Kernel density estimation via diffusion

Abstract: We present a new adaptive kernel density estimator based on linear diffusion processes. The proposed estimator builds on existing ideas for adaptive smoothing by incorporating information from a pilot density estimate. In addition, we propose a new plug-in bandwidth selection method that is free from the arbitrary normal reference rules used by existing methods. We present simulation examples in which the proposed approach outperforms existing methods in terms of accuracy and reliability.Comment: Published in … Show more

“…This is accomplished by backtracking streamlines in time from x to the injection location. The resulting statistics of the TOF are needed to determine the distribution of Z( x,t) by means of kernel density estimation (KDE) (Botev et al, 2010). The TOF can also be estimated by solving an elliptic steady-state equation in Eulerian coordinates (Shahvali et al, 2012).…”

“…d, e Seismic refraction profiles made on and along the slope. Notice that the vertical and horizontal scales of P-1 and P-2 profiles are different in both plots identifies and defines the different planar discontinuities of the rock mass slope surface by applying an analysis based on a neighbouring points coplanarity test, finding principal orientations by the non-parametric technique Kernel Density Estimation (Botev et al 2010) and identifying clusters by the density-based scan algorithm with noise (Ester et al 1996). This information has allowed the identification of the most important discontinuity sets affecting the slope from the available 3DPC corresponding to 2011 (i.e.…”
