English(EN) An Interpretable Closed-Loop Intelligent Tutoring System for Multimodal Affective Feedback in Asynchronous Presentation Training

AI辅导系统通过多模态反馈提升公开演讲能力

作者 PulseAugur 编辑部 · [1 个来源] · 2026-05-25 04:00

研究人员开发了一个可解释的闭环智能辅导系统（ITS），旨在通过多模态反馈来提升公开演讲技能。该系统利用XGBoost模型分析视频片段中的面部、声音、文本和眼动特征，并根据七维评分标准提供反馈。该ITS在超过10,000个MOOC视频片段上进行了训练，其评分准确性可与专家评分相媲美，并在30天的练习期内显著提高了成人学习者的技能。 AI

影响展示了AI如何为技能发展提供结构化、可解释的反馈，从而可能改进教育工具。
