A Novel Active Noise Control Method Based on Variational Mode Decomposition and Gradient Boosting Decision Tree

Applied Sciences, 2023
Diversified noise sources pose great challenges in the engineering of an ANC (active noise control) system design. To solve this problem, this paper proposes an ANC method based on VMD (variational mode decomposition) and Ensemble Learning.

Efficient High-Dimensional Kernel k-Means++ with Random Projection

Applied Sciences, 2021
Using random projection, a method to speed up both kernel k-means and centroid initialization with k-means++ is proposed. We approximate the kernel matrix and distances in a lower-dimensional space Rd before the kernel k-means clustering motivated by ...
