MemNMF: Memory-Augmented NMF on LPC Spectra for Anomalous Sound Detection

MemNMF is proposed, a constrained reconstruction method that operates on the Linear Predictive Coding spectrum, a compact estimate of the spectral envelope that improves a standard autoencoder baseline and yields further gains, with especially strong robustness under noisy, non-stationary settings.
