I am trying to use kernel density estimate to non-parametrically smooth an option implied density. The shape of the distribution is highly dependent on the bandwidth. For my research purposes I would like to use cross validation (I've had spurious oscillations issues when using global band...

It should be noticed that in the ideal scenario where all of the samples are orthogonal concerning each other, this term becomes zero and the estimate is flawless. Inspired by this residual term, the inter-class crosstalk can be defined for binary classification problems, estimated as the ...
(the kernel) is averaged across the observed data points to create a smooth approximation. Also, KDE is a non-parametric density estimators, this means that the estimator has not a fixed functional form but only it depends upon all the data points we used to reach an estimate and the ...
