Adaptive Helpfulness-Harmlessness Alignment with Preference Vectors

Experiments show that the proposed Preference Vector framework improves helpfulness without excessive conservatism, allows smooth control over preference trade-offs, and supports scalable multi-preference alignment.

Steering Vector Fields for Context-Aware Inference-Time Control in Large Language Models

SVF is proposed, which learns a differentiable concept scoring function whose local gradient defines the steering direction at each activation, making interventions explicitly context-dependent and enables efficient long-form and multi-attribute control within a unified framework.

TRACES: Proactive Safety Auditing for Multi-Turn LLM Agents via Trajectory-State Modeling

TRACES is a representation-based proactive auditor that learns prefix-level trajectory risk states from the hidden representations of an observer LLM, and it is suggested that these risk states can help train a safer agent, highlighting the broader potential of proactive auditing for long-horizon agent safety.

TwinICL: Diagnosing Multimodal In-Context Learning through Paired Counterfactuals

In-context learning (ICL) enables models to infer tasks from demonstrations, but existing benchmarks generally lack matched text and image versions needed to compare ICL performance across modalities. We introduce TwinICL, a procedurally generated benchmark providing such pairs for controlled comparison. Across six ope...

ConstructCIE: A Dataset for Extracting Causal Information from Construction Accident Narratives

This work introduces ConstructCIE, a manually annotated dataset for Causal Information Extraction from OSHA construction accident reports, and evaluates supervised sequence taggers and instruction-tuned LLMs in an end-to-end hierarchical extraction setting.

PEPPER: Perception-Guided Perturbation for Robust Backdoor Defense in Text-to-Image Diffusion Models

PEPPER (PErcePtion-Guided PERturbation), a backdoor defense that rewrites the caption into a semantically distant yet visually similar caption while adding unobtrusive elements, achieves enhanced robustness without training or access to model weights.
