas from mobile sensor data rather than chat histories, achieving 31.4% higher recall in persona extraction and 85.7% win rate in personalized agent responses. The system processes multimodal sensor streams to infer physical patterns, psychosocial traits, and life experiences across longitudinal data collected from 20 participants over three months.
Research reveals that large language models (LLMs) struggle to maintain consistent internal beliefs or goals across multi-turn conversations, failing to preserve implicit consistency when not explicitly provided context. This limitation poses significant challenges for developing persona-driven AI systems that require stable personality traits and behavioral patterns.
Researchers present AutoQD, a new AI method that automatically discovers diverse behavioral policies without requiring hand-crafted descriptors. The approach uses mathematical embeddings of policy occupancy measures to enable Quality-Diversity optimization algorithms to find varied high-performing solutions in reinforcement learning tasks.
Researchers evaluated how AI language models can be aligned to express distinct personalities when functioning as teammates, testing models from GPT-4o, Claude, Gemini, and Grok across personality traits. The study found that AI personalities are measurable but context-dependent, with personality signals more detectable in long-term memory representations than in conversation alone.
Researchers propose a new Persona Dynamic Decoding (PDD) framework that enables AI role-playing agents to dynamically adapt their personas based on context during inference time. The method uses psychological theories to estimate persona importance and adjust behavior without requiring expensive fine-tuning or static prompts.
Researchers have developed a new resource-rational framework for modeling visual attention as a sequential decision-making process using AI techniques like Partially Observable Markov Decision Processes. The framework successfully models human eye-movement behaviors in tasks like reading and multitasking, offering potential applications for Human-Computer Interaction design.
