Fig. 9From: Transformer-based autoencoder with ID constraint for unsupervised anomalous sound detectionThe t-SNE visualization of latent feature on the test dataset for the machine type ToyCar using TransAE/LPE/CFP and IDC-TransAE. Different color represents different machine ID. The “\(\bullet\)” and “\(\times\)” denote normal and anomalous samples, respectivelyBack to article page
