English(EN) MemNMF: Memory-Augmented NMF on LPC Spectra for Anomalous Sound Detection

新的MemNMF方法利用LPC频谱增强异常声音检测

作者 PulseAugur 编辑部 · [1 个来源] ·

研究人员开发了一种用于异常声音检测的新型方法MemNMF，该方法在LPC（线性预测编码）频谱上运行。该方法利用从非负矩阵分解（NMF）字典初始化的记忆模块，允许将输入重构为正常频谱模式的注意力加权组合。在MIMII和DCASE 2020 Task 2等基准数据集上的实验表明，MemNMF在标准自动编码器基线之上有所改进，尤其是在嘈杂和非平稳环境中。 AI
