Approximately unbiased estimation of conditional variance in heteroscedastic kernel ridge regression
13 years 11 months ago
In this paper we extend a form of kernel ridge regression for data characterised by a heteroscedastic noise process (introduced in Foxall et al. [1]) in order to provide approxima...
