Abstract

Journal of Vibration and Control, Ahead of Print.
Deep learning has advanced machinery fault diagnosis, yet performance remains constrained by scarce and imbalanced labeled vibration data. We present ACS-DM, an adaptive conditional sampling diffusion framework that synthesizes frequency-faithful yet ...
