Diffraction separation by variational mode decomposition
Geophysical Prospecting, 2021ABSTRACTDiffracted wavefields with superior illumination encode key geologic information about small‐scale geologic discontinuities or inhomogeneities in the subsurface and thus possess great potential for high‐resolution imaging. However, the weak diffracted wavefield is easily masked by the dominant reflected data.

Generalized Variational Mode Decomposition: A Multiscale and Fixed-Frequency Decomposition Algorithm
IEEE Transactions on Instrumentation and Measurement, 2021To overcome the limitations of variational mode decomposition (VMD) algorithm that its frequency scales and spectrum positions cannot be flexibly adjusted to decompose signals as required, a generalized VMD (GVMD) was proposed. This article addresses the fundamental theory of GVMD. In order to highlight the local characteristics of the signal much more

Hierarchical decomposition based on a variation of empirical mode decomposition
Signal, Image and Video Processing, 2016Adaptive methods of signal analysis have proved a very useful tool for analysis of non-stationary signals. This is due to the ability of these methods to adapt to the local structures of the signals being analysed, as these methods are not constrained by a fixed basis.

Enhancement of variational mode decomposition with missing values
Signal Processing, 2018A new variational mode decomposition that efficiently handles missing data is proposed.A practical algorithm that reflects the adjustment of the missing sample effects under the framework of VMD algorithm is developed.Proposed method can be applicable to analyze various kind of signals through wavelet transform.

Bayesian Dynamic Mode Decomposition with Variational Matrix Factorization
Proceedings of the AAAI Conference on Artificial Intelligence, 2021Dynamic mode decomposition (DMD) and its extensions are data-driven methods that have substantially contributed to our understanding of dynamical systems. However, because DMD and most of its extensions are deterministic, it is difficult to treat probabilistic representations of parameters and predictions.

Radiometric identification using variational mode decomposition
Computers & Electrical Engineering, 2019Abstract Radiometric Identification (RAI) is the identification of wireless devices through their Radio Frequency (RF) emissions. In recent years, the research community has investigated it applying different methods and sets of statistical features extracted from the digitized RF emissions.

Two-Dimensional Variational Mode Decomposition
2015In this paper we propose a variational method to adaptively decompose an image into few different modes of separate spectral bands, which are unknown before. A popular method for recursive one dimensional signal decomposition is the Empirical Mode Decomposition algorithm, introduced by Huang in the nineties. This algorithm, as well as its 2D extension,
