无反向传播的学习规则在时间序列分类方面显示出潜力

作者 PulseAugur 编辑部 · [1 个来源] · 2026-11-02 05:00

研究人员探索了用于时间序列分类的无反向传播学习规则，将直接反馈对齐（DFA）、直接随机目标投影（DRTP）和NoProp等方法应用于一维卷积架构。在UCR档案中的112个数据集上，这些方法实现了0.76到0.79之间的平均F1分数，未能达到ROCKET和InceptionTime等成熟模型。研究发现，数据集中类内时间变异性是导致性能差距的主要因素，并且池化特征对DFA和DRTP的负面影响比标准反向传播更大。 AI

影响探索神经网络的替代训练方法，可能降低计算成本并解决反向传播的局限性。

Backpropagation-free Deep Learning for Time-Series Classification

arXiv:2610.41805v1 Announce Type: new Abstract: Deep neural networks for time series classification (TSC) are trained almost exclusively by error backpropagation, which imposes update locking and the weight-transport problem. Backpropagation-free learning rules such as Direct Fee…
