Timing decomposition | MATLAB implements Northern Goshawk optimization algorithm NGO optimization VMD signal component visualization

List of effects

basic introduction

Northern Goshawk optimization algorithm NGO optimizes VMD, optimizes the number of decomposition layers and the number of penalty factors, and uses NGO Northern Goshawk optimization algorithm to determine its optimal parameters, and the entropy value is the fitness function.
The programming language is matlab.
It can be used directly to replace the data.

programming

• How to obtain complete source code and data: Reply to MATLAB via private message to realize the visualization of VMD signal components optimized by the Northern Goshawk Optimization Algorithm NGO .
