The SLV Calibrator is based on a method first proposed by Lipton [Risk, Feb 2002] and follows the implementation described in the Bloomberg paper "Stochastic Local Volatility" by Tataru & Fisher. The SLV Calibrator takes any calibrated LV surface that matches vanillas. Then, using a non-linear Fokker-Planck equation, it adds a SV component and for any given set of SV parameters computes a new "leveraged local volatility surface" that still matches the vanillas, while accommodating SV. The SLV Calibrator then applies to this PDE solution a Levenberg-Marquardt optimizer and finds the (time bucketed) SV parameters that yield a maximally flat leveraged local volatility surface.
At this point you have the pure LV model (the original LV surface) and the pure SV model (the SV parameters that yield a nearly flat leveraged LV surface). Both models fit the vanillas. The SLV Calibrator then solves for a mixing fraction the mixes the two models together either by a) calibrating to selected exotics, or b) using historical data.
