摘要

We propose a vibration event recognition method using fractional fourier transform (FrFT) and denoising diffusion probabilistic models (DDPM). The experimental results show that the model effectively identifies real vibration events by training on synthesized dataset, and it exhibits a high level of generalization ability.
