MASCRDM: Multi-Agent System for Compliance Risk Detection and Mitigation in Training Process of Large Language Models

Sep 30, 2026

This study addresses the limitations of static compliance detection and the absence of end-to-end monitoring in large model training by proposing a dynamic compliance intervention mechanism grounded in internal model architectures, thereby transcending conventional input-output filtering paradigms. The proposed method constructs a multi-agent collaborative system that integrates compliance knowledge graphs, specialized large language models (LLMs), and instruction tuning techniques to decompose model nodes and enable real-time risk alerting and mitigation throughout the entire training pipeline. Experimental results demonstrate that this framework effectively reduces discrimination and bias risks while preserving semantic performance, achieving systematic improvements in model compliance.

VAD-Net: Multidimensional Facial Expression Recognition in Intelligent Education System

Dec 06, 2025

Existing facial expression recognition (FER) datasets predominantly provide only discrete emotion category labels, failing to capture fine-grained, continuous affective variations. Although some works incorporate Valence-Arousal (VA) annotations, the Dominance (D) dimension remains largely absent. This paper addresses this gap by introducing the first complete, human-verified three-dimensional Valence-Arousal-Dominance (VAD) continuous annotation for the FER2013 dataset. We further propose an orthogonal convolution-based ResNet regression architecture that enforces feature orthogonality to improve VAD value prediction accuracy. Experiments demonstrate that, despite its high annotation difficulty, the D dimension is effectively learnable; orthogonal convolutions significantly enhance predictive performance across all three dimensions—particularly for Dominance. The released VAD-annotated FER2013 dataset and open-source code establish a new benchmark for multidimensional affective computing, enabling more precise, granular emotion analysis in applications such as intelligent education.
