Disentangling Physical Parameters for Anomalous Sound Detection Under Domain Shifts

no code implementations12 Nov 2021 Kota Dohi, Takashi Endo, Yohei Kawaguchi

To solve this problem, the proposed method constrains some latent variables of a normalizing flows (NF) model to represent physical parameters, which enables disentanglement of the factors of domain shifts and learning of a latent space that is invariant with respect to these domain shifts.
