In science:

In this paper, we show one way to bring the Heston model into the realm of multi-scale stochastic volatility models without sacrificing analytic tractability.
A Fast Mean-Reverting Correction to Heston's Stochastic Volatility Model
Thus, the multi-scale model can be thought of as a Heston-like model with a fast-varying factor of volatility, f (Yt ), build on top of the CIR process Zt , which drives the volatility in the Heston Model.
A Fast Mean-Reverting Correction to Heston's Stochastic Volatility Model
P ǫ By setting V ǫ 1 = 0, P ǫ = PH , and the resulting implied volatility surface, obtained by inverting Black-Scholes formula, corresponds to the implied volatility surface produced by the Heston model.
A Fast Mean-Reverting Correction to Heston's Stochastic Volatility Model
In Figures 2 through 8, we plot the implied volatilities of call options on the market, as well as the calibrated implied volatility curves for the Heston and multi-scale models.
A Fast Mean-Reverting Correction to Heston's Stochastic Volatility Model
Such an extension constitutes the simplest stochastic volatility model within the BHM framework, which is shown to give sufficient flexibility to calibrate volatility surfaces.
