Making reassignment adjustable: The Levenberg-Marquardt approach [PDF]
2012 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2012 This paper presents a new time-frequency reassignment process for the spectrogram, called the Levenberg-Marquardt reassignment. Compared to the classical one, this new reassignment process uses the second-order derivatives of the phase of the short-time Fourier transform, and provides the user with a setting parameter.

The Levenberg-Marquardt-Type Methods for a Kind of Vertical Complementarity Problem
Journal of Applied Mathematics, 2011 Two kinds of the Levenberg-Marquardt-type methods for the solution of vertical complementarity problem are introduced. The methods are based on a nonsmooth equation reformulation of the vertical complementarity problem for its solution.

Bootstrap Resampling in Gompertz Growth Model with Levenberg–Marquardt Iteration
JTAM (Jurnal Teori dan Aplikasi Matematika), 2022 Soybean plants have limited growth with a planting period of 12 weeks, which causes the observed sample to be very small. A small sample of soybean plant growth observations can be bias causes in the conclusion of prediction results on soybean plant ...

Levenberg-Marquardt Dynamics Associated to Variational Inequalities [PDF]
Set-Valued and Variational Analysis, 2017 In connection with the optimization problem $$\inf_{x\in argmin Ψ}\{Φ(x)+Θ(x)\},$$ where $Φ$ is a proper, convex and lower semicontinuous function and $Θ$ and $Ψ$ are convex and smooth functions defined on a real Hilbert space, we investigate the asymptotic behavior of the trajectories of the nonautonomous Levenberg-Marquardt dynamical system \begin ...
