English(EN) Characterizing the Performance Gap in Human Activity Recognition for Older Adults

AI活动识别模型在老年人方面表现出性能差距

作者 PulseAugur 编辑部 · [1 个来源] · 2026-10-05 04:00

一篇新发表在arXiv上的研究论文强调，尽管深度学习取得了进展，但在应用于老年人时，人类活动识别（HAR）模型存在显著的性能差距。研究人员发现，主要在年轻成年人数据上训练的模型无法有效地泛化到老年人群体，导致准确率持续存在差异。研究表明，利用更丰富的表征，例如在UK Biobank等多样化数据集上预先训练的自监督特征，可以显著提高老年人的HAR性能并缩小这一差距。 AI

影响强调了AI模型需要多样化的数据集和个性化适应，以确保在不同人群中实现公平的性能。
