Conditional feature disentanglement learning for anomaly detection in machines operating under time-varying conditions

•Data-driven AD of machines under time-varying operating conditions is considered in this paper.•A feature disentanglement learning is proposed to solve entanglement between OCs and health states.•A Conditional VAE network combined with PCA is developed to realize the feature disentanglement and AD....
