Parzen Window Approximation on Riemannian Manifold
作者：
Highlights：
• High-density affinity drift is countered by local neighborhood based Parzen window.
• Variable Parzen window is able to adapt to the change in the sampling of data points.
• Affinity adjustment approximates unknown local neighborhood parameters.
• Affinity adjustment captures the difference in local distribution in a neighborhood.
