深度学习模型在机械故障诊断中的不确定性评估

一篇新发表在arXiv上的研究论文探讨了各种深度学习模型在诊断旋转机械故障方面的有效性,特别关注它们处理不确定性的能力。该研究比较了基于dropout的方法、贝叶斯神经网络和深度集成模型等,评估了它们在检测由未见故障(认知不确定性)和噪声(随机不确定性)引起的分布外数据方面的性能。研究结果表明,深度集成模型在检测认知不确定性方面通常优于其他模型,同时在抵抗随机不确定性方面也表现出更强的鲁棒性,因此因其准确性和效率而成为首选。 AI

影响 为在工业机械中选择具有不确定性感知能力的深度学习模型以实现可靠的故障诊断提供了指导。

    评估深度学习模型在旋转机械故障诊断中的认知不确定性和随机不确定性

    arXiv:2412.18980v2 Announce Type: replace Abstract: Uncertainty-aware deep learning (DL) models recently gained attention in fault diagnosis as a way to promote the reliable detection of faults when out-of-distribution (OOD) data arise from unseen faults (epistemic uncertainty) o…
