TL;DR: The article preprocesses the composite fault with ensemble empirical mode decomposition (EEMD) and then reconstructs the intrinsic mode function with the same time scale and proposes kurtosis spectral entropy as the objective function and uses the proposed method to search the complex fault pulse signals in strong noise environment.
Journal ArticleDOI
DR2: Diffusion-based Robust Degradation Remover for Blind Face Restoration
TL;DR: Wang et al. as mentioned in this paper proposed diffusion-based robust degradation removal (DR2) to transform the degraded image to a coarse but degradation-invariant prediction, then employ an enhancement module to restore the coarse prediction to a high-quality image.
Journal ArticleDOI
Application of Optimized Adaptive Chirp Mode Decomposition Method in Chirp Signal
TL;DR: A Rastrigin optimization test equation is proposed to test the optimization time of different species and determine the number of optimal species to improve the signal-to-noise ratio (SNR) and resolution of the signal.
