Researchers introduce PACT, a post-training framework that enhances diffusion policies for robotic manipulation by ensuring physical safety constraints without sacrificing task performance. The method reduces safety violations by 31% while improving task success by 30.7% across simulated and real-world benchmarks.
Researchers demonstrate that Large Language Models exhibit inconsistent process alignment across organizational contexts, with the ability to replicate decision-making procedures varying significantly by both model and organizational type. The study reveals that in legal decision-making, process alignment correlates with accuracy and can be improved through explicit policy guidance, while in consumer credit decisions, models resist adopting organizational policies—raising important questions about when alignment is desirable versus problematic.
Researchers introduce PolicyBank, a memory mechanism that allows LLM agents to autonomously refine their understanding of organizational policies through iterative feedback and testing, rather than treating policies as immutable rules. The system addresses a critical AI alignment challenge where natural-language policy specifications contain ambiguities and gaps that cause agent behavior to diverge from intended requirements, achieving up to 82% closure of specification gaps compared to near-zero success with existing memory mechanisms.
Researchers present a new approach to aligning language models with human preferences that works without assuming a specific mathematical relationship between observed preferences and underlying rewards. The method frames policy alignment as a semiparametric optimization problem, enabling more robust policy learning even when the preference model structure is unknown or misspecified.
